How can I put the cursor behind the number in editable cell?

[Kevin Yang]

The cursor has been put behind the text by the following code when the "CellEditStarting" event triggered:
((IntUpDown)e.Control).Select(e.Control.Text.Length, 0);

but after the user clicks on the up-arrow in the cell control, the cursor was put in front of the text again.

Is there any event triggered when user click on the up-arrow in the cell control? So that the cursor can be put behind the text again.
