Question

我希望在TabItem Header时将FontWeight Bold IsSelected = True更改为ResourceDictionary。< / p>

部分代码

 <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type TabItem}">
                <Grid>
                    <Border Name="Border"
                            Background="White"
                            BorderBrush="White" 
                            BorderThickness="1,1,1,0"
                            Margin="0,0,0,-1" >
                        <ContentPresenter x:Name="ContentSite"
                                          Height="25"
                                          VerticalAlignment="Bottom"
                                          HorizontalAlignment="Center"
                                          ContentSource="Header"
                                          Margin="12,2,12,2"/>
                    </Border>
                </Grid>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsSelected" Value="True">
                        <Setter TargetName="Border" Property="Background" Value="#F2F1F0" />
                        <Setter TargetName="Border" Property="BorderBrush" Value="Gray" />
                        <Setter TargetName="Border" Property="BorderThickness" Value="0.5,0.7,0.5,0" />
                        <Setter Property="Header">
                            <Setter.Value>
                                <TextBlock Text="{Binding Path=Header.Title, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type TabItem}}}"
                                           FontWeight="Bold" />
                            </Setter.Value>
                        </Setter>
                    </Trigger>
                    <Trigger Property="IsSelected" Value="False">
                        <Setter TargetName="Border" Property="Background" Value="White" />
                        <Setter TargetName="Border" Property="BorderBrush" Value="Gray" />
                        <Setter TargetName="Border" Property="BorderThickness" Value="0,0,0,0.5" />
                    </Trigger>

.....etc.....

上述方法不起作用。同时设置HeaderTemplate代替Header它可以工作，但它会破坏我的模板。最后，将TextBlock.FontWeight设置为Property Trigger会更改TextBlock内的所有TabItem。

任何提案？

更新

我接受了@ShineKing的答案，因为它帮助我解决了我的问题。基本上我所做的就是将DataTrigger添加到用作TextBlock的{{1}}到我的＆＃34; custom＆＃34; Header。

您是否可以尝试使用此代码将TextBlock更改为Bold

<TabControl>
   <TabControl.Resources>
      <Style TargetType="TextBlock" x:Key="HeaderTextBlockStyle">
         <Style.Triggers>
            <DataTrigger Binding="{Binding IsSelected,
                          RelativeSource={RelativeSource AncestorType=TabItem}}"
                         Value="True">
                <Setter Property="FontWeight" Value="Bold"/>
             </DataTrigger>
          </Style.Triggers>
       </Style>
    </TabControl.Resources>
    <TabItem>
       <TabItem.Header>
          <TextBlock Text="Header Text"
                     Style="{StaticResource HeaderTextBlockStyle}"/>
       </TabItem.Header>
    </TabItem>
</TabControl>

更改TabItem的标题字体权重
