title: How to adapt the app to multiple resolution in Windows8
body: <p>I have the layout code below in xaml</p>
  
  <pre><code>&lt;Grid&gt;
     &lt;StackPanel x:Name="TestStackPanel" Grid.Row="2" Orientation="Horizontal"&gt;
        &lt;ScrollViewer x:Name="TestScrollViewer" Height="300" VerticalScrollBarVisibility="Auto"&gt;
           &lt;GridView x:Name="TestGridView"
              Width="940"
              Background="{StaticResource ApplicationPageBackgroundThemeBrush}"
              ItemTemplate="{StaticResource TestTemplate}"
              ItemsPanel="{StaticResource TestItemPanelTemplate}" 
              ItemContainerStyle="{StaticResource TestItemStyle}" 
              SelectionMode="None"                                  
              HorizontalAlignment="Left"/&gt;
         &lt;/ScrollViewer&gt;
         &lt;Button x:Name="TestButton" Content="ClickMe" VerticalAlignment="Bottom" Margin="10,5,0,0" Click="TestButton_Click"/&gt;
   &lt;/StackPanel&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>This displays well in 1366*768 resolution, but if I change the resolution to 2560*1400, it couldn't displays as expected, I know it's certain, but how to adpat the layout to different resolutions? I have tried to add a ViewBox to encapsulate the Grid, it works well in FullScreenLandScape view, but when I change the app to Snap view, the Grid displays in a samll space.</p>
  
  <p>Anyone can help?</p>
