Checkbox – DATAREPEATER Control

Hi,
I have put a checkbox on a UserControl, and bound it to a DataRepeater on a Form. When I run it, it looks fine, just what I want to see…Each record with a checkbox next to it…..EXCEPT, that when one record loses focus, if I click the checkbox, it clears when I move to another record…………I guess I’m looking for the ability to ‘multi-select’ (ea checkbox) and then update the recordset… Please help…TIA!
