  <pre><code>&lt;DataGrid x:Name="DgUnitVerReefer" HorizontalAlignment="Center" SelectionMode="Single"      SelectionUnit="FullRow" Margin="20,94,26,0" IsReadOnly="True" AutoGenerateColumns="False"     Visibility="Visible" VerticalAlignment="Top" Height="334"      HorizontalGridLinesBrush="#FFA4C4EA" FontFamily="Microsoft New Tai Lue" AlternatingRowBackground="#FFA4C4EA" MouseDoubleClick="DgUnitVerReefer_MouseDoubleClick" FontSize="16" Width="387"&gt;
          &lt;DataGrid.Columns&gt;
              &lt;DataGridTextColumn Header="" Binding="{Binding Path= UNIT_NUMBER}" Width="350" /&gt;
          &lt;/DataGrid.Columns&gt;
  &lt;/DataGrid&gt;
  </code></pre>
