| ASP.NET MVC Storefront Part 23: WebForms and Dynamic Data ... A few months back I got to talking to J Sawyer who is a Developer Evangelist in the Texas area about the work I've been doing with the MVC Storefront. Before I worked at Microsoft, J was my "main man" with the Commerce Starter Kit - the very first Open Source project I ever worked on.
During the course of the conversation J asked me if I had any plans to do any "WebForm-y" stuff; and I said "no" since this was supposed to be an ASP.NET MVC project. But then I started thinking...
ASP.NET 3.0 doesn't have any Starter Kits out there (that I know of) and it's time we had one :). If I've done my job right - J should be able to take the back-end goodness (Services, Data Access, Unit Tests, etc) and put them behind an ASP.NET WebForms site. And he did!
And thus CSK 3.0 is born. | Go |

| 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. In addition to statically defining items like above, you | Go |
| 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 |
| ASP.NET MVC Preview 4 Release (Part 1) ... The ASP.NET MVC team is in the final stages of finishing up a new "Preview 4" release that they hope to ship later this week. The Preview 3 release focused on finishing up a lot of the underlying core APIs and extensibility points in ASP.NET MVC. Starting with Preview 4 this week you'll start to see more and more higher level features begin to appear that build on top of the core foundation and add nice productivity. There are a bunch of new features and capabilities in this new build - so much in fact that I decided I needed two posts to cover them all. This first post will cover the new Caching, Error Handling and Security features in Preview 4, as well as some testing improvements it brings. My next post will cover the new AJAX features being added with this release as well. Understanding Filter Interceptors Action Filter Attributes are a useful extensibility capability in ASP.NET MVC that was first added with the "Preview 2" release. These enable you to inject code interceptors into the request of a MVC controller that can execute before and after a Controller or its Action methods execute. This enables some nice encapsulation scenarios where you can easily package-up and re-use functionality in a clean declarative way. Below is an example of a super simple "ScottGuLog" filter that I could use to log details about exceptions raised during the execution of a request. Implementing a custom filter class is easy - just subclass the "ActionFilterAttribute" type and override the appropriate methods to run code before or after an Action method on the Controller is invoked, and/or before or after an ActionResult is processed into a response. Using a filter within a ASP.NET MVC Controller is easy - just declare it as an attribute on an Action method, or alternatively on the Controller class itself (in which case it will apply to all Action methods within the Controller): Above you can see an example of two filters being applied. I've indicated that I want my "ScottGuLog" to be applied to the "About" action method, and that I want the "HandleError" filter to be applied to all Action methods on the HomeController. Previous preview releases of ASP.NET MVC enabled this filter extensibility, but didn't ship with pre-built filters. ASP.NET Preview 4 now includes several useful filters for handling output caching, error handling and security scenarios. OutputCache Filter The [OutputCache] filter provides an easy way to integrate ASP.NET MVC with the output caching features of ASP.NET (with ASP.NET MVC Preview 3 you had to write code to achieve this). To try this out, modify the "Message" value set within the "Index" action method of the HomeController (created by the VS ASP.NET MVC project template) to display the current time: When you run your application you'll see that a timestamp updates each time you refresh the page: We can enable output caching for this URL by adding the [OutputCache] attribute to the our Action method. We'll configure it to cache the response for a 10 second duration using the declaration below: Now when you hit refresh on the page you'll see that the timestamp only updates every 10 seconds. This is because the action method is only being called once every 10 seconds - all requests between those time intervals are served out of the ASP.NET output cache (meaning no code needs to run - which makes it super fast). In addition to supporting time duration, the OutputCache attribute also supports the standard ASP.NET output cache vary options (vary by params, headers, content encoding, and custom logic). For example, the sample below would save different cached versions of the page depending on the value of an optional "PageIndex" QueryString parameter, and automatically render the correct version depending on the incoming URL's querystring value: You can also integrate with the ASP.NET Database Cache Invalidation feature - which allows you t | Go |
