Solution 1

Handle the OnFocus (or whatever the event is called) event for the tab in question, and from that event handler, cause the dropdown to expand.

If I remember correctly, set the combobox's DroppedDown property to true.

If you are after the drop-down being shown automatically then I would have a read of this
