Hi Ian,
Man oh man, I searched for an hour but only found vaguely related issues with a few hints that didn't work related to calling EndEdit() manually. The event you mention I think is only used by controls hosted inside a grid cell, which I've mercifully never needed to do. However, I'll re-read the bits about that event and see if I can use it from the grid's parent code. I'm guessing therefore that the behaviour I'm seeing is a bug in the DataGridView control, but I've seen no specific evidence of that yet (or no one is owning up to it).

Then, assign it to checkbox variable at class level, and handle the actual checkchange event. All of which sounds very awkward and I haven't tried this for yonks, so it may be wrong. I searched briefly and it seems like your problem is well-known. One hit gave something like the above description. _____ Ian Thomas Victoria Park, Western Australia