| Silverlight 2 Beta2 Released ... Silverlight 2 Beta2 was released today. You can download both Silverlight 2 Beta2 and the Visual Studio and Expression Blend tools support to target it here . Beta2 adds a lot of new features (more details below), but is still a 4.6 MB download that takes less than 10 seconds to install on a machine. It does not require the .NET Framework or any other software to be installed for it to work, and all features work cross-browser on both Mac and Windows machines. These features will also be supported on Linux via the Moonlight 2 release. Silverlight 2 Beta2 supports a go-live license that allows you to start using and deploying Silverlight 2 for commercial applications. There will be some API changes between Beta2 and the final release, so you should expect that applications you write with Beta2 will need to make some updates when the final release comes out. But we think that these changes will be straight-forward and relatively easy, and that you can begin planning and starting commercial projects now. You can build Silverlight Beta2 applications using the VS 2008 Tools for Silverlight and Expression Blend 2.5 June Preview downloads. You can download both of them here . The VS 2008 Tools for Silverlight download works with both VS 2008 and the recent VS 2008 SP1 beta release. UI and Control Improvements Silverlight 2 Beta2 includes a bunch of work in the UI and Control space: More Built-in Controls In Beta 1 only a few controls were included with the core Silverlight setup. Most common controls (including Button, ListBox, Slider, etc) were shipped within separate assemblies that you had to bundle with your applications (which increased the app download size). Beta 2 now installs 30+ of the most common controls as part of the core Silverlight 2 download. This means that you can now build Silverlight 2 applications that use core controls that are as small as 3kb in size - making Silverlight application downloads small and startup time fast. In addition to the core controls included with the base Silverlight 2 setup, we are also this week shipping additional higher-level controls that are implemented in separate assemblies that you can then reference and include with your applications. This includes controls like DataGrid (more details on its new Beta2 features below), Calendar (now with multi-day selection and blackout date support in Beta2), and a TabPanel control (new in Beta2). We ultimately expect to ship over a 100 controls for Silverlight. Control Template Editing Support One of the most powerful features of the WPF and Silverlight programming model is the ability to completely customize the look and feel of controls. This allows developers and designers to sculpt the UI of controls in both subtle and dramatic ways, and enables a tremendous amount of flexibility. I covered these concepts a little in my previous Silverlight Control Templating blog post here . This week's Expression Blend 2.5 June Preview now adds designer support for editing control templates - which makes it easy for you to quickly change the look of any control without having to drop-down to XAML source to-do it. To see control template editing in action, just drag/drop two Slider controls onto the Expression Blend design surface: We might decide that the slider head in the default Slider control template is too large and wide for our application. To use control template editing to change it, we can right-click on one of the sliders in the designer and select the "Edit Control Parts" context menu item. We can choose to create a new empty control template for our slider (and start from scratch), or alternatively edit a copy of the built-in control template (and start from that and tweak it): After we choose to edit a copy of the existing control template, Blend will prompt us to create and name a re-usable style resource that we'll define our control template wit | Go |
| ASP.NET MVC Support with Visual Web Developer 2008 Express ... Last week I blogged about the ASP.NET MVC Preview 3 release . One important thing I forgot to mention about this release is that you can now use it with both Visual Studio 2008 as well as the free Visual Web Developer 2008 Express edition. The SP1 release of Visual Web Developer 2008 Express adds support for both class library projects as well as web application projects (previously only web site projects could be used with it). This new support is useful in itself, as well as in enabling both ASP.NET MVC and Silverlight project support with VWD Express. If you install the Visual Web Developer Express SP1 Beta you can start using ASP.NET MVC Preview 3 with it immediately. Important: ASP.NET MVC Preview 3 does not require SP1 to be installed if you are using Visual Studio 2008. ASP.NET MVC Preview 3 will work with both VS 2008 and VS 2008 SP1 just fine. You can learn more about the new VWD Express support for ASP.NET MVC from the VS Web Tools team blog here . This post also includes a free web download that provides ASP.NET MVC Test project support for NUnit-based unit tests. You can use these NUnit project templates with both Visual Studio 2008 as well as with Visual Web Developer Express 2008. Hope this helps, Scott | Go |
