Hi,I recently upgraded Infragistics from 2007.3 to 2011.2. When user did copy one cell and drag the rest of cells in same column to paste , the new version 11.2 throws exception when the mouse is out of grid. Do we treat the drag event differently in new version? Did anyone has same problem? Thanks.

I think this might be a known bug that is already fixed. Try getting the latest service release and the problem should be corrected:

We don't allow to get latest service ourselves due to company's policy. I used 11.2.20112.2050 right now. Do you have any temporary solution? Just adding error handling in some event (cannot figure out which event ) to ignore this error? Thanks.
