Hello,

I am doing server side sorting with RadGridView, and I have noticed that with the latest internal builds I get "Unable to cast" exception.

Here is my scenario:

I have 74 columns, my grid is bound to a IEnumerable (two way binding).

At first, if I try sort, all is well, but if I try to scroll horizontally, and then do sort, I get this exception:

Message: Specified cast is not valid.

I have noticed this problem in Version 2009.3.1208.1030, and a problem still exists in Version 2009.3.1219.1030.