| ASP.NET MVC Preview 3 Release ... This morning we released the Preview 3 build of the ASP.NET MVC framework. I blogged details last month about an interim source release we did that included many of the changes with this Preview 3 release. Today's build includes some additional features not in last month's drop, some nice enhancements/refinements, as well as Visual Studio tool integration and documentation. You can download an integrated ASP.NET MVC Preview 3 setup package here . You can also optionally download the ASP.NET MVC Preview 3 framework source code and framework unit tests here . Controller Action Method Changes ASP.NET MVC Preview 3 includes the MVC Controller changes we first discussed and previewed with the April MVC source release , along with some additional tweaks and adjustments. You can continue to write controller action methods that return void and encapsulate all of their logic within the action method. For example: which would render the below HTML when run: Preview 3 also now supports using an approach where you return an "ActionResult" object that indicates the result of the action method, and enables deferred execution of it. This allows much easier unit testing of actions (without requiring the need to mock anything). It also enables much cleaner composition and overall execution control flow. For example, we could use LINQ to SQL within our Browse action method to retrieve a sequence of Product objects from our database and indicate that we want to render a View of them. The code below will cause three pieces of "ViewData" to be passed to the view - "Title" and "CategoryName" string values, and a strongly typed sequence of products (passed as the ViewData.Model object): One advantage of using the above ActionResult approach is that it makes unit testing Controller actions really easy (no mocking required). Below is a unit test that verifies the behavior of our Browse action method above: We can then author a "Browse" ViewPage within the \Views\Products sub-directory to render a response using the ViewData populated by our Browse action: When we hit the /Products/Browse/Beverages URL we'll then get an HTML response like below (with the three usages of ViewData circled in red): Note that in addition to support a "ViewResult" response (for indicating that a View should be rendered), ASP.NET MVC Preview 3 also adds support for returning "JsonResult" (for AJAX JSON serialization scenarios), "ContentResult" (for streaming content without a View), as well as HttpRedirect and RedirectToAction/Route results. The overall ActionResult approach is extensible (allowing you to create your own result types), and overtime you'll see us add several more built-in result types. Improved HTML Helper Methods The HTML helper methods have been updated with ASP.NET MVC Preview 3. In addition to a bunch of bug fixes, they also include a number of nice usability improvements. Automatic Value Lookup With previous preview releases you needed to always explicitly pass in the value to render when calling the Html helpers. For example: to include a value within a <input type="text" value="some value"/> element you would write: The above code continues to work - although now you can also just write: The HTML helpers will now by default check both the ViewData dictionary and any Model object passed to the view for a ProductName key or property value to use. SelectList and MultiSelectList ViewModels New SelectList and MultiSelectList View-Model classes are now included that provide a cleaner way to populate HTML dropdowns and multi-select listboxes (and manage things like current selection, etc). One approach that can make form scenarios cleaner is to instantiate and setup these View-Model objects in a controller action, and then pass them in the ViewData dictionary to the View to format/render. For example, below I'm creating a SelectList view-model class over the | Go |

| Introducing grid client-side editing support with Q3 2008 ... With our upcoming version of RadControls for ASP.NET AJAX (early November) you will be able to bind our grid even if the grid is in edit mode. RadGrid will locate automatically all built-in column editors (GridNumericColumn, GridDropDownColumn, GridDateTimeColumn, etc.) and you can get old/new values directly from the grid client-side API.
You can use client-side editing completely codeless with templates as well. The requirement here is to set ID for the control to be equal to desired data field.
Example :
<telerik:GridTemplateColumn HeaderText="CompanyName">
<EditItemTemplate>
<telerik:RadTextBox ID="CompanyName" runat="server" />
</EditItemTemplate>
</telerik:GridTemplateColumn>
We have introduced also three new client-side methods for GridTableView to get new values, old values and keys for particular GridDataItem.
