title: Label null exception
body: <p>I am receiving a null exception every time I try to send the <code>HttpContext.Current.User.Identity.Name</code> to the label.  Any ideas why?</p>
  
  <p>This is what im using.</p>
  
  <pre><code>String Utilizador = Page.User.Identity.Name;
  
  Response.Write(Utilizador);
  
  Label1.Text = Utilizador;
  </code></pre>
