The Slackers have been busy !
Check out the Open Source project on CodePlex.
http://www.codeplex.com/AjaxDataControls/
Not only is there a controls library and all the source code for the controls but a RICH set of demos that illustrate utilization.
I’m now using them in my own projects.
Check ‘em out !
Great to hear that you are using them in your projects. We (the DNS/ADC team) are very keen to make sure that they become the #1 Ajax Data Controls for ASP.NET
