Jerry,

There was a thread about this topic, Incremental Search or Auto-Complete (whichever you prefer to call it), several months ago. Cathi posted this link: http://www.codeproject.com/vb/net/autocomplete_combobox.asp
Apparently this isn't intended for the DropDownStyle of DropDownList (I haven't really studied the code), but I'm sure that looking at the example will give you ideas of how to hack it to make it work with a DropDownList type of combo.
