title: Align Grid column to right
body: <p>I have a Windows Phone / XAML Grid composed by 3 columns. In particular, I want the third column to be aligned to the very right side of the screen.</p>
  
  <pre><code>&lt;Grid Background="Transparent" Margin="0,3"&gt;
          &lt;Grid.ColumnDefinitions&gt;
              &lt;ColumnDefinition Width="Auto"/&gt;
              &lt;ColumnDefinition Width="*"/&gt;
              &lt;ColumnDefinition Width="Auto"/&gt;
          &lt;/Grid.ColumnDefinitions&gt;
  
      &lt;Image Grid.Column="0" x:Name="Marker" Width="60" Height="60" VerticalAlignment="Center" Stretch="Uniform" HorizontalAlignment="Center"/&gt;
      &lt;TextBlock Grid.Column="1" x:Name="Name" TextAlignment="Left" VerticalAlignment="Center" Margin="20,0" /&gt;
      &lt;Image Grid.Column="2" x:Name="Selected" Width="48" Height="48"  VerticalAlignment="Center" Stretch="Uniform" HorizontalAlignment="Center"/&gt;
   &lt;/Grid&gt;
  </code></pre>
