我正在嘗試將列標題的背景設定為深灰色 (#6A767D)，但它不起作用。相反，標題背景是 AlternatingRowBackground 屬性的顏色。也許背景以某種方式被覆寫了？我不確定您是否需要的不僅僅是資料網格的 xaml 代碼。有什么建議？

uj5u.com熱心網友回復：
兩個問題：
- 您實際上從未指定要使用的樣式。我建議您在 Window 或放置 DataGrid 的任何面板的資源中定義樣式。
<Window.Resources>
<Style x:Key="DatagridColumnHeaderStyle_Basic" TargetType="{x:Type DataGridColumnHeader}">
<Setter Property="Width" Value="Auto"/>
<Setter Property="Background" Value="#6A767D" />
<Setter Property="VerticalContentAlignment" Value="Center" />
<Setter Property="Padding" Value="10" />
<Setter Property="FontWeight" Value="SemiBold" />
<Setter Property="FontFamily" Value="Arial" />
<Setter Property="TextElement.Foreground" Value="White"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridColumnHeader}">
<Grid Name="HedearGrid" Background="{TemplateBinding Background}" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<ContentPresenter Margin="6,3,6,3" VerticalAlignment="Center" Grid.Column="0" />
<Path x:Name="SortArrow" Visibility="Collapsed" Data="M0,0 L1,0 0.5,1 z" Stretch="Fill"
Grid.Column="1" Width="8" Height="6" Fill="Blue" Margin="0,0,8,0"
VerticalAlignment="Center" RenderTransformOrigin="0.5,0.4" />
<Thumb x:Name="PART_RightHeaderGripper" HorizontalAlignment="Right" Cursor="SizeWE"
Grid.Column="1" >
<Thumb.Style>
<Style TargetType="{x:Type Thumb}">
<Setter Property="Width" Value="2" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Thumb}">
<Border Background="Transparent"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Thumb.Style>
</Thumb>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="SortDirection" Value="Ascending">
<Setter TargetName="SortArrow" Property="Visibility" Value="Visible" />
<Setter TargetName="SortArrow" Property="RenderTransform">
<Setter.Value>
<RotateTransform Angle="180" />
</Setter.Value>
</Setter>
</Trigger>
<Trigger Property="SortDirection" Value="Descending">
<Setter TargetName="SortArrow" Property="Visibility" Value="Visible" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
然后，您可以像這樣將它分配給您的 DataGrid：
<DataGrid ColumnHeaderStyle="{StaticResource DatagridColumnHeaderStyle_Basic}"/>
或者，只需 remove x:Key="DatagridColumnHeaderStyle_Basic"，那么您不必指定。
- （在上面的代碼中為你修復）你用 AliceBlue 覆寫你的背景：
<Grid Name="HedearGrid" Background="AliceBlue">
應該：
<Grid Name="HedearGrid" Background="{TemplateBinding Background">
