在DataGridTextColumn中为TextBlock创建样式

Question

我想创建一个全局样式,为a 内部或内部的所有控件设置VerticalAlignmentto .CenterTextBlockDataGridDataGridTextColumn

我不想将以下内容复制到每个中,DataGridTextColumn因为它感觉重复.

<DataGridTextColumn Header="Some Property" Binding="{Binding SomeProperty}">
    <DataGridTextColumn.ElementStyle>
        <Style TargetType="TextBlock">
            <Setter Property="VerticalAlignment" Value="Center"></Setter>
        </Style>
    </DataGridTextColumn.ElementStyle>
</DataGridTextColumn>

我试过类似下面的东西,但它不起作用,因为DataGridTextColumn不继承FrameworkElement或FrameworkContentElement.DataGrid本身但我尝试进一步包装会导致错误:

<Style TargetType="DataGridTextColumn">
    <Setter Property="ElementStyle">
        <Setter.Value>
            <Style TargetType="TextBlock">
                <Setter Property="VerticalAlignment" Value="Center"/>
            </Style>
        </Setter.Value>
    </Setter>
</Style>

Answer 1

将样式创建为静态资源

<UserControl.Resources>
    <Style x:Key="verticalCenter" TargetType="{x:Type TextBlock}">
        <Setter Property="VerticalAlignment" Value="Center" />
    </Style>
</UserControl.Resources>

然后,您可以将其分配给DataGridTextColumn的ElementStyle

<DataGridTextColumn ElementStyle="{StaticResource verticalCenter}" />

Answer 2

您可以定义CellStyle如下:

<Style x:Key="DataGridCellStyle" TargetType="DataGridCell">
    <Setter Property="FocusVisualStyle" Value="{x:Null}" />
    <Setter Property="BorderThickness" Value="0"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type DataGridCell}">
                <Grid Background="{TemplateBinding Background}">
                    <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

并将其分配给DataGrid : CellStyle="{StaticResource DataGridCellStyle}". 这样,您的所有单元格都将以内容为中心.

编辑:上面的代码来自我的一个项目,还包含删除DataGrid中的网格线的代码.您可以通过更改Grid为Border模板来取回它们.像这样:

<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="{x:Type DataGridCell}">
            <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
                <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
            </Border>
        </ControlTemplate>
    </Setter.Value>
</Setter>
