title: Auto refresh Updatepanel every 5 seconds
body: <p>I have an update panel in my master page in a <strong>webforms</strong> application, now I have set this update panel to refresh every 5 seconds so as to reflect an updated count of row items. Some thing like the number of new messages. My questions are:</p>
  
  <ul>
  <li>Is this the right way to reflect for new row item count on my page every 5 seconds and   </li>
  <li>Will this degrade my applications performance in the long run in what
  ever way by constantly refreshing the update panel frequetly. </li>
  </ul>
  
  <p>My label is getting its value from an <code>ExecuteReader</code> query from my code-behind.</p>
