JavaScript class browser: once again with jQuery
I’ve already posted twice about that little class browser application. The first iteration was mostly declarative and can be found here: http://weblogs.asp.net/bleroy/archive/2009/09/14/building-a-class-browser-with-microsoft-ajax-4-0-preview-5.aspx The...
How to render the same template on the server and client with minimal redundancy
Last week, I wrote a post about how the new Microsoft Ajax Library Preview 6 made it a lot easier to write unobtrusive and imperative data-driven applications . Because for the previous preview, I had written a cool little class browser using a declarative...
Entirely unobtrusive and imperative templates with Microsoft Ajax Library Preview 6
Today is the release of the sixth preview of Microsoft Ajax Library. Don’t get fooled by the somewhat silly and long name: this is a major release in many ways. The scripts have been majorly refactored since preview 5. Check out the other posts out there...

Why is ASP.NET encoding &’s in script URLs? A tale of looking at entirely the wrong place for a cause to a non-existing bug.
Several people have reported seeing errors in their logs that seem to be due to requests such as this: /ScriptResource.axd?d= [lots of junk] &amp; t=ffffffffee24147c The important part here is the HTML-encoded “&amp;” sequence, which stands for...
Survey: Ajax usage among .NET developers
If you haven’t already and you are a .NET developer, please take a couple minutes and answer this survey, whether you use Ajax or not. There are a number of Ajax surveys around, but Simone’s is the only one that focuses on .NET developers. The survey...
setInterval is (moderately) evil
JavaScript has two ways of delaying execution of code: setInterval and setTimeout . Both take a function or a string as the first parameter, and a number of milliseconds as the second parameter. The only difference is that the code provided to setInterval...
New release of the Ajax Control Toolkit
A new version of the AJAX Control Toolkit is now available for download from the CodePlex website. It contains three new controls: HTMLEditor - allows you to easily create and edit HTML content. You can edit in WYSIWYG mode or in HTML source mode. The...
