title: Firing server side validations on moving from one page to another in Asp.NEt
body: <p>I need to fire certain server side validation for a page when the user is trying move from that page to another..</p>
  
  <p>Even though he is not clicking on any buttons these server side validations have to be fired when he is moving out of this page.. </p>
  
  <p>Could you please help me how to handle this.. Required field validations will not happen as the user is entering the page and leaving the page without doing any action in the page.. </p>
