title: Visual Studio 2010 designer not displaying AJAX tab container correctly
body: <p><strong>OverView</strong></p>
  
  <p>I'm having problem with Ajax Tab Container ,I have added three tabs in it namely "Add User" , "Delete User" and "Update User". I had to add them using "Source View" ,because I was unable to find the smart tag of Ajax Tab Container.</p>
  
  <ul>
  <li>I can't modify tabs,</li>
  <li>Can't add event handlers,</li>
  </ul>
  
  <p><strong>Problem</strong><br/>
  So the problem is Visual Studio 2010 is not displaying AJAX tab container correctly in the designer and I have to manually modify the control in the "Source View" which is time consuming.<br/><br/>
