    I don't think the error you are receiving is caused by our RadDropDownList control. Switch the control to an ordinary ASP.DropDownList control and see if the issue disappears.


    Check out the Telerik Platform - the only platform that combines a rich set of UI tools with powerful cloud services to develop web, hybrid and native mobile apps.
