| Introducing the ASP.NET MVC (Part 1) - The Model-View-Controller Patte ...

Both myself and Al are really looking forward to the day when this book ships, and we start receiving real feedback on all our hard work. However, both of us would like to start receiving feedback as soon as possible, so.
In an effort to write the book and keep blogging, I decided to open source the last chapter, Chapter 2, that I have to write. I am doing this so I can receive feedback on this chapter as early as possible. Because this chapter, in my opinion, is probably the most critical of the book, it defines the context around ASP.NET MVC and how it differs from ASP.NET Web Forms, as well as giving a historical perspective of the MVC pattern. | Go |

| New ASP.NET Charting Control: ... Microsoft recently released a cool new ASP.NET server control - <asp:chart /> - that can be used for free with ASP.NET 3.5 to enable rich browser-based charting scenarios: Download the free Microsoft Chart Controls Download the VS 2008 Tool Support for the Chart Controls Download the Microsoft Chart Controls Samples Download the Microsoft Chart Controls Documentation Visit the Microsoft Chart Control Forum Once installed the <asp:chart/> control shows up under the "Data" tab on the Toolbox, and can be easily declared on any ASP.NET page as a standard server control: <asp:chart /> supports a rich assortment of chart options - including pie, area, range, point, circular, accumulation, data distribution, ajax interactive, doughnut, and more. You can statically declare chart data within the control declaration, or alternatively use data-binding to populate it dynamically. At runtime the server control generates an image (for example a .PNG file) that is referenced from the client HTML of the page using a <img/> element output by the <asp:chart/> control. The server control supports the ability to cache the chart image, as well as save it on disk for persistent scenarios. It does not require any other server software to be installed, and will work with any standard ASP.NET page. To get a sense of how to use the <asp:chart /> control I recommend downloading the Microsoft Chart Controls Sample Project . This includes over 200 ASP.NET sample pages that you can run locally. Just open the web project in VS 2008 and hit run to see them in action - you can then open the .aspx source of each to see how they are implemented. The below example (under Chart Types->Line Charts->3D Line and Curve Charts) demonstrates how to perform Line, Spline and StepLine charting: The below example (under Chart Types->Pie and Doughnut Charts) demonstrates a variety of pie and 3D doughnut options: The below example (under Chart Types->Advanced Financial Charts) demonstrates some graph charts: In addition to the above samples, you can download the Microsoft Chart Control Documentation or ask questions on the Chart Controls Forum to learn more. This should provide a useful (and free) addition to your standard ASP.NET toolkit of functionality, and enable you to easily add richer visualization and data workflow scenarios to your ASP.NET applications. Hope this helps, Scott | Go |
| jQuery Intellisense in VS 2008 ... Last month I blogged about how Microsoft is extending support for jQuery . Over the last few weeks we've been working with the jQuery team to add great jQuery intellisense support within Visual Studio 2008 and Visual Web Developer 2008 Express (which is free). This is now available to download and use. Steps to Enable jQuery Intellisense in VS 2008 To enable intellisense completion for jQuery within VS you'll want to follow three steps: Step 1: Install VS 2008 SP1 VS 2008 SP1 adds richer JavaScript intellisense support to Visual Studio, and adds code completion support for a broad range of JavaScript libraries. You can download VS 2008 SP1 and Visual Web Developer 2008 Express SP1 here . Step 2: Install VS 2008 Patch KB958502 to Support "-vsdoc.js" Intellisense Files Two weeks ago we shipped a patch that you can apply to VS 2008 SP1 and VWD 2008 Express SP1 that causes Visual Studio to check for the presence of an optional "-vsdoc.js" file when a JavaScript library is referenced, and if present to use this to drive the JavaScript intellisense engine. These annotated "-vsdoc.js" files can include XML comments that provide help documentation for JavaScript methods, as well as additional code intellisense hints for dynamic JavaScript signatures that cannot automatically be inferred. You can learn more about this patch here . You can download it for free here . Step 3: Download the jQuery-vsdoc.js file We've worked with the jQuery team to put together a jQuery-vsdoc.js file that provides help comments and support for JavaScript intellisense on chained jQuery selector methods. You can download both jQuery and the jQuery-vsdoc file from the official download page on the jQuery.com site: Save the jquery-vsdoc.js file next to your jquery.js file in your project (and make sure its naming prefix matches the jquery file name): You can then reference the standard jquery file with an html <script/> element like so: Or alternatively reference it using the <asp:scriptmanager/> control, or by adding a /// <reference/> comment at the top of a standalone .js file. When you do this VS will now look for a -vsdoc.js file in the same directory as the script file you are referencing, and if found will use it for help and intellisense. The annotated For example, we could use jQuery to make a JSON based get request, and get intellisense for the method (hanging off of $.): As well as help/intellisense for the $.getJSON() method's parameters: The intellisense will continue to work if you nest a callback function within the method call. For example, we might want to iterate over each JSON object returned from the server: And for each of the items we could execute another nested callback function: We could use the each callback function to dynamically append a new image to a list (the image src attribute will point to the URL of the returned JSON media image): And on each dynamically created image we could wire-up a click event handler so that when it is pressed it will disappear via an animation: Notice how the jQuery intellisense works cleanly at each level of our code. JavaScript Intellisense Tips and Tricks Jeff King from the Web Tools team wrote up a great post earlier this week that answers a number of common questions about how JavaScript intellisense works with VS 2008. I highly recommend reading it. One trick he talks about which I'll show here is a technique you can use when you want to have JavaScript intellisense work within user-controls/partials (.ascx files). Often you don't want to include a JavaScript library <script src=""/> reference within these files, and instead have this live on the master page or content page the user control is used within. The problem of course when you do this is that by default VS has no way of knowing that this script is available within the user control - and so won't provide intellisense of it for you | Go |
