Just guesses without seeing code:

This happens when you close the form, right? In my programs, I check the
dataset attached to the grid to check for changes when the Close (or
isCLosing or whatever) event fires.

Could you be explicitly disposing of the grid before performing this check?
I do not think you need to call grid.dispose. If not, then you may have
control event handlers doing more than is safe to do when they are fired.

Just guesses.
