>endifSince I just cut&paste you should play with it some (ie: contains a custom prop ref to freetable). In init related database is opened if not (-if not free-)and freetable is set. It's bypassed with mouse clicks of course. It's an old code and not revised yet. You can extend it for your needs. BTW: it's in beforerowcolchange.

ok. We'll wait for a visual foxpro method that tell us when the user want to move to another record in a grid by clicking on it. Thanks
