Declaring Text Decorations such as Underline, Strikethrough in a Style
Underlining text can be done either with <Underline>…</Underline> or with the TextDecorations attribute set to Underline. You can include the latter in a style definition: <Style x:Key=”Underlined”> <Setter Property=”TextBlock.TextDecorations” Value=”Underline” /> </Style> <TextBlock Style=”{StaticResource Underlined}”> Foo </TextBlock>
