Unhandle exception
posted

Hi!

I'm using the ultraDockManager and inside of one of the panes I have an ultraGrid in which i load information via datasource. when i'm in debugging the app there is an exception that says I have an  unhandled exception (I've attached the error), or sometimes the information disappear from the grid (the error doesn't have a behavior pattern).. I have checked all the events and variables that can cause this problem but I haven't found anything.

thnx

    Hi,

    The big red X you have in your screen shot here indicates that an exception occurred while the control was painting (in the OnPaint event).

    This can happen if there's a bug in the grid, but since the grid has been around for such a long time, now, most of those kinds of errors have been fixed for a long time.

    So the most common cause of exceptions like this in more recent versions of the grid is threading issues.

    Is the exception the same every time?

    Is you application using multiple threads?

    It also might help if you specified what version of the grid you are using and posted the text of the call stack of the exception.
