title: Splitview content property windows universal
body: <p>Im including the splitview in my app. But <strong>i dont know how to fill the content of my splitview</strong>. I read i should nest the frame in there. So i have my Mainpage.xaml, and if the user clicks one menue button the content of the splitview should be for example helpandabout.xaml. Or <strong>what should i nest in the content property? And how do i replace the content with different pages.</strong> 
  I currently just tried to change the visibility of grids if the user presses one button but thats not the philosophy behind this control.
  Like this:</p>
  
  <pre><code>&lt;Grid x:Name="Grid1" Visibility="Visible"&gt; &lt;/Grid&gt;
  &lt;Grid Visibility="Collapsed" x:Name="Grid2"&gt; &lt;/Grid&gt;
  </code></pre>
  
  <p>And than the user presses a button at the splitview pane and the code does this:</p>
  
  <pre><code>Grid1.Visibility = Visibility.Collapsed;
  Grid2.Visibility = Visibility.Visible;
  </code></pre>
  
  <p>And i know thats a silly code piece. </p>
