Question

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.)
