>>Hi everybody,
>>
>>I have a 3 comboboxes on a form. When I select value in combo1, I want to update combos2 and 3 to show only relevant values. Same thing for combo3 which is dependent on combo2.
>>
>>My question is - how should I name the method(s) that would re-populate my combo2 and 3?
>>
>>Thanks in advance.

>The name isn't really important, is it? For that matter you don't need to call other methods. You could issue the requeries of combos 2 and 3 in the combo 1 LostFocus. Changing the value of combo 1 is what actually triggered the requeries, so it seems like an appropriate place to do it.

You would definately want to setup methods to be called from within the combo1 method. Remember, each method should perform 1 function and return. Therefore, you need the method for combo1 and the methods for combo2 and 3. In OOPyou want to think "separation of concerns".
