this exception usually occurs in a multithreaded situation. A Paint() occurs on the gridcontrol. This causes a Paint() do be applied to the subelements. If one of these visual elements is deleted before the paint is completed, this is the exception you will get.
This is not supposed to happen in a single thread application unless you are altering your data source.
If you can send a sample application to us (as a zip archive) that reproduces the issue, we will be able to investigate.
