WPF TextBlock Style Underline on Mouse Hover
提问by Mike de Klerk
Simple question. Can the following WPF C# code cut down some weight? I mean, WTF, uh... I mean WPF, come one. Have you every seen CSS? I only want to underline the Text when I hover with the mouse just like a link. Do I really have to add 9 lines for that?

<TextBlock x:Name="Cassette_tblPrintLabel" Text="Print Label" Canvas.Left="154" Canvas.Top="215" Foreground="#FF3355FF" Cursor="Hand" MouseDown="Cassette_lblPrintLabel_MouseDown">
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="TextBlock.TextDecoration" Value="Underline" />
</Trigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
Thanks in advance!
提前致谢！

Add the style as resource; then at least you can re-use it. I think that's the best you can do.
将样式添加为资源；那么至少你可以重新使用它。我认为这是你能做的最好的事情。
<Application.Resources>
<Style TargetType="TextBlock" x:Key="HoverUnderlineStyle">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="TextBlock.TextDecorations" Value="Underline" />
</Trigger>
</Style.Triggers>
</Style>
</Application.Resources>
<TextBlock Style="{StaticResource HoverUnderlineStyle}" />
