title: Populate asp:FileUpload from code behind
body: <p>Is it possible to populate <code>asp:FileUpload</code> from code behind?</p>
  
  <p>I have a search form which user can populate using <code>upload_default_parameters()</code> method and therefore I also want to populate the fileUpload control from code-behind with a file on server if user opt to use the default parameters.</p>
