  Hi Arvin,
  
  You could track the changes in the rating by handling the OnClientRated event. In there you can check if the old value is 1 and the new value is 1 again, then you can force the value to 0. Here is a sample handler method to accomplish this:

  function unrateOnFirstStar(rating, args) {

      if(args.get_oldValue() == 1 && rating.get_value() == 1)

          rating.set_value(0);

  }

  
  Hope this helps.
  
  All the best,
  Niko

  Ok for the client... but If I want use in a server side code ?
  
  I have 3 state and I want use only two star.. 0 and 1  and 2.
  When I click on a star I must enter in a function server side.
  
  Is it possible ?

  Hello Lupotana,
  
    Even though the solution is on the client-side, it should work just fine with a RadRating control that is set to autopostback, because the client-side event handler will be called just before the page is being sent to the server.
  Still if you wish to completely escape the client-side code, then you will need to have a way to persist the old value of the RadRating control on the server side and in the OnRate event handler you need to make the same checks and assignments as in the client-side approach.
  
  Hope this helps.
