title: How to get content from another page in uwp after a few seconds
body: <p>I have Page1.xaml</p>
  
  <pre><code>&lt;Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"&gt;
      &lt;StackPanel HorizontalAlignment="Left" Height="720" VerticalAlignment="Top" Width="575"&gt;
  
          &lt;TextBlock Foreground="White" TextWrapping="Wrap" Margin="28,20,31,0" FontSize="14" Height="145"&gt;
              &lt;TextBlock.Transitions&gt;
                  &lt;TransitionCollection&gt;
                      &lt;EntranceThemeTransition FromHorizontalOffset="400"/&gt;
                  &lt;/TransitionCollection&gt;
              &lt;/TextBlock.Transitions&gt;
              &lt;Run Text="Text 1"/&gt;
          &lt;/TextBlock&gt;
      &lt;/StackPanel&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p></p>
  
  <p>And Page2.xaml</p>
  
  <pre><code> &lt;Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"&gt;
      &lt;TextBlock Foreground="White SelectionChanged="TextBlock_SelectionChanged" 
  Name="TextBlockOne"&gt;
          &lt;TextBlock.Transitions&gt;
              &lt;TransitionCollection&gt;
                  &lt;EntranceThemeTransition FromHorizontalOffset="400"/&gt;
              &lt;/TransitionCollection&gt;
          &lt;/TextBlock.Transitions&gt;
          &lt;Run Text="Text 2"/&gt;
      &lt;/TextBlock&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>What I want to do is to replace "Text 1" in page 1 after 5 seconds with "Text 2" from Page 2.</p>
  
  <p>I tried this in Page2.xaml.cs:</p>
  
  <pre><code>private void TextBlock_SelectionChanged(object sender, RoutedEventArgs e)
      {
          var test = TextBlockOne.Text;
          Frame.Navigate(typeof(Page1), test);
      }
  </code></pre>
  
  <p>How do I solve this problem?</p>
