We are migrating a web applicatin from vs05 to vs08. This application is using Telerik web controls. After I converted the project, and run, I get the exception: "A control is already associated with the element". I traced it down to a use control that has Telerik RadCombo box on it. However, I don't see anything out of place. Researching it, hasn't gotten me any results. I would appreciate any pointers.

Thanks!

Could you show the code that throws the Exception?

A: 

Search for the ID of the problematic combo box in your solution and see where it is used. If you have not set an ID attribute for the control - do so and make sure it is unique.

If you are using AJAX requests make sure that you are updating all controls that need to be updated after AJAX.
