C# 如何设置DataGridHeaderColumn.TextBlock的样式

我的WPF项目中有DataGrid控件，它具有标题列的默认模板样式。默认情况下，标题列包含文本块

我想要的是在不更改标题模板的情况下更改TextBlock的TextWrapping属性

我试着用下面的标题设置标题样式，但没有成功

<Style x:Key="DataGridHeaderStyle" TargetType="DataGridColumnHeader">
    <Setter Property="TextBlock.TextWrapping" Value="WrapWithOverflow" />

    <Style.Resources>
        <Style TargetType="{x:Type TextBlock}">
            <Setter Property="TextWrapping" Value="WrapWithOverflow" />
        </Style>
    </Style.Resources>
</Style>

为什么不使用Blend？实际上，标题的样式如下所示：

<Style x:Key="DataGridColumnHeaderStyle1" TargetType="{x:Type DataGridColumnHeader}">
            <Setter Property="VerticalContentAlignment" Value="Center"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type DataGridColumnHeader}">
                        <Grid>
                            <Themes:DataGridHeaderBorder BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" IsClickable="{TemplateBinding CanUserSort}" IsPressed="{TemplateBinding IsPressed}" IsHovered="{TemplateBinding IsMouseOver}" Padding="{TemplateBinding Padding}" SortDirection="{TemplateBinding SortDirection}" SeparatorBrush="{TemplateBinding SeparatorBrush}" SeparatorVisibility="{TemplateBinding SeparatorVisibility}">
                                <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                            </Themes:DataGridHeaderBorder>
                            <Thumb x:Name="PART_LeftHeaderGripper" HorizontalAlignment="Left" Style="{StaticResource ColumnHeaderGripperStyle}"/>
                            <Thumb x:Name="PART_RightHeaderGripper" HorizontalAlignment="Right" Style="{StaticResource ColumnHeaderGripperStyle}"/>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

ContentPresenter没有文本块作为内容。但您可以编辑它的contenttemplate

<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 x:Key="DataGridColumnHeaderStyle" TargetType="{x:Type DataGridColumnHeader}">
            <Setter Property="VerticalContentAlignment" Value="Center"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type DataGridColumnHeader}">
                        <Grid>
                            <Themes:DataGridHeaderBorder BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" IsClickable="{TemplateBinding CanUserSort}" IsPressed="{TemplateBinding IsPressed}" IsHovered="{TemplateBinding IsMouseOver}" Padding="{TemplateBinding Padding}" SortDirection="{TemplateBinding SortDirection}" SeparatorBrush="{TemplateBinding SeparatorBrush}" SeparatorVisibility="{TemplateBinding SeparatorVisibility}">
                                <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
                                 <ContentPresenter.ContentTemplate>
                                    <DataTemplate>
                                        <TextBlock Text="{Binding}" TextWrapping="WrapWithOverflow"/>
                                        </DataTemplate>
                                    </ContentPresenter.ContentTemplate>
                                </ContentPresenter>
                            </Themes:DataGridHeaderBorder>
                            <Thumb x:Name="PART_LeftHeaderGripper" HorizontalAlignment="Left" Style="{StaticResource ColumnHeaderGripperStyle}"/>
                            <Thumb x:Name="PART_RightHeaderGripper" HorizontalAlignment="Right" Style="{StaticResource ColumnHeaderGripperStyle}"/>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

顺便说一句，使用blend会让它变得更简单。

我使用的是VS 2013 Express，所以我没有blend:（.我希望我有它，但很遗憾一个简单的调整会如此复杂。
