Wpf 如何删除VerticalAlignment=Center上显示的DatagridTextCell周围的边框？

我希望在

数据网格中显示日期值，而文本在行的中心垂直对齐，而不是在顶部。如果在
DataGridCell
样式中更改
VerticalAlignment
属性，则文本将正确对齐，但会显示一个框架。将
BorderThickness
设置为0并不能解决此问题

我如何去掉边框/边框，同时显示行中间的文本？< /P>
DataGrid
Style

<Style x:Key="StandardTabelle" TargetType="{x:Type DataGrid}">
    <Setter Property="Margin" Value="5"/>
    <Setter Property="Background" Value="White"/>
    <Setter Property="AlternatingRowBackground" Value="#ebecec"/>
    <Setter Property="FontSize" Value="12" />
    <Setter Property="RowHeight" Value="24"/>
    <Setter Property="ColumnHeaderStyle" Value="{StaticResource StandardSpaltenKopf}" />
    <Setter Property="CanUserAddRows" Value="False"/>
    <Setter Property="CanUserDeleteRows" Value="False"/>
    <Setter Property="CanUserReorderColumns" Value="False"/>
    <Setter Property="CanUserResizeRows" Value="False"/>
    <Setter Property="CanUserResizeColumns" Value="False"/>
    <Setter Property="IsReadOnly" Value="True" />
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="RowStyle" Value="{StaticResource AusgewählteZeile}"/>
    <Setter Property="VerticalContentAlignment" Value="Center" />
    <Setter Property="VerticalAlignment" Value="Center"/>
</Style>



选定行的样式

<Style x:Key="AusgewählteZeile" TargetType="{x:Type DataGridRow}">
    <Style.Triggers>
        <Trigger Property="IsSelected" Value="True">
            <Setter Property="Background" Value="{StaticResource Rot}"/>
        </Trigger>
    </Style.Triggers>
</Style>



具有顶部对齐的Datecell样式

<Style x:Key="DatumZelle" TargetType="DataGridCell">
    <Setter Property="HorizontalContentAlignment" Value="Right"/>
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="VerticalAlignment" Value="Center"/>
    <Setter Property="HorizontalAlignment" Value="Stretch"/>
    <Setter Property="BorderThickness" Value="0"/>
    <Style.Triggers>
        <Trigger Property="IsSelected" Value="True">
            <Setter Property="Background" Value="Transparent" />                
        </Trigger>
    </Style.Triggers>
</Style>



您可以创建自定义的
控制模板
：

<Style x:Key="DatumZelle" TargetType="DataGridCell">
    <Setter Property="HorizontalAlignment" Value="Stretch"/>
    <Setter Property="BorderThickness" Value="0"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type DataGridCell}">
                <Grid Background="{TemplateBinding Background}">
                    <ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Right" />
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Style.Triggers>
        <Trigger Property="IsSelected" Value="True">
            <Setter Property="Background" Value="Transparent" />
        </Trigger>
    </Style.Triggers>
</Style>
