You have to add in place (+=) to the specific event you want to handle. 
If you want to watch a 'list' (of some sort) and perform an action on 
the combobox you will need to listen for an event on the list.

What specific class is the list you intend to use? If you find the MSDN 
documentation for that class it will show you all the events available.
