title: Xamarin Forms Navigation in Modal Page
body: <p>I have pushed a new <code>ModalPage</code> onto my current <code>NavigationPage</code> using <code>await Navigation.PushModalAsync(new ProfilePage());</code> I cannot figure out how to create a <code>NavigationPage</code> inside the <code>ModalPage</code>.  I want to load another page, wrapping inside a <code>NavigationPage</code> so that the loaded page has a navigation bar and back button to be able to return to the <code>ModalPage</code> (ProfilePage).</p>
  
  <p>I am trying to achieve:</p>
  
  <blockquote>
    <p>NavigationPage > ModalPage > New NavigationPage</p>
  </blockquote>
  
  <p>I have tried creating a new <code>NavigationPage</code> inside the <code>ModalPage</code> and pushing the new page onto the <code>NavigationPage</code> but nothing happens. e.g.</p>
  
  <pre><code>var navigationPage = new NavigationPage(this);
  navigationPage.PushAsync(new Page());
  </code></pre>
  
  <p>Can anyone help?</p>
