I have a custom control that has a series of comboboxes. In my application, I programmatically add the control to several programmatically created tabs. When the first combobox value is changed, I would like to iterate through each of the controls and set their value to match. I know how to iterate through the tabs and find a particular combobox within each control, but I haven't been able to figure out how to assign an event to those comboboxes to trigger the search in the first place.

How does one assign an even to a subcontrol within a custom control?