| Update on Silverlight 2 - and a glimpse of Silverlight 3 ... We shipped Silverlight 2 last month. Over the last 4 weeks, the final release of Silverlight 2 has been downloaded and installed on more than 100 million consumer machines. It has also recently been published to corporate administrators via the Microsoft SMS and Microsoft Update programs to enable them to automatically deploy across enterprises. Over 1 in 4 computers on the Internet now have some version of Silverlight installed. Silverlight 2 was a major release, and delivered an impressive set of cross-browser, cross-platform functionality for Media and Rich Internet Application experiences. It has been great watching new sites launch using it. Media Experiences Silverlight 2 enables the highest quality video on the web, and delivers it with the lowest TCO of any media platform. One of the capabilities built-into Silverlight 2 is its support for "adaptive streaming" - which enables video to be delivered at multiple bitrates (for example: 400Kbits, 800Kbits, 1.5Mbits, 2Mbits) with Silverlight dynamically choosing the optimal bitrate to use depending on the network bandwidth and CPU capability of the client (it can also automatically switch bitrates seamlessly if conditions change later). Silverlight's adaptive streaming support is extensible. Move Networks (who helped pioneer the concept of adaptive streaming) have already integrated their adaptive streaming solution with Silverlight. Silverlight 2 and Move were used to stream the Democratic National Convention live on the web this summer. Last month we announced that Microsoft will be adding adaptive streaming support as a free feature of our IIS7 web-server. IIS Smooth Streaming will provide an integrated way to deliver HD quality adaptive video over the web. Visit Akamai's www.smoothhd.com site to see some awesome examples of Silverlight 2 and IIS Smooth Streaming in action (with adaptive streaming up to 2.5Mbits). The NBC Olympics site used Silverlight 2 to serve more than 3,500 hours of live and on-demand Olympic coverage to over 60 million unique visitors this summer. Visitors to the site watched an average of 27 minutes of video - which is stunningly high for online video. The site used the new Silverlight adaptive streaming capability to support 1.5Mbit bitrates - which helped deliver an awesome video experience: In addition to powering the Olympics experience in the US, Silverlight was also used in France (by FranceTV ), the Netherlands (by NOS ), Russia (by Sportbox.ru ) and Italy (by RAI ). In addition to video quality, a big reason behind these broadcasters decision to use Silverlight was the TCO and streaming cost difference Silverlight provided. In the August 2008 edition of Web Designer Magazine (a Dutch publication) a NOS representative reported that they were able to serve 100,000 concurrent users using Silverlight and 40 Windows Media Servers, whereas it would have required 270 servers if they had used Flash Media Servers. Over the last month we've seen several major new deployments of Silverlight for media scenarios. For example: CBS College Sports is now using Silverlight to stream NCAA events from its 170 partner colleges and university. Blockbuster is replacing Flash with Silverlight for its MovieLink application. And Netflix two weeks ago rolled out its new Instant Watch service using Silverlight. Rich Internet Applications (RIA) Experiences Silverlight 2 delivers a cross-browser, cross-platform subset of the .NET Framework, and enables developers to build Rich Internet Applications. Developers can use either VS 2008 or the free Visual Web Developer 2008 Express to open and edit Silverlight 2 projects, and get a powerful code-focused .NET development environment. Designers can use Expression Blend 2 SP1 to open and edit the same projects and use a creative tool to sculpt and create rich user experiences. I recently blogged about the nice dev | Go |
| Styling a Silverlight Twitter Application with Expression Blend 2 ... Silverlight 2 provides a rich platform for building cross-browser/cross-platform RIA applications. One of the things that makes Silverlight so powerful is the ease with which developers and designers can collaborate together on projects. Developers can use Visual Studio to open and edit Silverlight 2 projects and get a powerful code-focused .NET development environment, and designers can use Expression Blend 2 SP1 to open and edit the exact same project and use a creative tool to sculpt and create optimal user experience designs. The WPF UI framework shipped in Silverlight further enables a great designer/developer workflow by supporting concepts like layout management, controls, styles, templates, and resources - which help avoid scenarios where designers and developers end up tripping over each other when integrating functionality, behavior and expressive design. Silverlight 2 Twitter Sample Last month I posted an in-depth blog tutorial on how to build a Silverlight 2 Digg application which you can read here . This tutorial was aimed primarily at developers, and focused on introducing the fundamental programming concepts involved when building a Silverlight 2 application. Today Celso Gomes and Peter Blois posted a cool 10 minute video tutorial that shows off using Expression Blend to stylize a Silverlight 2 Twitter Messenger application. You can watch the video here . You can download the source code for the completed Silverlight Twitter application here . The video does a nice job demonstrating how designers can re-style a Silverlight application without having to mess with the code behind it. In the process it shows some of the power and capability that Expression Blend 2 provides to build really rich user experiences. Celso starts with a developer version of the application, and then customizes and sculpts the UI to have a fun twitter character theme: The Application Model The Silverlight Twitter client is hosted within an ASP.NET server application that exposes a web service that enables the Silverlight Twitter application to communicate to the Twitter service (since Twitter does not allow direct access from client applications). Communication between the Silverlight client and the ASP.NET web server is done using Windows Communication Foundation (WCF). The client application uses a Model-View-Presenter (MVP) pattern (also known as the Model-View-ViewModel pattern) which is commonly used in large WPF applications. Even though this is a fairly simple application they wanted to take advantage of the flexibility that MVP allows and allow room for future growth. Maintaining the separation between the visuals and the application logic also enables designers to make fairly complex visual changes without impacting the basic application flow. The video goes through some examples of the styling flexibility this architecture facilitates. The Styling Process In the video, Celso highlights how Resources can help designers quickly change colors. A common Brush Resource, for example, can be used to change the color of all the text elements in the application: Celso shows how easy is to create new User Controls from graphics using Expression Blend 2 SP1 (just select multiple elements in the designer, right-click, and choose the "Make Control" menu option): And also how to create new states inside this new User Control (using the Visual State Manager feature - which is also now supported with WPF), to animate the bird (fly, blink, etc...) Celso also shows how to create animations for each state, changing advanced properties like Key Spline curves, and Repeat Behavior: He also shows how to create custom buttons from drawings (which can come from XAML or any other design tool like Photoshop or Illustrator). All the states of a Button Control are available out of the box. Expression Blend also enables you to easily change complex controls like List Boxes. Designers have acce | Go |

