title: give the ID as a custom attribute to checkbox in a grid for manual update
body: <p>I like to update just the value of my checkbox in a asp grid.</p>
  
  <p>so i thought i bind the id to the checkbox ( but how?) and fire an update in code behind by clicking the checkbox.</p>
  
  <p>but how can I get the ID, and where I have to bind this id to get it in code behind in the event?</p>
  
  <p>Thanks</p>
