Я создаю шаблон DataGrid со скругленными углами, но столкнулся с этой проблемой: enter image description here

Нижние углы выходят за границы границКак это решить?Я читал эту статью: http://diptimayapatra.wordpress.com/2010/06/28/rounded-corner-datagrid-in-wpf/

Мне нужно сделать то же самое, но в шаблоне.Вот мой код шаблона DataGrid: 

<Style TargetType="{x:Type DataGrid}">
    <Setter Property="Background" Value="{StaticResource ControlContentBrush}"/>
    <Setter Property="RowDetailsVisibilityMode" Value="VisibleWhenSelected"/>
    <Setter Property="ScrollViewer.CanContentScroll" Value="true"/>
    <Setter Property="ScrollViewer.PanningMode" Value="Both"/>
    <Setter Property="Stylus.IsFlicksEnabled" Value="False"/>
    <Setter Property="Margin" Value="5"/>
    <Setter Property="AlternatingRowBackground" Value="#282828"/>
    <Setter Property="HorizontalGridLinesBrush" Value="{StaticResource NormalBorderBrush}"/>
    <Setter Property="VerticalGridLinesBrush" Value="{StaticResource NormalBorderBrush}"/>
    <Setter Property="Template">
        <Setter.Value>

Попробуйте установить ClipToBounds = "True" на границе.

edit: Ах, я думаю, я вижу вашу проблему. Добавьте этот код в просмотрщик: 

<ScrollViewer.OpacityMask>
    <VisualBrush Visual="{Binding ElementName=border}"/>
</ScrollViewer.OpacityMask>

И поместите границу и средство просмотра прокрутки в сетку. 

<grid>
   <border/>
   <scrollviewer/>
</grid>

edit2: Вот код, который работал для меня. 

    <Style TargetType="{x:Type DataGrid}">