Example :
var newValues = $find("RadGrid2").get_masterTableView().extractValuesFromItem(0) ; // get first item new values
var newValues = $find("RadGrid2").get_masterTableView().extractOldValuesFromItem(0) ; // get first item old values
var newValues = $find("RadGrid2").get_masterTableView().extractKeysFromItem(0) ; // get first item keys
I've made small example using two grids (master/detail) both bound completely client-side to illustrate this new functionality:
Enjoy!

| Using Regular Expression TextBox ... I've already blogged about the new RadInputManager control in the Beta of Q3 2008 for RadControls ASP.NET AJAX .
One of the other very useful features that you can now take advantage of in the RadInputManager is its RegExpTextBox setting. Regular expressions are a good way to validate text fields such as names, addresses, phone numbers, and other user information. You can use it to constrain input, apply formatting rules, and check lengths.
If you capture input by using TextBox controls, you can use the RegExpTextBoxSetting settings to validate that input - for example to restrict the range of valid characters, to strip unwanted characters, and to perform length and format checks. You can constrain the input format by defining patterns that the input must match.
To validate a TextBox control's input using a RegExpTextBoxSetting
1. Add a RadInputManager control to your page.
If you click the "Configure Input Manager " link it will bring up the following dialog:
2 . Select what type of setting you will be adding
3. Select "Telerik.Web.UI.RegExpTextBoxSetting " and indicate which TextBox controls will be extended.
4. Select the ValidationExpression property and choose an appropriate regular expression. Set the ErrorMessage property to define the message to display if the validation fails.
5. Press "OK" and start the application.
DemoRadInputManager4ASPNETAJAX
Summary
Input validation can become a security issue if an attacker discovers that you have made unfounded assumptions. The attacker can then supply carefully crafted input that compromises your application by attempting SQL injection, cross-site scripting, and other injection attacks. To avoid such vulnerability, you should validate text fields (such as names, addresses, tax identification numbers, and so on) and use a RadInputManager to do that. The RadInputManager architecture makes it really easy to encapsulate UI functionality and behavior.
For more information, see the regular expression tutorial at http://www.regular-expressions.info/tutorial.html .

| Zip Compressing ASP.NET Session without changing your code using a Session provider. ... Scott Hanselman had a post last week to zip your Session state. a great idea I thought to be able to save memory on the computer. Yet I didn’t want to change all my source code to use another class to do so, a nightmare to track all the Sessions in every application, or worse when you don’t have access to that source code. So last weekend I work on a Session State Provider that allows me to intercept every call to the Session State and compressed when set or unzip when retrieve. The Session State provider will call my method by adding this to the web.config on your website: < sessionState cookieless = "true " regenerateExpiredSessionId = "true " mode = "Custom " customProvider = "ZipSessionProvider ">
< providers >
< add name = "ZipSessionProvider " type = "ZipSession.ZipSessionProvider "/>
</ providers >
</ sessionState >
This tells the web application to send all Session request to my class ZipSessionProvider that wraps Scott Hanselman’s class. There are 2 methods that are important on the provider, to set the session and to retrieve. So users don’t have to change the code to use the Sessions on their web applications:
Session["Something" ] = "Hello World" ;
Insert a Session object.
public override void SetAndReleaseItemExclusive
(HttpContext context, String id, SessionStateStoreData item,
object lockId, bool newItem)
{
for (int i = 0; i < item.Items.Count; i++)
{
string sKey = item.Items.Keys[i];
Zip .Session[id + sKey] = item.Items[i];
}
}
The system calls the SetAndReleaseItemExclusive to set Session variables. As when you override the Session state, you’ll find you won’t get a Session initialize for you. That’s ok or better, as we’ll use the Cache object to store our session state, more control over that. The method above will store the sessionID as well with the Key for easy retrieve later on.
