I am using RadControls version Q2 2012. The RadTextBox generates a NullReferenceException when I try to paste something and this behavior is shown in IE 10 only. RadTextBox works fine in MF and Chrome. How to resolve this?
This is a bug which has been fixed in the Q3 2012 SP2 version of Telerik RadControls for ASP.NET AJAX. Please upgrade your RadControls to the latest version.
