Another question. I would like to be able to set/kill a timer for any cell in a Grid. My paradigm is:
 
1. Get the focus for a cell (_GotFocus()) & set the timer
2. Honor the timeout if the event is present & kill the timer, or
3. Lose focus for a cell (_LostFocus()) & kill the timer.
 
But, I can't find a way to get the focus for a cell, only for the grid. There is no associated _GotFocus(), _LostFocus() for cells. Am I missing something?
 
Background. With the capability to associate a timer with a cell, I can simulate tooltips and present the user with help. In particular, help associated with a fixed cell (intersection of a fixed row and a fixed column) allows generic help on an input field.