Download Hotfix: False C# Compilation Errors for ASP.NET Code Behind Files with VS 2008 SP1 : The C# team added support for live semantic errors with background compilation in VS 2008 SP1. There were a few cases where this caused false errors to be shown with ASP.NET Web site projects. You can fix these either by disabling live semantic errors (tools->options allows you to disable this), or by downloading a recent hotfix patch which is now public. Omar Khan has a useful blog post with more details on it. Examining ASP.NET 2.0's Membership, Roles and Profile - Part 13 : Scott Mitchell has another post in his great series of ASP.NET security articles. This one covers how to create a login screen that allows admin users to log in as another user in the user database. For more on ASP.NET security, also check out Joe Stagner's recent ASP.NET Security Videos . ASP.NET Patterns Developers Should Know : Alex Homer from the Patterns and Practices (PAG) team at Microsoft has a nice article that introduces a number of common design patterns (MVC and MVP, Repository, Singleton, etc) and how you can apply them within ASP.NET applications.

| ASP.NET MVC Beta Released ... Today we released a beta of the new ASP.NET MVC framework. Click here to download it. You can also visit www.asp.net/mvc to explore tutorials , quickstarts , and videos to learn more. The ASP.NET MVC Beta works with both .NET 3.5 and .NET 3.5 SP1, and supports both VS 2008 and Visual Web Developer 2008 Express SP1 (which is free - and now supports class libraries and web application project types). Today's ASP.NET MVC Beta release comes with an explicit "go-live" license that allows you to deploy it in production environments. The previous preview releases also allowed go-live deployments, but did so by not denying permission to deploy as opposed to explicitly granting it (which was a common source of confusion). Today's release is clearer about this in the license. The beta release is getting close to V1 feature complete, although there are still a few more features that will be added before the final "V1" release (including several VS tooling enhancements). The team decided to call this release a "beta", though, because the quality and testing of it is higher than the previous previews (a lot of bug fixes and performance tuning work went into it), and they feel that the core features that are in it are now "baked enough" that there won't be major changes from this release to the final product. This post contains a quick summary of some of the new features and changes in this build compared to the previous "Preview 5" release: New "Add View" Menu in Visual Studio New \Scripts directory and jQuery Support Built-in Model Binder Support for Complex Types Refactored Model Binder Infrastructure Strongly Typed UpdateModel and TryUpdateModel WhiteList Filtering Improved Unit Testing of UpdateModel and TryUpdateModel Scenarios Strongly Typed [AcceptVerbs] attribute Better Validation Error Messages HTML Helper Cleanup and Refactoring Silverlight / ASP.NET MVC Project Integration ASP.NET MVC Futures Assembly \Bin and GAC Assembly Deployment I am also planning to publish a few end to end tutorials in the weeks ahead that explain ASP.NET MVC concepts in more depth for folks who have not looked at it before, and who want a "from the beginning" set of tutorials on how to get started. New "Add View" Menu in Visual Studio With previous ASP.NET MVC preview releases you had to manually add views through the Project->Add New Item dialog in VS, and creating and wiring up everything required several manual steps (making sure the directory/file structure is right, going into the code-behind file to specify the strongly typed ViewData model type, etc). Today's beta makes the steps much easier. You can now just move your source editor cursor to be within a Controller action method in the source editor, and then right-click and select a new "Add View" context menu item (alternatively you can type the Ctrl-M Ctrl-V keyboard shortcut to invoke this without having to take your hands off the keyboard): This will bring up a new "Add View" dialog that allows you to specify the name of the view you want to create, its master page, and optionally its strongly typed ViewData "Model" type: Visual Studio will automatically pre-populate the view name based on the action method your cursor is within (you can then override this if you want). For example, if our cursor had been within an "Edit" action method when we selected "add view" it would have pre-populated the view name textbox with "Edit" instead of "Browse". The strongly typed ViewData "model" for a view can be selected from an editable ComboBox that lists all classes in (or referenced) from the MVC project: You can either select a type from the list, or manually type one in the ComboBox. You can also optionally pick an initial type from the list and then tweak it. For example, we could select the "Product" class from the list and then use the ComboBox editing support to wrap it as an IEnumerable<Product> - meaning a sequence of pr | Go |
| Silverlight 2 Released ... Today we shipped the final release of Silverlight 2. You can download Silverlight 2, as well the Visual Studio 2008 and Expression Blend 2 tool support to target it, here . Cross Platform / Cross Browser .NET Development Silverlight 2 is a cross-platform browser plugin that enables rich media experiences and .NET RIAs (Rich Internet Applications) within the browser. Silverlight 2 is small in size (4.6MB) and takes only 4-10 seconds to install on a machine that doesn't already have it. It does not require the .NET Framework to be installed on a computer to run - the Silverlight setup download includes everything necessary to play video or run applications. Developers can write Silverlight applications using any .NET language (including VB, C#, JavaScript, IronPython and IronRuby). Silverlight provides a rich set of features for development including: WPF UI Framework : Silverlight 2 includes a rich UI framework that makes building rich Web applications much easier. In includes a powerful graphics and animation engine, as well as rich support for higher-level UI capabilities like controls, layout management, data-binding, styles, and template skinning. The WPF UI Framework in Silverlight is a compatible subset of the WPF UI Framework features in the