Correct.  The data is not written to the table until the editor is 
dismissed, because up until that time the user can cancel by pressing

Yep, just do what would normally be done when the cell editor is 
dismissed.  Something like this IIRC:

	if thegrid.IsCellEditControlShown():
		thegrid.SaveEditControlValue()
		thegrid.HideCellEditControl()
