| 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 |
| Nov 6th Links: ASP.NET, ASP.NET AJAX, jQuery, ASP.NET MVC, Silverlight and WPF ... Last week was our big PDC conference, and I've been busy catching up back at work this week. I'm hoping to publish a bunch of new posts soon (including some on the PDC announcements we made). Until then, here is the latest in my link-listing series . Also check out my ASP.NET Tips, Tricks and Tutorials page and Silverlight Tutorials page for links to popular articles I've done myself in the past. ASP.NET 6 New ASP.NET Dynamic Data Videos : Joe Stagner has just published 6 new videos on the www.asp.net site that cover how to use the cool new ASP.NET Dynamic Data functionality introduced with .NET 3.5 SP1. 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. [AcceptVerbs] and [ActionName] attributes In our sample above we implemented ou | Go |
| Quick Update ... I've received a number of (very nice) emails recently asking if I was ok - since my blog has been silent the last few weeks (and much of the summer). Just to address people's concerns - I'm alive and well. :-) I've just been on vacation the last 6 weeks, and have unfortunately not had free time to post (I've been changing a lot of diapers). I am still on vacation another week before I officially return to work. I did get a chance to write up a quick post this weekend that covers some of the new ASP.NET MVC Preview 5 features, though, that will hopefully provide some interim reading until I can resume a more regular posting schedule over the next month when I get back into the office. Thanks, Scott P.S. Somewhat to my embarrassment I started a Part1/Part2 post on "Preview 4" right before I left for vacation, and didn't have time to finish part 2 before "Preview 5" came out. I am going to post this lost segment (which covered AJAX) later this month and write it against the latest preview build. P.P.S. People often ask me whether I write my own blog. Yep - I actually really do write every single post. Hopefully my absence the last 6 weeks provides some evidence to support this. :-) | Go |

| A Google Chart API Custom Server Control ... Last week's article, Creating Charts with the Google Chart API , looked at how
to use Google's free Chart API to generate line, pie, bar, and other types of charts from an ASP.NET page. The Google Chart API is callable via a
URL that contains the chart type, size, data, and other parameters in the querystring and returns the chart as an image. Displaying a chart
using this API is as simple as adding an Image Web control to a page and setting its ImageUrl property to the Google Chart API URL with
an appropriately formatted querystring.
Last week's article explored the essential querystring parameters and provided an example on how to programmatically
construct this querystring to plot data from a database query. In a nutshell, constructing this querystring involved about 50 lines of code
to get the data, express the data as percentages relative to one another, and build up the other parameters. Wouldn't it be much easier if we could
create a chart by dropping a Google Chart API Web control on the page, set a few properties, and then bind it to a data source control, like a
SqlDataSource or ObjectDataSource? That way we could create and display charts using the Google Chart API without having to write a lick of code.
Over the past week I built such a Web control. The Web control does not provide the full suite of Google Chart API features - it only allows for the
creation of line, bar, and pie charts, and it only allows a single data series - but it makes creating and displaying data-driven charts as easy as
drag-and-drop and point-and-click. This article shows how to use this free custom server control and highlights some of its more interesting aspects.
You can download the compiled server control, its complete source code, and a demo application at the end of this article. Read on to learn more!

| Customizing ASP.NET Dynamic Data ... From Wikipedia: “ASP.NET Dynamic Data is a web application scaffolding framework from Microsoft , shipped as an extension to ASP.NET , that can be used to build data driven web applications. ” So if you use VS2008 and .NET 3.5 SP1 you can take advantage of ASP.NET Dynamic Data to quickly create a full administration website (UI and CRUD) over a model (LINQ To SQL or better Entity Framework) on top of some db tables, and all this in about 3 minutes! Furthermore the system is very flexible and you can customize the look and feel of the generated web pages through a set of pages and user controls available on the DynamicData folder. But the default “3 minutes” experience create a web app that exposes CRUD operations on every tables/every columns… Default screen while editing the products table: What you may want to customize: Prevent some tables to be “scaffolded” Change table display name Format columns data Hide some columns (like Ids) This is the part where you’ll need to write a bit of code. In App_Code folder create new file that will hold several partial class to provides metadata information. You need to add 2 class for each entities in your model, one partial class with the name of the entity, and one sub-class to set metadata. The second one is “attached” to your entity class with the MetadataType attribute. C# snippet for Products entity: [MetadataType(typeof (Products_Metadata))]

| Edmonton Code Camp bound this Saturday ... What do 3 geeks do at 4AM in the parking lot of an IKEA in Calgary on a Saturday morning? Plot to overthrow Future Shop in the hopes of obtaining a rare shipment of WiiFits? Maybe. Test the cold-tolerance level of Dell laptops using Canadian Tire car batteries as their only source of power? Could be. Make cheap jokes about doing drag and drop presentations then have t-shirts made up to mock Microsoft employees?
Nah, they get together to drive to Edmonton and attend the Edmonton Code Camp silly.
That's what me and 2 of my very tired friends will be doing this Saturday (note, Tim Hortons will be our cuddly buddies come Saturday) as we head up to Edmonton, home of a hockey team that leaves their players quivering on the ice, questioning their sexuality.
I'll be presenting two fun-filled-uber-cool-extra-special-director-cut-edition-limited-time-only-before-they-go-back-into-the-vault sessions:
How to Win Friends and Influence People on Facebook, in .NET Yes, building Facebook apps isn't only restricted to PHP and procedural code. We'll go through building apps using the newly released 2.0 Facebook Toolkit for .NET and talk about restrictions that social networking sites put on how much information you can (and cannot) farm out of their API. And yeah, we'll build some cool Facebook games too (in .NET).
Building Really Cool Apps with WPF We'll do some cool stuff. It's a code camp. Bring yer laptops and fire up Visual Studio and we'll make XAML stand on it's head and do somersaults over any ORM anyday. jQuery? Bah. This is WPF baby and it your user experience doesn't get any richer than this.
My sessions are deemed a PowerPoint Free Zone to help make the planet a little nicer place to live in. Rock on big Al.
See you there! | Go |
| New Article: Creating a Custom View Engine in ASP.NET MVC ... I love how pluggable ASP.NET MVC is... this last article was fun, and I'm half tempted to start coding in HoTMeaT!
Here's a snippet of the good stuff:
<ul > <listView source ="{ViewData People}" > <itemTemplate > <li >{Binding LastName}, {Binding FirstName}</li > </itemTemplate > </listView ></ul >
And here's the HTML that it generates:

