有没有办法在DataGrid中的标题下面绘制分隔线?我已将GridLinesVisibility设置为None,因为除了标题下方的网格线之外我不想要任何网格线。我正在努力寻找一种方法来做到这一点,任何帮助将不胜感激。
这就是我想要实现的目标。

您可以修改DataGridColumnHeader
' ControlTemplate
。
我使用了原始的DataGrid
模板并替换了默认边框,并使用高度为1的Rectangle
填充。
<DataGrid>
<DataGrid.ColumnHeaderStyle>
<Style TargetType="DataGridColumnHeader">
<Style.Resources>
<!-- This style is required for the column resize thumbs -->
<Style x:Key="ColumnHeaderGripperStyle" TargetType="{x:Type Thumb}">
<Setter Property="Width" Value="8" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="Cursor" Value="SizeWE" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Thumb}">
<Border Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Style.Resources>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridColumnHeader}">
<Grid Background="White">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="1"/>
</Grid.RowDefinitions>
<ContentPresenter Grid.Row="0" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
<Thumb Grid.Row="0" x:Name="PART_LeftHeaderGripper" HorizontalAlignment="Left" Style="{StaticResource ColumnHeaderGripperStyle}" />
<Thumb Grid.Row="0" x:Name="PART_RightHeaderGripper" HorizontalAlignment="Right" Style="{StaticResource ColumnHeaderGripperStyle}" />
<Rectangle Grid.Row="1" Height="1" HorizontalAlignment="Stretch" Stroke="Black"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</DataGrid.ColumnHeaderStyle>
</DataGrid>
