How to underline a TextBlock on a MouseEnter

Hello all,

In a WPF form, I have the following TextBlock. When I move my mouse over it, I would like to see the text of the TextBlock underlined. How can I do that? I tried with TextBlock.Triggers, but it didn't work.

Thanks!

• Use a style:

  <TextBlock Text="Hurrah">
    <TextBlock.Style>
      <Style TargetType="TextBlock">
        <Style.Triggers>
          <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="TextDecorations" Value="Underline" />
          </Trigger>
        </Style.Triggers>
      </Style>
    </TextBlock.Style>
  </TextBlock>
  

  (Style shown inline for brevity; extract into a resource if you're planning to reuse it.)
