I have a couple radio button groups in my Windows Form that I would like to bind to a data table.

When I query the database for a single record, I just grabbed row zero and used if-else to select the one i wanted.

Unfortunately, when I get multiple records, I can't do that.

I'm not sure which property should be bound to make it select the right button based on current record.

Are you saying that when you change rows, you want to know how to set the radio buttons to have the correct one checked ?
The BindingSource has an event for position change. Setup a BindingSource for this table, and attach an event handler to its PositionChanged event.
