title: Return a razor view into an Iframe
body: <p>I create a small form and give the link to my customer so he include the view in one <code>IFRAME</code> in his page and show ok.</p>
  
  <p>When user submit the <code>IFRAME</code> form instead of redraw inside the <code>IFRAME</code> take the whole page.</p>
  
  <pre><code>...
  ViewBag.result = "Form send correctly";
  return View();
  </code></pre>
  
  <p>What should I use instead  <code>return View();</code> ?</p>
