I wish to alter one behavior of a combobox (2 - Dropdown List) in a grid. Here it is:

1) If the *mouse* moves the focus to the combobox I want to prevent the dropdown list from immediately appearing. I just want the control receive focus. Thereafter, as long as focus remains on the cell, subsequent mouse clicks should yield the default dropdown list behavior.

2) However, if the combobox got its focus from the *keyboard*, the very first mouse click should open the dropdown list.

I have been able to achieve the first behavior but not, simultaneously, the second. I really hope someone else has worked on this one and would be kind enough to share with me what I'm surely overlooking. Thanks so much!