Retrieve a session object.
public override SessionStateStoreData GetItemExclusive
(HttpContext context, String id, out bool locked,
out TimeSpan lockAge, out object lockId,
out SessionStateActions actions)
{
actions = SessionStateActions .None;
lockId = null ;
lockAge = TimeSpan .MaxValue;
locked = true ;
SessionStateStoreData temp = new SessionStateStoreData (
new SessionStateItemCollection (),
SessionStateUtility .GetSessionStaticObjects(context),
20
);
for (int i = 0; i < Zip .SessionItems.Count; i++)
{
if (Zip .SessionItems[i].ToString().Contains(id))
{
string sKey = Zip .SessionItems[i].ToString().Replace(id, "" );
temp.Items[sKey] = Zip .Session[Zip .SessionItems[i].ToString()];
}
}
return temp;
}
Even if we call the SessionStateStoreData we need to provide all the objects and the correct name as well as filtered by Session id.
Modification on Scott’s code.
I had to make 2 modification on Scott’s code, not to fix errors, just to adjusted to my needs.
public class ZipCacheInternal
{
public object this [string index]
{
get
{
return GZipHelpers .DeCompress(HttpContext .Current.Cache[index] as byte []);
}
set
{
HttpContext .Current.Cache[index] = GZipHelpers .Compress((string )value );
SessionItems.Add(index);
}
}
}
Instead of be a string indexer I changed it to be able to store any kind of object as well as I keep track of all session on an Array.
Testing the code.
Now we can run the code to test the application, a simple web form with 2 buttons, one to set and the other one to retrieve the session previously set.
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false )
{
Session["Something" ] = "Hello World" ;
Response.Write("Test" );
Label1.Text = "" ;
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Label1.Text = Session["Something" ].ToString();
}
protected void Button2_Click(object sender, EventArgs e)
{

| RegisterHiddenField within dynamically created controls ... I've been building a composite control that has a client-side object associated with it. Any changes on the client are persisted back to the server through a hidden field and the server-side object is updated with these changes. I register the hidden field with the page in the OnPreRender event of the control. This works well with statically created controls.
I ran into trouble when I was creating these controls dynamically. My controls were being created and added to the Page on every postback in the Page's OnInit event. However, when it came time for the control to save its client state in the hidden field, the hidden field couldn't be found!
What's wrong here? Here is a snippet from my control's code: protected override void OnPreRender(EventArgs e)
{
ScriptManager sm = ScriptManager.GetCurrent(Page);
if (sm == null)
{
throw new InvalidOperationException("A ScriptManager is required on this page");
}
base.OnPreRender(e);
ClientScript.RegisterHiddenField(this.ClientStateID, "");
}
Nothing! (at least that's what I thought). See if you can spot the difference in this next snippet: protected override void OnPreRender(EventArgs e)
{
ScriptManager sm = ScriptManager.GetCurrent(Page);
if (sm == null)
{
throw new InvalidOperationException("A ScriptManager is required on this page");
}
base.OnPreRender(e);
ScriptManager.RegisterHiddenField(this, this.ClientStateID, "");
}
After cracking open the source code to the AjaxControlToolkit, I saw that the experts were calling the ScriptManager's static method in order to register the hidden field with the page. I'm not sure why you can't call the Page's ClientScript's method instead, but just in case anyone else runs up against this, I thought I'd throw this out there to help. | Go |

C# 1.0 Managed code C# 2.0 Generics C# 3.0 Language integrated query C# 4.0 Dynamic programming C# vNext Compiler as a service Trends Declarative Dynamic Concurrent Dynamic Concurrent New paradigm is multi paradigm. C# is very object oriented, but since C# 3.0 it is also a functional programming. These trends are influencing the future of C# coming in C# 4.0 Dynamic language runtime build up out of expression trees, dynamic dispatch, call site caching. The DLR will have binders for different technologies. Dynamic typed Objects Statically typed to be dynamic Dynamic conversion Dynamic method invocation example: dynamic calc = GetCalculator(); int sum = calc.Add(10, 20); *Anders Hejlsberg shows a pretty impressive demo in which he copies a JavaScript fragment into a .cs file and runs it by changing explicit typed variables with the new dynamic keyword. How does