>Is there an event/method to call or a property to set in order to programmatically open a combobox? I can't seem to find one. I would think calling the click() or downclick() method would work, but nothing happens.
David,

Calling the click or mousedown does NOT make a click, it just runs the code there.

To open a combobox on it getting focus you can put this code in the GotFocus();

DoDefault()
KEYBOARD "{DNARROW}"
NODEFAULT
