Hi Team

I am using the 2010.3.1317.35 version of telerik rad control for Asp.net ajax.
The following is the code for default.aspx and detault.aspx.cs file.
When i type in for search on the basis of input the itemrequest event is not firing in IE 9 browser.

Aspx Page code
default.aspx

Hello,

I have tested the scenario in question with the version specified and everything works as expected -- the OnItemsRequested event is fired as it should.
Attached is the website I have tested. You could download it and test it locally. Does it work at your side?

If you are still having troubles, could you record a video so we would be able to see what exactly happens when the OnItemsRequested event is called?
