title: How do you force Visual Studio to regenerate the .designer files for aspx/ascx files?
body: <p>Sometimes when I'm editing page or control the .designer files stop being updated with the new controls I'm putting on the page.  I'm not sure what's causing this to happen, but I'm wondering if there's any way of forcing Visual Studio to regenerate the .designer file.  I'm using Visual Studio 2008</p>
  
  <p><strong>EDIT:</strong> Sorry I should have noted I've already tried:</p>
  
  <ul>
  <li>Closing &amp; re-opening all the files &amp; Visual Studio</li>
  <li>Making a change to a runat="server" control on the page</li>
  <li>Deleting &amp; re-adding the page directive</li>
  </ul>
