title: Databinding of RadioButtonList using SelectedValue...possible?
body: <p>I am databinding a GridView to an object datasource.  The gridview contains a TemplateField which contains a RadioButtonList with ListItems defined inline.<br>
  I want to be able to databind the SelectedValue of the RadioButtonList to the same underlying table as the other grid columns, but it doesn't work!  </p>
  
  <p>Do I have my syntax wrong, or is this impossible and requires looping code to individually select the proper item in each row?</p>
