Which Property/Method of a ComboBox can I use to detect whether the user has changed the DisplayValue of a Combo Box (Style 2) via the Mouse as opposed to Keying in via the Keyboard. My Intention is to make the Cursor move to the next object (in Tab Order) when the User Drops down the ComboBox and clicks on any of the items on the list. By Defailt the cursor remains in the Combo Box till moved out by clicking elsewhere or by pressing a Cursor Movement Key such as ENTER, TAB etc.