full .NET Framework, and enables developers to re-use skills, controls, code and content to build both rich cross browser web applications, as well as rich desktop Windows applications. Rich Controls : Silverlight 2 includes a rich set of built-in controls that developers and designers can use to quickly build applications. The Silverlight 2 release includes core form controls (TextBox, CheckBox, RadioButton, ComboBox, etc), built-in layout management panels (StackPanel, Grid, Panel, etc), common functionality controls (Slider, ScrollViewer, Calendar, DatePicker, etc), and data manipulation controls (DataGrid, ListBox, etc). All Silverlight controls support a rich control templating model, which enables developers and designers to collaborate together to build highly polished solutions. Rich Networking Support : Silverlight 2 includes rich networking support. It includes out of the box support for calling REST, WS*/SOAP, POX, RSS, and standard HTTP services. It supports cross domain network access (enabling Silverlight clients to directly access resources and data from resources on the web). It also includes built-in sockets networking support. Rich Base Class Library : Silverlight 2 includes a rich .NET base class library of functionality (collections, IO, generics, threading, globalization, XML, local storage, etc). It includes rich APIs that enable HTML DOM/JavaScript integration with .NET code. It includes LINQ and LINQ to XML library support (enabling easy transformation and querying of data), as well as local data caching and storage support. The .NET APIs in Silverlight are a compatible subset of the full .NET Framework. Rich Media Support : Silverlight 2 includes built-in video codecs for playing high definition video, as well as for streaming it over the web (including both live and on-demand support). Silverlight includes support for adaptively switching video bitrates on the fly based on network conditions (enabling users to avoid seeing the dreaded "buffering..." message), placing and metering ads within video streams, as well as enabling content protection. The final Silverlight 2 release delivers a tremendous amount of power and flexibility that enables you to really push the boundaries of what can be done in a browser, and enable great end user experiences. Silverlight Customers Over the last few months a number of very high profile sites have successfully launched using the beta releases of Silverlight 2. In August, NBC hosted the Olympics live on nbcolympics.com and served up 1.3 billion page views, 70 million video streams, and 600 million minutes of video content - makin | Go |

| jQuery and Microsoft ... jQuery is a lightweight open source JavaScript library (only 15kb in size) that in a relatively short span of time has become one of the most popular libraries on the web. A big part of the appeal of jQuery is that it allows you to elegantly (and efficiently) find and manipulate HTML elements with minimum lines of code. jQuery supports this via a nice "selector" API that allows developers to query for HTML elements, and then apply "commands" to them. One of the characteristics of jQuery commands is that they can be "chained" together - so that the result of one command can feed into another. jQuery also includes a built-in set of animation APIs that can be used as commands. The combination allows you to do some really cool things with only a few keystrokes. For example, the below JavaScript uses jQuery to find all <div> elements within a page that have a CSS class of "product", and then animate them to slowly disappear: As another example, the JavaScript below uses jQuery to find a specific <table> on the page with an id of "datagrid1", then retrieves every other <tr> row within the datagrid, and sets those <tr> elements to have a CSS class of "even" - which could be used to alternate the background color of each row: [Note: both of these samples were adapted from code snippets in the excellent jQuery in Action book] Providing the ability to perform selection and animation operations like above is something that a lot of developers have asked us to add to ASP.NET AJAX, and this support was something we listed as a proposed feature in the ASP.NET AJAX Roadmap we published a few months ago. As the team started to investigate building it, though, they quickly realized that the jQuery support for these scenarios is already excellent, and that there is a huge ecosystem and community built up around it already. The jQuery library also works well on the same page with ASP.NET AJAX and the ASP.NET AJAX Control Toolkit. Rather than duplicate functionality, we thought, wouldn't it be great to just use jQuery as-is, and add it as a standard, supported, library in VS/ASP.NET, and then focus our energy building new features that took advantage of it? We sent mail the jQuery team to gauge their interest in this, and quickly heard back that they thought that it sounded like an interesting idea too. Supporting jQuery I'm excited today to announce that Microsoft will be shipping jQuery with Visual Studio going forward. We will distribute the jQuery JavaScript library as-is, and will not be forking or changing the source from the main jQuery branch. The files will continue to use and ship under the existing jQuery MIT license. We will also distribute intellisense-annotated versions that provide great Visual Studio intellisense and help-integration at design-time. For example: and with a chained command: The jQuery intellisense annotation support will be available as a free web-download in a few weeks (and will work great with VS 2008 SP1 and the free Visual Web Developer 2008 Express SP1). The new ASP.NET MVC download will also distribute it, and add the jQuery library by default to all new projects. We will also extend Microsoft product support to jQuery beginning later this year, which will enable developers and enterprises to call and open jQuery support cases 24x7 with Microsoft PSS. Going forward we'll use jQuery as one of the libraries used to implement higher-level controls in the ASP.NET AJAX Control Toolkit, as well as to implement new Ajax server-side helper methods for ASP.NET MVC. New features we add to ASP.NET AJAX (like the new client template support ) will be designed to integrate nicely with jQuery as well. We also plan to contribute tests, bug fixes, and patches back to the jQuery open source project. These will all go through the standard jQuery patch review process. Summary We are really excited to be able to partner w | Go |
