The only way you can do this is to create your own custom control that's derived from the .Net combobox.

EDIT ===================

Can I elaborate? Yeah - google is your friend. The process and art of writing a custom control is WAY beyond the scope of a "quick answer". You have to understand pretty much everything there is to know about how a control works, and how to change it to do what you want. It's not an easy task, and even the most experienced programmers flinch a little at the prospect. If you look around (using google), you might find a custom combobox that already does what you want.

To be honest, it'll probably be a lot more trouble than it's worth.

You would have to create a custom control based on a ComboBox, and trap the windows message CB_GETDROPPEDCONTROLRECT[^] to return a different rectangle - i.e. above the control rather than below.

I've never tried it - never wanted to, nor do I now - but it should work.

Good luck!
