Hi,

I am using  RadGrid (Q2 2009 build) . I am getting this error when trying to expand or collapse in IE7.

"Microsoft JScript runtime error: Sys.InvalidOperationException: A control is already associated with the element."

Basically, our page has a placeholder where we load user control programmatically. User control contains the radgrid.

If I remove RadAjaxmanager, it works fine but there is no ajax.

Please let me know how I should fix this.

Thanks

Hi Ra,

Based on the supplied information, it is hard to determine the cause of the issue.
To further trace its cause, it will be best if you open a formal support ticket, and send us a small working project, demonstrating your logic, and the unwanted behavior. We will review it locally, and get back to you with additional information.

Sincerely yours,
Yavor
