Как добавить scrollbar к отдельной колонке DataGrid в xaml

Есть XAML:

<DataGrid x:Name="DataGrid"
              AutoGenerateColumns="False"
              Background="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"
              CanUserReorderColumns="False"
              CanUserSortColumns="False"
              HeadersVisibility="Column"
              HorizontalGridLinesBrush="{DynamicResource {x:Static SystemColors.ControlLightBrushKey}}"
              IsReadOnly="True"
              ItemsSource="{Binding FlatNodeList}"
              SelectedItem="{Binding SelectedNode,
                                     Mode=TwoWay}"
              SelectionMode="Single"
              VerticalGridLinesBrush="{DynamicResource {x:Static SystemColors.ControlLightBrushKey}}"
              ScrollViewer.CanContentScroll="True"
              EnableRowVirtualization="True"
              EnableColumnVirtualization="True"
              VirtualizingStackPanel.VirtualizationMode="Recycling"
              VirtualizingStackPanel.IsVirtualizing="True">

            </DataGrid.Resources>
        </DataGrid>

Для колонки Data нужно сделать scrollbar горизонтальный - как это сделать?
