Combobox change

[LeBlatt]

I have a combobox whose list is populated from a database, and i want that everytime the user selects an item in the combobox, it modifies the recordsource of an adodc.
I set the combobox style to 2 (dropdownlist) because I dont want the user to alter its value.

The problem is that the Change event is never triggered, so how do I know the user selected an item. I thought of using a timer and checking periodically, but there must be a simple way !

Thx for help !

[edit] I know Validate is triggered when one leaves the control, but want the display to be refreshed even if the user doesnt leave the combo, like just hitting the up/down arrows. Example of this is in the windows display properties, when you select a screen saver, it displays it immediately.[/edit]
