With the CheckListBox in VB.NET in VS2005, how would you make it compulsory that at least one item is selected?

Can you select one of the items at design time to make it the default?

EDIT: How can I make it so the last item the user tries to uncheck is the one that stays checked? So it's like the user tries to uncheck the only checked item but can't because it checks back straightaway.
