I received Telerik’s monthly newsletter this morning and noticed that they’ve added support for ASP.NET MVC to their AjaxControls. Now they’ve taken it a step further to produce an MVC forums application using their control suite. If you are a Telerik subscriber, you can download their demo application from their website.
I came across a postback issue while using the CascadingDropDown AJAX control. I had a web page with 3 DropDownList controls. The data for these controls was populated from the CascadingDropDown which would bind the data at runtime.

If you have any suggestions, please pass them on. I’d prefer if they were submitted using the Issue Tracker on CodePlex.
