Sometimes, I got the following exception from RadGridView when I scroll over the RadGridView using mouse. Could anyone help me on this problem? Thanks a lot!

Exception:

System.NullReferenceException: [Arg_NullReferenceException]

Arguments:

Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=4.0.60310.0&File=mscorlib.dll&Key=Arg_NullReferenceException
