Question

我在xaml文件中为Tab Control和TabItem创建了样式。

当TabControl第一次加载到窗口时，它的应用样式就像它想要的那样。但是当我选择另一个tabItem时，它没有执行IsSelection属性样式。

选择：Path Stroke =＆＃34; blue＆＃34;和背景Bd =＆＃34;黄色＆＃34;。

请帮我解决这个问题。

提前谢谢。

请尝试以下代码：

<ControlTemplate.Triggers>
    <Trigger Property="IsSelected" Value="False">
        <Setter Property="ToolTip" TargetName="Content" Value="{Binding RelativeSource={RelativeSource AncestorType={x:Type TabItem},Mode=FindAncestor},Path=Header}"/>
        <Setter Property="Fill" TargetName="Bd" Value="{DynamicResource UnSelectedBrush}"/>
        <!--<Setter Property="TextTrimming" TargetName="Content" Value="CharacterEllipsis"/>-->
        <Setter Property="Panel.ZIndex" Value="0"/>
        <Setter Property="Stroke" TargetName="Bd" Value="{DynamicResource WhiteColorBrush}"/>
        <Setter Property="Margin" Value="0,0,0,-1" TargetName="Bd"/>

    </Trigger>

    <Trigger Property="IsMouseOver" Value="True">
        <!--<Setter TargetName="Bd" Property="Opacity" Value="0.6"/>-->
        <Setter Property="Cursor" TargetName="Bd" Value="Hand" />
    </Trigger>

    <Trigger Property="IsSelected" Value="True">
        <Setter Property="Margin" Value="0,0,0,-3" TargetName="Bd"/>
        <Setter Property="Fill" TargetName="Bd" Value="Blue"/>
        <Setter Property="Stroke" TargetName="Bd" Value="Yellow"/>
        <Setter Property="StrokeThickness" TargetName="Bd" Value="2"/>
        <!--<Setter Property="TextBlock.FontWeight" TargetName="Content" Value="DemiBold"/>-->
    </Trigger>
    <!--<MultiTrigger>
        <MultiTrigger.Conditions>
            <Condition Property="IsSelected" Value="false"/>
            <Condition Property="IsMouseOver" Value="true"/>

        <Setter Property="Margin" Value="-1" TargetName="Bd"/>
        <Setter Property="Fill" TargetName="Bd" Value="{DynamicResource UnSelectedItemBrush}"/>
        <Setter Property="Cursor" TargetName="Bd" Value="Hand"/>
        --><!--<Setter Property="TextBlock.FontWeight" TargetName="Content" Value="DemiBold"/>--><!--
    </MultiTrigger>-->
    <Trigger Property="IsEnabled" Value="false">

        <Setter Property="StrokeThickness" TargetName="Bd" Value="2"/>
    </Trigger>
</ControlTemplate.Triggers>
