title: FileUpload control inside an UpdatePanel without refreshing the whole page?
body: <p>According to <a href="http://msdn.microsoft.com/en-us/library/bb386454.aspx" rel="noreferrer">Microsoft</a> the FileUpload control is not compatible with an AJAX UpdatePanel. </p>
  
  <p>I am aware that a PostBackTrigger can be added to the submit button of the form like this:</p>
  
  <pre><code>&lt;Triggers&gt;
    &lt;asp:PostBackTrigger ControlID="Button1" /&gt;
  &lt;/Triggers&gt;
  </code></pre>
  
  <p>The problem is that this forces the form to perform a full post-back which voids out the whole point of using the UpdatePanel in the first place. Is there a workaround to this issue that does not cause the whole page to refresh?</p>
