Hello Venu,

I made a simplified version of your code scenario. I have one WebUserControl with RadGrid in it and I added this control in a PlaceHolder inside an ASP:GridView. Here the events are firing for this grid, and code inside the radGridCourseInfo_ItemCommand is successfully executed.

Please see the attachment and let me know what differs in your case.

May be the way i am binding radgrid inside the webuser control. Please see the code for the user control i am using.

i was reading some online form, and foud the advance data binding some times creates this kind of issues if we do not use it properly.

Hi Venu Daroju,

You user controls look fine, although I cannot test it without the additional classes used.
The problem may occur because of loading the control at runtime. Please read this help article for more information.
