Hi Rana ,

From the stack trace of the exception you provided it seems that the error is generated by your custom extender control (there is no Telerik.Web.UI namespace reference). Can you please check whether my assumption is correct? Additionally, you may try moving merely our controls in another user control to see whether this makes a difference.

General guidelines how to use our controls under MOSS you can find in this section of the documentation:
