    This kind of error ususally means something raised an exception during the Paint event of the grid. These are pretty hard to debug.

    I would suggest the following:

    1) Make sure you have the latest Hot Fix.

    2) Errors like this are often caused by multi-threading. If your application is using multiple threads, then you may need to check InvokeRequired and make sure you are not causing changes that go across threads without the proper marshalling.