| Silverlight 2 Release Candidate Now Available ... This evening we published the first public release candidate of Silverlight 2. There are still a small handful of bugs fixes that we plan to make before we finally ship. We are releasing today's build, though, so that developers can start to update their existing Silverlight Beta2 applications so that they'll work the day the final release ships, as well as to enable developers to report any last minute showstopper issues that we haven't found internally (please report any of these on the www.silverlight.net forums). Important: We are releasing only the Silverlight Developer Runtime edition (as well as the VS and Blend tools to support it) today, and are not releasing the regular end-user edition of Silverlight. This is because we want to give existing developers a short amount of time to update their applications to work with the final Silverlight 2 APIs before sites are allowed to go live with it. There are some breaking changes between Beta2 and this RC, and we want to make sure that existing sites can update to the final release quickly once the final release is out. As such, you can only use the RC for development right now - you can't go live with the new APIs until the final release is shipped (which will be soon though). You can download today's Silverlight Release Candidate and accompanying VS and Blend support for it here . Note that Expression Blend support for Silverlight 2 is now provided using Blend 2.0 SP1. You will need to install Blend 2.0 before applying the SP1 service pack that adds Silverlight 2 support. If you don't already have Blend 2.0 installed you can download a free trial of it here . Beta2->RC API Updates Today's release candidate includes a ton of bug fix and some significant performance optimization work. Today's release candidate also includes a number of final API tweaks designed to fix differences between Silverlight and the full .NET Framework. Most of these changes are relatively small (order of parameters, renames of methods/properties, movement of types across namespaces, etc) although there are a number of them. You can read this blog post and download this document to get a listing of the known API breaking changes made from the Beta2 release. We have updated the styles of the controls shipped with Silverlight, and have also modified some of the state groups and control template names they use. When upgrading from Beta2 you might find it useful to temporarily remove any custom style templates you've defined, and get your application functionality working using the RC first - and then after that works add back in the styles one style definition at a time to catch any rename/behavior change issues with them. If you find yourself stuck with an question/issue moving from Beta2 to the RC, please report it on the www.silverlight.net forums (Silverlight team members will be on there helping folks). If after a day or two you aren't getting an answer please send me email (scottgu@microsoft.com ) and I can help or connect you with someone who knows the answer. New Controls Today's release candidate includes a bunch of feature additions and tweaks across Silverlight 2, as well as in the VS and Blend tools targeting it. In general you'll find a number of nice improvements across the controls, networking, data caching, layout, rendering, media stack, and other components and sub-systems. Over the next few months we will be releasing a lot of new Silverlight 2 controls (more details on these soon). Today's release candidate includes three new core controls - ComboBox, ProgressBar, and PasswordBox - that we are adding directly to the core Silverlight runtime download (which is still only 4.6MB in size, and only takes a few seconds to install): At runtime these controls by default look like: The ComboBox in Silverlight 2 supports standard DropDownList semantics.

| ASP.NET MVC Preview 5 and Form Posting Scenarios ... This past Thursday the ASP.NET MVC feature team published a new "Preview 5" release of the ASP.NET MVC framework. You can download the new release here . This "Preview 5" release works with both .NET 3.5 and the recently released .NET 3.5 SP1. It can also now be used with both Visual Studio 2008 as well as (the free) Visual Web Developer 2008 Express SP1 edition (which now supports both class library and web application projects). Preview 5 includes a bunch of new features and refinements (these build on the additions in "Preview 4" ). You can read detailed "Preview 5" release notes that cover changes/additions here . In this blog post I'm going to cover one of the biggest areas of focus with this release: form posting scenarios. You can download a completed version of the application I'll build below here . Basic Form Post with a Web MVC Pattern Let's look at a simple form post scenario - adding a new product to a products database: The page above is returned when a user navigates to the "/Products/Create" URL in our application. The HTML form markup for this page looks like below: The markup above is standard HTML. We have two <input type="text"/> textboxes within a <form> element. We then have an HTML submit button at the bottom of the form. When pressed it will cause the form it is nested within to post the form inputs to the server. The form will post the contents to the URL indicated by its "action" attribute - in this case "/Products/Save". Using the previous "Preview 4" release of ASP.NET we might have implemented the above scenario using a ProductsController class like below that implements two action methods - "Create" and "Save": The "Create" action method above is responsible for returning an html view that displays our initial empty form. The "Save" action method then handles the scenario when the form is posted back to the server. The ASP.NET MVC framework automatically maps the "ProductName" and "UnitPrice" form post values to the method parameters on the Save method with the same names. The Save action then uses LINQ to SQL to create a new Product object, assigns its ProductName and UnitPrice values with the values posted by the end-user, and then attempts to save the new product in the database. If the product is successfully saved, the user is redirected to a "/ProductsAdded" URL that will display a success message. If there is an error we redisplay our "Create" html view again so that the user can fix the issue and retry. We could then implement a "Create" HTML view template like below that would work with the above ProductsController to generate the appropriate HTML. Note below that we are using the Html.TextBox helper methods to generate the <input type="text"/> elements for us (and automatically populate their value from the appropriate property in our Product model object that we passed to the view): Form Post Improvements with Preview 5 The above code works with the previous "Preview 4" release, and continues to work fine with "Preview 5". The "Preview 5" release, though, adds several additional features that will allow us to make this scenario even better. These new features include: The ability to publish a single action URL and dispatch it differently depending on the HTTP Verb Model Binders that allow rich parameter objects to be constructed from form input values and passed to action methods Helper methods that enable incoming form input values to be mapped to existing model object instances within action methods Improved support for handling input and validation errors (for example: automatically highlighting bad fields and preserving end-user entered form values when the form is redisplayed to the user) I'll use the remainder of this blog post to drill into each of these scenarios.

