title: Can't get fullpath from fileUpload control asp.net
body: <p>I have a fileUpload and hidden field at aspx file.</p>
  
  <pre><code>&lt;asp:FileUpload ID="fuID" runat="server" ToolTip="Select Only Excel File"  /&gt;
  
  &lt;asp:Button runat="server" ID="btnUl" OnClientClick="document.getElementById('myHiddenInput').value =
  document.getElementById('fuID').value" OnClick="btnUlClick" Text="Upload" /&gt;
  
  &lt;asp:HiddenField id="myHiddenInput" runat="server" /&gt;
  </code></pre>
  
  <p>When I use this code for get fullpath:</p>
  
  <pre><code>string abc = myHiddenInput.Value;//Show fullpath
  string filepath =null;
  if(fuID.HasFile)
  filepath = fuID.PostedFile.FileName.ToString();//Show fullpath
  </code></pre>
  
  <p>All of these code show fullPath when I use IE.But when I use FF,It didn't show fullPath,Just show FileName from FileUpload.Anybody help me?Thanks,</p>
