Random crashes in UltraWinGrid
posted

We use version 10.1.20101.2027. This happens occasionally when the user closes a window and the dispose method is called. I see there has been reported something similar with the UltraWinToolbars in this thread: http://forums.infragistics.com/forums/p/41053/236401.aspx#236401.

The stack trace follows bellow:

    The original issue affected the drawing of all of the Infragistics WinForms controls, but it should be fixed in the version you listed here. Are you absolutely certain that you are using that version when you get this exception?

    If so, then there must still be some outstanding issue here. But that seems very unlikely and I'm not sure what we could do about this without a sample with which to duplicate the error.