| SSRS Export Feature Causes an ""Object Moved"" Error ... I ran into the following issue with SSRS 2005 where some users would run a report and then try to export it into a different format (Excel, PDF, etc) using the SSRS web site tool bar resulting in an "Object Moved" error. Some would see the error in a pop-up message box or as an ASP.Net Server Error page after clicking the Open or Save As button on the download dialog (depending on what IE browser version they were using).
After some investigating a lot of things (including spending a lot of time looking at server logs) it was discovered that this isn't a server problem at all. Instead it is an error that occurs for some users based on their IE settings. Since the SSRS site was being run under an SSL certificate when the following IE setting is enabled it can cause the "object moved" error when a user tries to download the report: "Do not save encrypted pages to disk". Go to the advanced tab in IE settings and uncheck this option if you are experiencing the error when exporting reports in an SSL protected SSRS web site.

| SharePoint + jQuery = Stay Here Feature ... Fun with jQuery and SharePoint
In my previous post I showd how to create a slideshow in SharePoint with the help of jQuery and the Cycle plugin. Yesterday someone asked me for a feature that takes care of opening all external urls in a new window. That makes sense doesn't it. You do not want visitors to leave your SharePoint site to soon. You want them to Stay Here . And with our jQuery feature in place it's a piece of cake so I decided to create the motion10 Stay Here feature.
The code
All this feature needs is a little javascript. This script must select al hyperlinks on the page that do not have the target attribute set and a different host than the current host. When we have the selected links we need to add the target attribute and that's all. So here's the script.
$(function() {
$('a').filter(function() {
return !this.target && this.hostname && this.hostname !== location.hostname;
}).each(function(){$(this).attr("target", "_blank")});
});
How to create a feature
Actually we would like to have this script in all pages of our sitecollection. Hmmmm.... that sounds familiar doesn't it? Again we can use the Delegate Control to add this script to the head of every page. So the script goes to the layouts directory and we create a User Control that just contains a script reference.
.cf { font-family: Consolas; font-size: 11pt; color: white; background: black; font-weight: bold; height:300px; overflow:auto; }.cl { margin: 0px; }.cb1 { color: #cc7832; }.cb2 { color: #a5c25c; }
<% @ Control="" Language="C#" ClassName="jQueryStayHereControl" % >
<script type="text/javascript" src="/_layouts/jQuery/Plugins/jquery.stayhere.js" ></script >
And just like we did with our Cycle plugin we add this control to our elements collection.
<?xml version="1.0" encoding="utf-8" ?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/" >
<Control
Id="AdditionalPageHead"
ControlSrc="~/_controltemplates/jQuery/Plugins/jQueryStayHereControl.ascx"
Sequence="1" />
</Elements >
We must not forget our jQuery dependency though. So in our feature.xml we add an Activation Dependency and that's all.
<?xml version="1.0" encoding="utf-8" ?>
<Feature Id="853d13a2-3bbf-411e-b8a5-ef0a30d4636f"
Title="motion10 jQuery Stay Here Plugin"
Description="If you enable this feature all external links on your site will be opened in a new window."
Version="12.0.0.0"
Hidden="FALSE"
Scope="Site"
DefaultResourceFile="core"
Creator="Wesley Bakker"
ImageUrl="motion10/FeaturesIcon.png"
ImageUrlAltText="http://www.motion10.com"
xmlns="http://schemas.microsoft.com/sharepoint/" >
<ActivationDependencies >
<ActivationDependency FeatureId="f805f632-a321-435c-9d13-025454e3fd5a" />
</ActivationDependencies >
<ElementManifests >
<ElementManifest Location="elements.xml" />
</ElementManifests >
</Feature >
By activating the feature the user control is added to the head of our page which loads the script which in turn makes all of our links to external websites open in a new window.
Please do feel free to download the motion10 SharePoint Solution Pack. It contains all of the source and an installation folder. Oh... and you might find some extra features in there. I'll try to add a new feature every two weeks and update the package. So if you do have some good ideas for features just leave me a comment or drop me an email and we'll se what I can do. I hope my next feature will enable Google Analytics on your site. Busy with that one because I need to add an application page to enable you to configure your Google user account id.

