ASP.NET AJAX (

After installing the iPhone 1.01 software update, iPhone users may notice that what used to be an asynchronous request from the browser is now a syncrhonous request. They may notice other symptoms of an underlying problems as well. The update changes the way regular expressions are processed by the Safari browser and adversely affects a regular expression used by the Microsoft AJAX Library for JSON serialization. An updated regular expression preserves the functionality and works with the new Safari behavior. The regular expression is in a script file served from the System.Web.Extensions.dll on the server by default. Here are the set of steps you can take to have the scripts served from the file system instead with an updated version compatible...
Jim Minatel from Wrox has arranged for an excerpt from the book to be made available online. It's a section titled Enabling Intenret Explorer for Debuggng ASP.NET authored by Dan Wahlin. You can check it out at: http://www.wrox.com/WileyCDA/Section/id-305946.html Read More...
Well, I've been asked three times now why I haven't blogged about my book, so here it is. I worked with Dan Wahlin and Wrox to create a book about ASP.NET AJAX. The book covers the UpdatePanel, ScriptManager and other server controls, discusses how the Microsoft AJAX Library works and how you can more easily invoke web services, provide client-side event handlers, debug and deploy your AJAX application and write custom AJAX controls. Check it out at Amazon Professional ASP.NET AJAX Professional ASP.NET AJAX here . Read More...
The release on Windows Update that contains updates to enable the validator controls to work with the UpdatePanel has been delayed. However, you can download a HotFix that contains the changes. http://connect.microsoft.com/VisualStudio/Downloads/DownloadDetails.aspx?DownloadID=6106 Read More...
I recently filmed an episode of the .NET Show with Brad Abrams ( http://blogs.msdn.com/brada/ ) and Bertrand Le Roy ( http://weblogs.asp.net/bleroy/ ). Brad asked for suggestions of words to work into the interview before we did it ( http://blogs.msdn.com/brada/archive/2007/02/16/filming-ajax-on-the-net-show.aspx ). I believe I won that challenge, but I can't be a participant and the judge as well. Thanks to Robert Hess and the rest of those that have been working on the .NET Show. Here is a link to the episode http://msdn.microsoft.com/theshow/episode.aspx?xml=theshow/en/episode062/manifest.xml . Read More...

ASP.NET AJAX provides new APIs for registering script with the ScriptManager. Using these APIs allows controls to work well with partial rendering. Without them, controls placed inside an UpdatePanel won't work as expected. In previous CTP releases of ASP.NET AJAX, we had a set of validator controls that derived from the v2.0 controls and used the new APIs. This made them work well with ASP.NET AJAX. WindowsUpdate will soon include a version of System.Web that can take advantage of the new APIs. So the new controls which would have been redundant have been removed. However, the update isn't available yet and ASP.NET AJAX has been released. So, in the short-term, the source code for a set of custom validator controls that work with partial rendering...
The ASP.NET AJAX Release Candidate is available here . A major change between beta2 and the RC is the switch from the Microsoft.Web.* namespace to the System.Web.* namespace. It's a straightforward update to exisiting code and should simplify things going forward into the next release of the .NET Framework. No other major changes are expected between now and the final release. At this point, we are only taking high priority fixes and will release before too much longer. If you encounter problems, please let us know. And thanks to those who have provided feedback so far. It has helped us prioritize our work and while we haven't been able to include everything we would like for this release, I do think we have a solid release coming and am looking...
Here is one of the samples I was asked for at TechEd last week. How to access session state data from the browser. There are two C# methods in the page. One overrides the the OnLoad method and stores a value in session state for demonstration purposes. The other is a static method decorated with the WebMethod attribute that can be called from JavaScript. It retrieves the value for the given key from session state. Currently, only static methods are callable use the PageMethods object in the browser. In the JavaScript code, there is a pageLoad method which will be called automatically by the ASP.NET AJAX script library. The PageMethods object is used to invoke the method on the server. It provides callbacks for success and error. The success...
Well, just a few short weeks and some very late nights after the first beta was released, we have released beta 2 of ASP.NET AJAX. There are three different pieces you can download: 1) ASP.NET AJAX Extensions beta 2 is available here . This is the core part of the ASP.NET AJAX offering and required for the other parts to work. It includes the Microsoft AJAX Library which is the JavaScript libraries that can be used in the browser for more easily writing maintainable object-oriented JavaScript code that interacts with the DOM. The Microsoft AJAX Library can be downloaded separately as a zip file here. 2) The ASP.NET AJAX 2.0 Futures November CTP is available here . This naming is a little different than what we have used before. This is a set...
