title: Twice postback in ASP.NET
body: <p>My page is fully postback twice. I am using master page with AJAX. The structure of master page is as follows.</p>
  
  <pre><code>+---------------------------------------------+
  
  |  Web User Control with AJAX Tab Control     |
  
  +---------------------------------------------+
  
  |        |                     |              |
  
  | Col1   | ContentPlaceHolder  |   Col3       |
  
  |        |                     |              |
  
  |        |                     |              |
  
  +---------------------------------------------+
  </code></pre>
  
  <p>The web user control contains the AJAX Tab Container with AutoPostback on.</p>
  
  <p>I have created several ASPX pages using this masterpage.</p>
  
  <p>The content place holder also gets a web user control depending upon page.</p>
  
  <p>Whenever I jump on a page by clicking on tab the page is fully postbacked twice. I dont understand whats the reason. That makes viewing reports cumbersome as it requires double time.</p>
