title: Inject html from Action
body: <p>I'm trying to add an html string to the view from a different action (ideally from an event).</p>
  
  <p>I have an action that redirects to a different url.</p>
  
  <pre><code>return Redirect(redirectUrl);
  </code></pre>
  
  <p>I've tried adding to the content and registering as a script:</p>
  
  <pre><code>_orchardServices.WorkContext.Layout.Content.Add(htmlString);
  
  _resourceManager.Invoke().RegisterFootScript(htmlString);
  </code></pre>
  
  <p>Any suggestions?</p>
