WPF datagrid排序方向

Question

如何在DataGrid中查看排序按鈕&每列的方向？

甚至更​​好，我怎麼能看到列標題之間的分隔符？

這裏是我的網代碼：

<Window.Resources> 
    <Style x:Key="HeaderTextStyle" 
     TargetType="{x:Type dg:DataGridColumnHeader}"> 
    <Setter Property="Background" 
      Value="DarkSlateGray" /> 
    <Setter Property="Foreground" 
      Value="White" /> 
    </Style> 
</Window.Resources> 

<dg:DataGrid CanUserAddRows="false" 
      RowHeaderWidth="0" 
      x:Name="movieGrid" 
      Background="DarkSlateGray" 
      ItemsSource="{Binding ElementName=This, Path=GameData}" 
      ColumnWidth="*" 
      Margin="5,35,5,5" 
      AutoGenerateColumns="False" 
      ColumnHeaderStyle="{StaticResource HeaderTextStyle}" 
      BeginningEdit="DataGrid_BeginningEdit" 
      CanUserResizeRows="False" 
      CanUserResizeColumns="False"> 
    <dg:DataGrid.Columns> 
    <dg:DataGridTextColumn IsReadOnly="True" 
          Binding="{Binding Title}" 
          Header="Title" /> 
    <dg:DataGridTextColumn IsReadOnly="True" 
          Width="60" 
          Binding="{Binding Score}" 
          Header="Score" /> 
    <dg:DataGridTextColumn IsReadOnly="True" 
          Width="60" 
          Binding="{Binding Year}" 
          Header="Year" /> 
    <dg:DataGridTextColumn IsReadOnly="True" 
          Binding="{Binding Genre}" 
          Header="Genre" /> 
    <dg:DataGridTemplateColumn Width="195" 
           Header="Link"> 
     <dg:DataGridTemplateColumn.CellTemplate> 
     <DataTemplate> 
      <TextBlock Margin="3,0,0,0"> 
      <Hyperlink Tag="{Binding Link}" 
         Click="Link_Click"> 
       <TextBlock Text="{Binding Link}" /> 
      </Hyperlink> 
      </TextBlock> 
     </DataTemplate> 
     </dg:DataGridTemplateColumn.CellTemplate> 
    </dg:DataGridTemplateColumn> 
    <dg:DataGridCheckBoxColumn Width="50" 
           Binding="{Binding Seen}" 
           Header="Seen" /> 
    </dg:DataGrid.Columns> 
</dg:DataGrid> 

非常感謝！
