Style.DataTrigger on Border background
提问by Miles
I have the border below. Why would the Foreground of my TextBlock work correctly but the Background of the border always stay the same (as if the IsDeleted property is always false)
我有下面的边框。为什么我的 TextBlock 的前景可以正常工作，但边框的背景始终保持不变（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>

You have explicitely set the background value on the border. This has more priority than the trigger. Remove the Background="#CBE2FF"and take it into the style.
您已经明确设置了边框上的背景值。这比触发器具有更高的优先级。取下Background="#CBE2FF"并将其带入样式中。
<Border.Style>
<Style TargetType="{x:Type Border}">
<Setter Property="Background" Value="#CBE2FF"/>
...
This will help.
这会有所帮助。