| Optimizing your route collection for URL generation in ASP.NET MVC (and more!) ... If you're used ASP.NET MVC or ASP.NET Dynamic Data , you've using ASP.NET's new Routing feature. ASP.NET Routing is the feature that lets you easily create so-called "pretty" URLs. Pretty URLs are the ones that look the way you want them to look (e.g. ~/products/beverages), not the way your web application platform forces them to look (e.g. ~/products.aspx?categoryname=beverages). Many people, including myself, have blogged about the various features of Routing, but this post is about optimizing your routes to get the most out of them. Here are some tricks to make URL generation more performant in your application: 1. Use named routes Named routes are an optional feature of routing. The names are only used for URL generation; they are never used for matching incoming URLs. When you specify a name when generating a URL we will only try to match the one route with that name. This means that even if the named route you specified is the 100th route in the route table we'll jump straight to it and try to match. Otherwise we'd try every single route until we get to the 100th route. Here's an example of using named routes in an MVC application: // Global.asax.cs routes.MapRoute(
"products-route" ,
"products/{category}" ,
new {
controller = "products" ,
action = "category" ,
});
// Views/Home/Index.aspx
<% = Html.RouteLink("Show Beverages" , "products-route" , new { category = "beverages" }) %>
Note that if we hadn't specified the name route, we would probably get a different route to match. Also, because we used the named route, we didn't have to specify any extra route values such as the controller or action name.
2. Put your most common routes at the beginning of the route table
This will improve performance of both URL generation as well as processing incoming URLs. The Routing system works on a very simple rule: the first match wins. If the first match happens to be the 100th route in your route table, then that means it had to try 99 other routes and none of them matched. By putting your most common routes towards the top of the route collection, they will match sooner.
However, be careful: Changing the order of your routes can affect how they match. Only change the order of the routes if you're sure that it won't cause a conflict.
3. Don't use URL generation
Some people like URL generation and some people don't. It's a bit tricky to master URL generation. It's nice to use URL generation if your URLs are very dynamic and you don't want to update your whole site when you make changes to your URL structure. But it can be a bit of a hassle when you have very few URLs to begin with and perhaps you don't care about exactly what they look like.
My favorite
My favorite option is #1, using named routes, primarily since it's super easy to use. It also makes URL generation more deterministic from the app developer's perspective (that's you!). By giving things names and then specifying exactly what you won't, it eliminates the guessing game of routes. | Go |
| Handling Dynamic Storyboards and Animations in Silverlight 2 ... Animations are a key part of Silverlight 2 that allow your applications to stand out from all of the boring and dull applications floating around on the Web. In previous articles I’ve written about storyboards and animations but as a quick review, Silverlight relies upon a Storyboard element to define several different types of animations such as DoubleAnimation (which animates object properties of type double) and ColorAnimation (which animates color properties). In this article I’ll show you how Silverlight can be used to create animations programmatically and how you can interact with animations defined declaratively in a XAML file using C#.
For this example I’ll create a simple “lightbox” style container that can display pictures from Flickr. As the picture is being shown the box will grow from a height/width of 0 to a larger size that’s determined by the size of the browser. Three different animations will be performed by the image display container:
Animate the Width from 0 to the width of the browser / 1.5
Animate the Height from 0 to the height of the browser / 1.5
Animate the Opacity from 0 to 1
If you know the To and From values of the animations upfront then it’s easiest to define them in the XAML file. In cases where there’s an unknown animation property value, you can create the storyboard and animation objects programmatically or update properties of an existing Storyboard defined in XAML. In this case a Border control will be animated: < Border x : Name ="LightBoxControl" BorderBrush ="Black" BorderThickness ="3"
CornerRadius ="10"
Height ="20" Width ="20" Opacity ="0" Margin ="5"
MouseLeftButtonDown ="Image_MouseLeftButtonDown">
< Border.Background >
< LinearGradientBrush EndPoint ="0.893,0.116" StartPoint ="0.403,0.694">
< GradientStop Color ="#FFB9B9B9" Offset ="1"/>
< GradientStop Color ="#FF4F4F4F" Offset ="0"/>
< GradientStop Color ="#FF666666" Offset ="0.496"/>
</ LinearGradientBrush >
</ Border.Background >
< StackPanel x : Name ="spImage">
< Border HorizontalAlignment ="Right" VerticalAlignment ="Top" BorderBrush ="Black"
BorderThickness ="1" CornerRadius ="8" Background ="LightGray" Width ="60" Height ="25">
< TextBlock HorizontalAlignment ="Center" VerticalAlignment ="Center" FontSize ="12"
Text ="Close" />
</ Border >
< Rectangle x : Name ="LightBoxImage" HorizontalAlignment ="Center"
Fill ="Black" RadiusX ="10" RadiusY ="10"
Stroke ="LightGray" StrokeThickness ="2" Margin ="5">
</ Rectangle >
</ StackPanel >
</ Border >
Here’s an example of programmatically creating a Storyboard and defining the 3 animations mentioned earlier to change the Width, Height and Opacity properties of the Border control: double ? width = (double ?)System.Windows.Browser.HtmlPage .Document.Body.GetProperty("offsetWidth" ) / 1.5;