this work? IDynamicTypedObject is the new interface to implement. Implementing the object GetMember(..) and void SetMember(..) of these interface definition is enough to create dynamic objects. *You can think of this as native support for DuckTyping. Perhaps this will even bring Arjen over to the bright side. Optional and named parameters *A restriction is that a named parameter must come last. Improved COM interoperability Automatic object -> dynamic mapping Optional and named parameters Indexed property Optional "ref" modifier Interop type embedding ("No PIA") no primary interop assembly Co- and contra-variance objects[0] = "Hello"; // OK objects[1] = new Button(); // Exception! .NET arrays are co-variant, but not safely co-variant Until now generics have been invariant C# 4.0 now supports safe co-and contra invariance. IEnumerable<out T> out = Covariant output positions only. IComparer<in T> in = Contra-variant input positions only. Variance in C# 4.0 Supported for interfaces and delegate types "Statically checked definition-site variance" Value types are always invariant Ref and out parameters need invariant type *Some of the interfaces in the .NET Framework are using this new feature. Beyond C# 4.0 Meda-data programming Support for domain specific languages *We need a compiler that isn't just a black box. Example: CSharpEvaluator ev = new CSharpEvaluator (); ev.Add("System"); ev.Eval("int Sqr(int x) { return x * x; }"); *Anders Hejlsberg shows a couple of very, very impressive demo's. Incredible!

| Notes from PDC Session: Extending SharePoint Online ... A waste of time, terrible session, no news, no knowledge by the presentor. Didn't give a good feeling on the SharePoint Online platform itself. Sorry to be so hard. I took some notes, and augmented it with some of my own thoughts and information. ------- SharePoint Online provides: Managed Services on the net - No server deployment needed, just a few clicks to bring your instance up and running - Unified admin center for online services - Single sign on system, no federated active directory yet Enterprise class Reliability - Good uptime - Anti virus -... SharePoint online is available in two tastes: standard (hosted in the cloud) and dedicated (on premises) Standard is most interesting I think: minimum of 5 seats, max 1TB storage. On standard we have no custom code deployment, so we need to be inventive! SharePoint Online is a subset of the standard SharePoint product (extensive slide on this in the slide deck, no access to that yet) SharePoint online is for intranet, not for anonymous internet publishing. $15 for the complete suite: Exchange, SharePoint, SharePoint, Office Live Meeting. Separate parts are a few dollars a piece. Base os SharePoint Online is MOSS, but just a subset of functionality is available. Also just the usual suspect set of site templates is available: blank, team, wiki, blog, meeting. SharePoint Online can be accessed through the Office apps, SharePoint designer and throuth the web services. SharePoint Designer: - No code WF - Customize content types - Design custom look and feel Silverlight: - talk to the web services of SharePoint online. - Uses authentication of current user accessing the page hosting the Silverlight control - See http://silverlight.net/forums/p/26453/92363.aspx for some discussion on getting a SharePoint web service call working Data View Web Part: - Consume data from a data source - Consume RSS feeds through http GET - Consume http data through HTTP GET/POST - Consume web services - ... - Configure filter, order, paging etc. - Select columns, rename columns, ... - Result is an XSLT file This XSLT code can be modified at will. There are infinite formatting capabilities with XSLT. Also a set of powerful XSLT extension functions is available in the ddwrt namespace (See http://msdn.microsoft.com/en-us/library/aa505323.aspx for a SharePoint 2003 article on this function set, see reflector for additional functions in the 2007 version;-)). See http://www.tonstegeman.com/Blog/Lists/Posts/Post.aspx?ID=85 for writing XSLT extension functions when you are able to deploy code, so not for the online scenario; this was not possible on SharePoint 2003). Note that the Data View Web Part can only be constructed with SharePoint designer. InfoPath client: custom forms for workflows Web services: Can be used from custom apps (command line, win forms, ...), but also from Silverlight to have functionality that is hosted in your SharePoint Online site itself. You can also host cus |