| A Conference for Technical Training? ... Posted at Ardent Dev by derek (Go directly to post ): If you want some hardcore technical training, do you go to a conference?
I don’t.
There’s so much great content available online. Much of it is free. And you can digest exactly what you need and skip things that are irrelevant to your immediate needs.
But conferences are incredibly valuable. I have had many "aha!" moments [...] Go to post | Go |

| SharePoint Administrator dissolves Webmaster role? ... I saw a general discussion on a SharePoint forum about SharePoint making the Webmaster role in organizations obsolete. Below was my response. I'm looking forward to hearing what the rest of the SharePoint community thinks. Personally, I think the title of 'webmaster' died quite some time ago. Due exclusively to SharePoint - no. To me the term Webmaster died because of all the new technologies that have evolved over the last 10 years. Was SharePoint a part of those of evolving technologies - yes. There are so many means and approaches to building an intranet/extranet/internet presence for an organization in this present day, that your typical 'webmaster' role with a small toolbox to get the job done is obsolete, along with the title. Just doing some searches on Monster.com reveals this I believe. SharePoint Administrator, you'll find about 300 jobs SharePoint Developer, you'll find about 650 jobs Webmaster, you'll only find about 100 jobs. As you can see SharePoint obviously has a higher demand than a Webmaster. But, if you try to be more general and look at all the available technologies, you'll see that SharePoint is just a small piece of the pie. Do a search for Web Developer, you'll find over 5,000+ jobs. Just Dan's 2 cents. | Go |

This is a great opportunity for first-time speakers and seasoned veterans alike. Contact me to receive the package. | Go |
| Object Oriented F# - Encapsulation with Object Expressions ... In the past, I've covered a bit about object oriented programming in F#. I'd like to come back to that series as there is much yet to cover on this topic. Last week, I spent some time with Erik Meijer at QCon and he and I both agreed that in some ways, F# is a better object oriented language than C# in some ways given some of the language flexibility.
Let's get caught up to where we are today:
Part 1 - Extension Everything
Part 2 - More Extension Everything
Part 3 - Creating Classes
Today's topic will be on object expressions and encapsulation in general.
Encapsulation
When we think of object oriented programming, encapsulation is a fundamental technique. This is to hide design decisions that are likely to change behind well-defined boundaries, and thus protecting parts of the program from that change. The benefits we get is that we can evolve our implementations over time without affecting other parts of our system. It's a pretty elementary topic and yet deeply important.
In F#, we have a couple of options we can talk about with regards to encapsulation which are object expressions and accessibility notations, the latter of which will be covered in a later post.
Object Expressions
One of the simplest ways of encapsulation in F# is to make them local to expressions or class definitions using the inner let bindings. These values are not directly accessible from outside the scope. Typically we use these to hold some sort of state which then is encapsulated inside implementation of our classes or expressions.
Let's look at a simple implementation of a counter that encapsulates state. We can encapsulate the state of the current count and then increment and have it keep count of our current state. Let's look at how we might do that in F#.
#light
open Xunit
let counter =
let count = ref 0
fun ( ) -> incr count; !count
[< Fact>]
let counter_should_increment( ) = let c1 = counter( )
let c2 = counter( )
Assert. Equal( c1, 1 )
Assert. Equal( c2, 2 )
You'll notice the use of the ref keyword which indicates that in order to properly be accessed and modified inside a closure, it cannot be mutable, but only a reference cell. Brian McNamara of the F# team recently covered this on a blog post about the F# ref type and On lambdas, capture and mutability . We also use the incr function which adds one to the reference cell. What's important to realize here is that the count reference cell is never exposed to the outside world, only its value through the function.
Object expressions are another interesting part of F#. This allows me to define local implementations of a given type and return it inline in a function, method or otherwise. Let's look at a few examples. The first one would be to create a comparer with two companies based upon size.
#light
type Company = { Name: string ; Size: int ; }
let companySizeComparer =
{ new System. Collections. Generic. IComparer<Company> with
override x. Compare( c1, c2) =
c1. Size. CompareTo( c2. Size)
}
[< Fact>]
let companySizeComparer_ShouldCompareSizes( ) =
let c1 = { Name = "Microsoft" ; Size = 70000 }
let c2 = { Name = "Google" ; Size = 20000 }
let c = companySizeComparer. Compare( c1, c2)
Assert. Equal( c, 1 )
Another example would be to create a Windows Form with an onload event prepopulated. Note that is is a pretty naive example of how you would use it, but it shows how you might override items in a given class.
#light
open System. Windows. Forms
let helloform =
{ new Form( ) with
member x. OnLoad( args) = base. OnLoad( args)
MessageBox. Show( "Hello World!" ) | > ignore
}
One last example I'll show is the simple map2 implementation from the F# libraries. This gives me the ability to combine two collections as one, which should be identical to the new impl | Go |
