title: How do I navigate from my MainPage and refresh it?
body: <p>I navigate from my SecondPage to my MainPage like this:</p>
  
  <pre><code>private void HardwareButtons_BackPressed(object sender, BackPressedEventArgs e)
          {
              Frame rootFrame = Window.Current.Content as Frame;
  
              if (rootFrame != null &amp;&amp; rootFrame.CanGoBack)
              {
                  e.Handled = true;
                  rootFrame.GoBack();
              }
          }
  </code></pre>
  
  <p>but the aplications crashes because in my MainPage I have a <code>&lt;CaptureElement&gt;</code> that I need to refresh. So I want to know how to refresh my MainPage after I navigate to it.</p>
