Cetin's answer (using the button's parent property to walk up the hierarchy tree) is correct of course. Another, OO, approach would be to decouple the two object and let the container handle a message from the command button. So, instead of the command button talking directly to the grid, it would talk to the container, and the container would be responsible for passing the message along.
