Question

If I want to display an underlined value in a TextBlock, I have to use a Run element. (If there’s a better/easier way, I’d love to hear about it.)

<TextBlock>   <Run TextDecorations='Underline' Text='MyText' /> </TextBlock> 

Ideally, to implement this within a DataTemplate, it would look something like this:

<DataTemplate x:Key='underlineTemplate'>   <TextBlock>     <Run TextDecorations='Underline' Text='{Binding Value}' />   </TextBlock> </DataTemplate> 

This won’t work, however, because the Run’s Text property isn’t a DependencyProperty, so you can’t databind to it. Does anyone know how I can accomplish this?

Answer 1

TextDecoration is an attached property so it can be applied to the TextBlock also. You create some pretty cool effects by templating the TextDecorations property.

See this MSDN article.

<TextBlock TextDecorations='Underline' Text='{Binding Value}' />
