A useful control to add to the toolkit would be a ComboBox that is extended to allow mutliple columns. The combobox works well as is; but, the next step would be to extend it to allow multiple columns. I suppose that is like suggesting to create a gridview that looks like a combo box; so, why not just use a gridview. The reason is space, appearance, and function--say if you only want one column to show when inactive, expand out to multiple columns when active, and only to allow selecting items in the list. So where would this be useful? Perhaps the most useful case would be for an order list type application where the user chooses items based on the product name. When active the control would show additional information for each product such as product description and status (whether it is in stock).
