文本块样式切换！

Question

我有一种样式，当鼠标悬停在文本块上时会在文本块上加下划线...单击它时我需要将其字体粗细更改为粗体（选定）.. 有什么想法吗？

dnr3 所说的代码示例，一个模板化的 ToggleButton

<Style x:Key="BoldWhenClickedTextBlock" TargetType="ToggleButton" BasedOn="{StaticResource {x:Type ToggleButton}}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ToggleButton">
                <TextBlock x:Name="c_toggleButtonTextBlock" Text="{Binding RelativeSource={RelativeSource AncestorType={x:Type ToggleButton}}, Path=Content}"/>
                <ControlTemplate.Triggers>
                    <Trigger Property="ToggleButton.IsMouseOver" Value="True">
                        <Setter TargetName="c_toggleButtonTextBlock" Property="TextDecorations" Value="Underline"/>
                    </Trigger>
                    <Trigger Property="ToggleButton.IsChecked" Value="True">
                        <Setter TargetName="c_toggleButtonTextBlock" Property="FontWeight" Value="Bold" />
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

然后“TextBlock”ToggleButton 可以使用它

<ToggleButton Style="{StaticResource BoldWhenClickedTextBlock}" Content="My Text.."/>
