title: Multiple update panels and multiple postbacks cause entire page to refresh
body: <p>I'm having the <a href="https://stackoverflow.com/questions/2627339/async-trigger-for-an-update-panel-refreshes-entire-page-when-triggering-too-much">same problem I had yesterday</a>... The solution Aristos provided helped solve the problem, but I have other places sending updatepanel postbacks causing the same problem. </p>
  
  <p>When an update panel is updated and another request for an update is called before it has a chance to render the first updates, the entire page refreshes instead of just the update panel.</p>
  
  <p>I used <a href="http://www.fiddler2.com/fiddler2/" rel="nofollow noreferrer">fiddler</a> to see what was going on and here's what happens... If I wait for the request to return before doing another request I get this:</p>
  
  <blockquote>
    <p>21443|updatePanel|dnn_ctr1107_CRM_SalesTool_LeadsUpdatePanel|</p>
  </blockquote>
  
  <p>But if I don't wait, I get this:</p>
  
  <blockquote>
    <p>66|pageRedirect||<a href="http://mysite.com/salesdashboard.aspx|" rel="nofollow noreferrer">http://mysite.com/salesdashboard.aspx|</a></p>
  </blockquote>
  
  <p>The code from the <a href="https://stackoverflow.com/questions/2627339/async-trigger-for-an-update-panel-refreshes-entire-page-when-triggering-too-much">previous question</a> is still the same except I added <code>UpdateMode="Conditional"</code> to the update panel.</p>
  
  <p>Any ideas? Or is the only solution to this making sure that 2+ updates for any number of update panels (as long as they're on the same page) never happen?</p>
  
  <p>Thanks,<br/>
