title: xamarin.forms How to refresh a contentview and contentpage?
body: <p>I have <code>ContentView</code> in <code>CarouselPage</code>. I navigate to <code>ConentPage</code> from <code>ContentView</code>. Update <code>ContentPage</code> and return back to <code>ContentView</code>.</p>
  
  <p>Now, on this note, my <code>ContentView</code> not get updated. </p>
  
  <p>Also If I change text in entry in <code>ContentView</code>and go to <code>ContentPage</code>and return back, my change in entry is erased.</p>
  
  <p>So, Is there any mechanism so that when I get back to <code>ContentView</code> it get refresh ?</p>
  
  <p>I tried using <code>OnAppearing()</code>method in <code>ContentView</code> but it shows error like <code>ContentView does not contain definition for OnAppearing()</code>.</p>
  
  <p>Thank you. :)</p>
