Firstly, such code is better placed in Combo1.InteractiveChange event. If you want to populate second combo from Form.Init event, you call it directly from there: This.Combo1.InteractiveChange().
There are few more problems: it's better to populate combo from cursor, you need to fire Combo.Requery after each SQL, etc.
