边框背景上的Style.DataTrigger

Question

我有下面的边框.为什么我的TextBlock的前景正常工作但边框的背景始终保持不变(就好像IsDeleted属性始终为false)

<Border DockPanel.Dock="Top" BorderBrush="Black" Background="#CBE2FF" BorderThickness="2" CornerRadius="5" Padding="0" Margin="5">
    <Border.Style>
        <Style TargetType="{x:Type Border}">
            <Style.Triggers>
                <DataTrigger Binding="{Binding IsDeleted}" Value="True">
                    <Setter Property="Background" Value="#A00000"/>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </Border.Style>
    <TextBlock Margin="5" FontWeight="Bold" FontSize="14" Text="Queue Details">
        <TextBlock.Style>
            <Style TargetType="{x:Type TextBlock}">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding IsDeleted}" Value="True">
                        <Setter Property="Foreground" Value="White"/>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </TextBlock.Style>
    </TextBlock>
</Border>

Answer 1

您已明确设置边框上的背景值.这比触发器更优先.删除Background="#CBE2FF"并将其带入样式.

<Border.Style>
   <Style TargetType="{x:Type Border}">
      <Setter Property="Background" Value="#CBE2FF"/>
      ...

这会有所帮助.
