c# - 如何在 WPF 中设置 DataGrid header 的样式

Question

我有一个像这样的 DataGrid:

<DataGrid AutoGenerateColumns="False"  
          Height="221" 
          HorizontalAlignment="Center" 
          VerticalContentAlignment="Center" 
          HorizontalContentAlignment="Center" 
          Margin="6,269,0,0" 
          Name="dataGrid1" 
          VerticalAlignment="Center" 
          Width="875" 
          SelectionChanged="dataGrid1_SelectionChanged">
    <DataGrid.Columns>
        <DataGridTextColumn x:Name="Id" 
                            Header="ID"
                            Binding="{Binding Path=Key}" 
                            HeaderStyle="" />
        <DataGridTemplateColumn Header="Image" 
                                Width="SizeToCells" 
                                IsReadOnly="True" 
                                MinWidth="80">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <Image Width="16" 
                           Height="16"
                           Source="{StaticResource MyImageSource}"
                           HorizontalAlignment="Center" 
                           VerticalAlignment="Center"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

如何使 DataGrid Header 居中？并为其应用样式？

谢谢

写完这段代码后:

<DataGrid.ColumnHeaderStyle>
    <Style TargetType="{x:Type DataGridColumnHeader}">
        <Setter Property="FontWeight"  Value="Bold" />
        <Setter Property="HorizontalAlignment" Value="Center" />
        <Setter Property="HorizontalContentAlignment" Value="Center" />
    </Style>
</DataGrid.ColumnHeaderStyle>

为什么？

要避免标题折叠的影响，只需以这种方式更正您的样式:

  <Setter Property="HorizontalAlignment" Value="Stretch" />
  <Setter Property="HorizontalContentAlignment" Value="Center" />
