We are not aware of such problem and you are the first one to report it. I tried to reproduce it locally but to no avail. Could you please provide more detailed information on the specific scenario?
Which version of RadControls for ASP.NET AJAX and .NET Framework are used in the application?
Are there any JavaScript errors thrown on the page? If so, could you please provide the exact error message?
Could you please provide a simple fully runnable project reproducing the problem so we can investigate it further?
For your convenience I have attached my test page, could you please modify it to a point where the problem occurs and send it back?
Regards,
Dobromir