double ? height = (double ?)System.Windows.Browser.HtmlPage .Document.Body.GetProperty("offsetHeight" ) / 1.5;
//Programmatic way to create a storyboard and animations
Storyboard sb = new Storyboard ();
//Create animation for Border control's Width
DoubleAnimation wa = new DoubleAnimation ();
wa.Duration = new Duration (TimeSpan .FromSeconds(0.5))
wa.From = 0;
wa.To = width;
Storyboard .SetTarget(wa, LightBoxControl);
Storyboard .SetTargetProperty(wa, new PropertyPath (Border .WidthProperty));
sb.Children.Add(wa);
//Create animation for Border control's Height
DoubleAnimation ha = new DoubleAnimation ();
ha.Duration = new Duration (TimeSpan .FromSeconds(0.5));
ha.From = 0;
ha.To = height;
Storyboard .SetTarget(ha, LightBoxControl);
Storyboard .SetTargetProperty(ha, new PropertyPath (Border .HeightProperty));
sb.Children.Add(ha);
//Create animation for Border control's Opacity
DoubleAnimation oa = new DoubleAnimation ();
oa.Duration = new Duration (TimeSpan .FromSeconds(0.5));
oa.From = 0;
oa.To = 1;

| Using XAML serialization in WCF 4.0 ... Declarative Services is one of the exciting new features of Windows Communication Foundation (WCF) 4.0. By declarative, we are referring to services that are completely modeled by using the Extensible Application Markup Language (XAML). As you might think, this capability will open to door for a whole new set of scenarios in Service Oriented systems which are really hard to implement with the current technologies. The specific capabilities of declarative services will be the subject of a future post...(read more ) | Go |
| ADO.NET Linq to Entities versus Linq to SQL ... I recently did a project using LINQ to SQL. I decided to convert it to the ADO.NET Linq to Entities model instead. It was fairly easy to convert with a few gotchas. I will list the changes here:
Linq to SQL
ADO.NET Linq to Entities
Creating a Model:Add New Item: Linq to SQL Classes
Creating a Model:Add New Item: ADO.NET Entity Data Model
query = _
(From m In dc.Menu _
Where m.menuId = menuId _
Select m).SingleOrDefault()
SingleOrDefault is not supported in the current Entities releases (talk has it that it will be added in future releases). So use FirstOrDefault() in your Linq to SQL if you want your code to be forward compatible with Entities.
query = _
(From m In dc.Menu _
Where m.menuId = menuId _
Select m).FirstOrDefault()
Linq to SQL Deletion and Submitting Changes:
Dim dc As New MyEntities()
Dim menuDetail = _
(From md In dc.Menu _
Where md.menuId = menuId _
Select md).FirstOrDefault
If Not menuDetail Is Nothing Then
dc.Menus.DeleteOnSubmit(menuDetail)
dc.SubmitChanges()
End If
Linq to Entities Deletion and Submitting/Saving Changes:
Dim dc As New MyEntities
Dim menuDetail = _
(From md In dc.Menu _
Where md.menuId = menuId _
Select md).FirstOrDefault
If Not menuDetail Is Nothing Then
dc.DeleteObject(menuDetail)
dc.SaveChanges()
End If
dc.Menu.InsertOnSubmit(myRecord)
dc.AddToMenu(myRecord)
Also, the Linq to SQL messes with the "s" on the end of table names and Linq to Entities does not.
If I've made some mistakes, feel free to educate me. :)
May your dreams be in ASP.NET!

| You've got to see this! ... Believe it or not, sometimes Infragistics releases even catch me by surprise. Well, that happened today. I knew that we were targeting the middle of December for our Silverlight LOB CTP , but I've been so busy lately I didn't even notice it's already the middle of December! My wife told me that Christmas is only a week away and I didn't believe her. I did the math.. she was right. Guess I should start shopping. Back to the CTP.. Stop what you're doing and go check out http://labs.infragistics.com/silverlight/lobsamples/ . I'll wait for you, I promise. That magical experience you just had.. was Silveright. I'm a huge fan of the Grid control, especially the Hierarchical Financial Data example. I've seen so many customers build that style UI in the past, I already know it's going to be a hit. There are plenty more features to come in the grid, but this is an absolutely amazing start. And did you notice the performance? In the Hierarchical Data example, there have to be close to 1000 records in total (it's a 3 level hierarchy..) and it loaded and performed like it was nothing! Add Tree, Editors, Spell Checker and OutlookBar to the mix, and this is starting to feel more like a release than a CTP! You can download the CTP today, and I encourage you to share your questions and thoughts in the Silverlight Forum . | Go |
| Dica de preenchimento de Listbox e DropDown com fonte de dados ... Algumas pessoas tem me questionado como adicionar items a um controle APÓS ter feito o datasource e o databind. Normalmente usamos o seguinte código:
string[] dados = { "teste1", "teste2", "teste3", "teste4" };lstProdutos.DataSource = dados;lstProdutos.DataBind();
Mas se vc tentar adicionar algum item entre o DataSource e o DataBind,nada funcionará pq o DataBind irá renderizar o controle somente com a fonte.
string[] dados = { "teste1", "teste2", "teste3", "teste4" };lstProdutos.DataSource = dados;lstProdutos.Items.Add(new ListItem("ultimo item", "ultimo"));lstProdutos.Items.Insert(0, "novo item");lstProdutos.DataBind();
Mas seus problemas acabaram :) pq no ASP.NET 3.5 existe a propriedade AppendDataBoundItems que permite adicionar items mesmo antes do DataBind. Veja o exemplo:
string[] dados = { "teste1", "teste2", "teste3", "teste4" };lstProdutos.AppendDataBoundItems = true; // NOVA PROPRIEDADElstProdutos.DataSource = dados;lstProdutos.Items.Add(new ListItem("ultimo item", "ultimo"));lstProdutos.Items.Insert(0, "novo item");lstProdutos.DataBind();
Faça um bom uso deste código e aplique-o nos seus projetos. | Go |
