title: XAML grid not auto scaling
body: <p>I'm trying to write a Universal app with a grid with 2 columns and 6 rows, each box containing a textblock. I want the grid to auto scale with the window size, and later on I will get the text scaling with the window as well.</p>
  
  <pre><code>&lt;Grid HorizontalAlignment="Left" Height="1070" Margin="10,10,0,0" VerticalAlignment="Top" Width="1900"&gt;
          &lt;Grid.ColumnDefinitions&gt;
              &lt;ColumnDefinition/&gt;
              &lt;ColumnDefinition/&gt;
          &lt;/Grid.ColumnDefinitions&gt;
          &lt;Grid.RowDefinitions&gt;
              &lt;RowDefinition Height="*"/&gt;
              &lt;RowDefinition Height="*"/&gt;
              &lt;RowDefinition Height="*"/&gt;
              &lt;RowDefinition Height="*"/&gt;
              &lt;RowDefinition Height="*"/&gt;
              &lt;RowDefinition Height="*"/&gt;
          &lt;/Grid.RowDefinitions&gt;
  
          &lt;TextBlock x:Name="DaoTB" HorizontalAlignment="Left" Margin="10,10,0,0" TextWrapping="Wrap" Text="TEST" VerticalAlignment="Top" Height="154" Width="736" FontSize="100" TextAlignment="Center" SelectionChanged="textBlock_SelectionChanged" Grid.Column="1" Grid.Row="0"/&gt;
          &lt;TextBlock x:Name="EthTB" HorizontalAlignment="Left" Margin="10,10,0,0" TextWrapping="Wrap" Text="TEST" VerticalAlignment="Top" Height="154" Width="736" FontSize="100" TextAlignment="Center" SelectionChanged="textBlock_SelectionChanged" Grid.Column="1" Grid.Row="1"/&gt;
          &lt;TextBlock x:Name="LtcTB" HorizontalAlignment="Left" Margin="10,10,0,0" TextWrapping="Wrap" Text="TEST" VerticalAlignment="Top" Height="154" Width="736" FontSize="100" TextAlignment="Center" SelectionChanged="textBlock_SelectionChanged" Grid.Column="1" Grid.Row="2"/&gt;
          &lt;TextBlock x:Name="DgeTB" HorizontalAlignment="Left" Margin="10,10,0,0" TextWrapping="Wrap" Text="TEST" VerticalAlignment="Top" Height="154" Width="736" FontSize="100" TextAlignment="Center" SelectionChanged="textBlock_SelectionChanged" Grid.Column="1" Grid.Row="3"/&gt;
          &lt;TextBlock x:Name="LumTB" HorizontalAlignment="Left" Margin="10,10,0,0" TextWrapping="Wrap" Text="TEST" VerticalAlignment="Top" Height="154" Width="736" FontSize="100" TextAlignment="Center" SelectionChanged="textBlock_SelectionChanged" Grid.Column="1" Grid.Row="4"/&gt;
          &lt;TextBlock x:Name="RipTB" HorizontalAlignment="Left" Margin="10,10,0,0" TextWrapping="Wrap" Text="TEST" VerticalAlignment="Top" Height="154" Width="736" FontSize="100" TextAlignment="Center" SelectionChanged="textBlock_SelectionChanged" Grid.Column="1" Grid.Row="5"/&gt;
      &lt;/Grid&gt;
  </code></pre>
  
  <p>This doesn't auto scale with the window - the text goes off the screen, and when I resize the window, the text just stays in place and goes off the screen. How can I make the grid resize with the size of the window?</p>
