title: Page pop up in asp.net c#
body: <p>I am doing a pop up on my home page using the following link</p>
  
  <pre><code>&lt;a href="CreateUser.aspx" target="_blank"
  
   onclick="window.open('CreateUser.aspx', 'windowname',
  
  'width=500,height=400,toolbar=no,status=no,menubar=no,scrollbars=no,resizable=no,directories=no,location=no'); return false"&gt;Create users&lt;/a&gt;
  </code></pre>
  
  <p>But when this window is opened I am able to navigate in the home page, which I want to disable until user clicks ok or cancel in the create users page. How to do that.</p>
