Einar,

One solution is to create some events in your ComboBox sub-class (you *have* subclassed your controls, I hope). Create a BeforeSelectedIndexChanged event (and, while you're at it, you might as well create an AfterSelectedIndexChanged event also). Basically, you'd need some code in some of the mouse events and keydown/up events to properly fire the Before and After events. We've done it with a ListView, but not with a Combo ... should be somewhat similar, so I'm sure it's do-able.

Just some food for thought ...
