Thread: Combobox that doesn't drop down

I'm trying to use comboboxes, but I'm having a hard time to get it to work just right.

I'm using a combo box with the drop-down property, it's not a simple combobox. In my code, I add strings to the combo box, but not data. When I click the arrow that is supposed to make the list box container drop down, it's empty. However, when I use the arrow keys, I can select the strings that I added to the combo box as well as their indexes.

So I'm pretty sure it's a problem with the actual list box of the combo box control, and I've tried almost everything I can think of, but I can't seem to find the problem.

Anyone have any ideas?

Thanks in advance,
Chris
