title: Uncheck all checkboxes in repeater except checkbox being checked
body: <p>I know my question reads a bit like that 'how much wood can a woodchuck chuck' line, please excuse that...</p>
  
  <p>I have a repeater with checkboxes.  There are numerous rows in this repeater - I never know how many - I want only one checkbox checked at any time. If the user changes the checked checkbox, any pre-existing checks are unchecked therefore maintaining a single checked checkbox.</p>
  
  <p>I am using VB, but comfortable to port any C#. I want to use JQuery.  I have been looking on Google, but only ever seem to find ALL checked, ALL unchecked systems.</p>
  
  <p>Any suggestions?</p>
