>How you break down your business objects would depend on a number of issues. Personally, I try to keep the number of business objects down to a minimum. Perhaps you could instance one object dedicated to validation rules at the time the app is run and keep it in memory.

Then have the business object fire validation for each control that has been flagged when saving?
