I tried to reproduce the problem with the provided information but to no avail. Could you please provide more details on the specific scenario?
- Which versions of RadControls, AjaxControlsToolkit and .NET Framework are used in the application?
- Under which browser and its version the problem occurs?
- Could you please provide sample fully runnable project reproducing the problem so we can examine and debug it locally?
For your convenience I have attached my test page, could you please modify it to the point where the problem occurs and send it back? For my test I used the latest versions of RadControls for ASP.NET AJAX (2012.2.607) and AjaxControlsToolkit (4.1.60501).
All the best,
the Telerik team
