If I have some rows activation set to disable and the drop down is not showing. I can down and up arrow and the disabled items are skipped. If I use the wheel mouse it selects the row even if the row is disabled. Unlike most of the posts I have read I don't want to disable the wheel mouse I just want it to act like the up and down arrow does.

I have attached a small sample that should replicate the issue described above. When I down or up arrow a row set to activation Disabled never fires the row selected event. When I use the mouse wheel it does.

Any suggestions on how I can prevent this?
