Your explanation isn't clear. Does this refer to a single combobox?.
<hr> I needed the combo box to have the first area selected as default.<hr>If the "area" is in the combobox and you have already made a selection, then the request doesn't appear to make sense. And by the way, client/user requests need to be questioned closely. If you don't understand why they need it that way, you're liable to spend a great deal of time on something that could be accomplished quite simply by using a different approach.
