Can I limit a CheckboxList to single selection?

[millerk]

I have a db search page that gives the option of doing a "sounds-like" search. There are 2 types of sounds-like they can pick from, but I also want them to be able to pick neither.
So ideally, I'd like 2 checkboxes and I'd like the user to be able to select one or the other or neither.
Is this possible, or do I need to use a radiobuttonlist instead and add a 3rd radiobutton for "none"?

This a perfect application for using a RadioButtonList. Chekboxlists are for multiple selections, RadioButtonList, only one selection.
