I'm trying to use a gridview within an updatepanel on an umbraco tabview and I keep getting the following error:
Cannot unregister UpdatePanel with ID 'ContactsGridUpdatePanel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported. Parameter name: updatePanel
