在UWP XAML中去除HyperlinkButton下划线

Question

我需要去掉HyperLinkButton中内容的下划线。TextDecorations在这个XAML元素中不存在。

<HyperlinkButton x:Name="BtnTeste"
                Width="100" Height="50" BorderThickness="1" 
                HorizontalAlignment="Center"
                Foreground="Black" Background="#ffffff"
                NavigateUri="www.google.com"
                Content="Execute" />

这个下划线在HyperlinkButton的样式中不会显示。幸运的是，你可以很容易地覆盖它的ContentTemplate来去掉它。

<HyperlinkButton Content="my link">
    <HyperlinkButton.ContentTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding}" />
        </DataTemplate>
    </HyperlinkButton.ContentTemplate>
</HyperlinkButton>

就像这样：

<HyperlinkButton>
   <TextBlock Text="Blahblah" />
</HyperlinkButton>

要更改按钮的外观，您需要应用不同的模板。默认模板可以在MSDN中找到。要去掉下划线，您需要将模板中“UnderlineTextBlock”的TextDecoration属性从“Underline”更改为“None”。

<Style TargetType="HyperlinkButton">
  <Setter Property="Foreground" Value="#FF73A9D8" />
  <Setter Property="Padding" Value="2,0,2,0"/>
  <Setter Property="Cursor" Value="Hand"/>
  <Setter Property="HorizontalContentAlignment" Value="Left"/>
  <Setter Property="VerticalContentAlignment" Value="Top"/>
  <Setter Property="Background" Value="Transparent" />
  <Setter Property="Template">
      <Setter.Value>
          <ControlTemplate TargetType="HyperlinkButton">
              <Grid Cursor="{TemplateBinding Cursor}" Background="{TemplateBinding Background}">
                  <vsm:VisualStateManager.VisualStateGroups>
                      <vsm:VisualStateGroup x:Name="CommonStates">
                          <vsm:VisualState x:Name="Normal"/>
                          <vsm:VisualState x:Name="MouseOver">
                              <Storyboard>
                                  <ObjectAnimationUsingKeyFrames Storyboard.TargetName="UnderlineTextBlock" Storyboard.TargetProperty="Visibility" Duration="0">
                                      <DiscreteObjectKeyFrame KeyTime="0">
                                          <DiscreteObjectKeyFrame.Value>

                                  <DoubleAnimation Storyboard.TargetName="FocusVisualElement" Storyboard.TargetProperty="Opacity" Duration="0" To="1"/>
                              </Storyboard>
                          </vsm:VisualState>
                          <vsm:VisualState x:Name="Unfocused"/>
                      </vsm:VisualStateGroup>
                  </vsm:VisualStateManager.VisualStateGroups>
                  <TextBlock
                      x:Name="UnderlineTextBlock"
                      Text="{TemplateBinding Content}"
                      HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                      VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                      Margin="{TemplateBinding Padding}"
                      TextDecorations="Underline"
                      Visibility="Collapsed"/>
                  <TextBlock Canvas.ZIndex="1"
                      x:Name="DisabledOverlay"
                      Text="{TemplateBinding Content}"
                      Foreground="#FFAAAAAA"
                      HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                      VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                      Margin="{TemplateBinding Padding}"
                      Visibility="Collapsed"/>
                  <ContentPresenter 
                      x:Name="contentPresenter"
                      Content="{TemplateBinding Content}"
                      ContentTemplate="{TemplateBinding ContentTemplate}"
                      VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                      HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                      Margin="{TemplateBinding Padding}"/>
                  <Rectangle x:Name="FocusVisualElement" Stroke="#FF6DBDD1" StrokeThickness="1" Opacity="0" IsHitTestVisible="false" />
              </Grid>
          </ControlTemplate>
      </Setter.Value>
  </Setter>

您可以将模板声明为页面资源并从按钮引用它来应用模板。

声明新样式：

<Page.Resources>
    <Style x:Key="NoUnderlineHyperlinkButtonStyle" TargetType="HyperlinkButton">
        <!--template from above here-->
    </Style>
</Page.Resources>

引用它：

<HyperlinkButton Style="{StaticResource NoUnderlineHyperlinkButtonStyle}">No Underline!</HyperlinkButton>

通常我会同意这个观点，但是那个人正在使用win10/UWP，而你的例子是一个silverlight模板。win10 style template 有一些不同之处，并且提供下划线的附加对象不存在。我也不确定文档中的默认样式是否正确，因为我只看到了一个ContentPresenter，如果OP只是右键单击->编辑模板，那么我们可以看到真相。 - Chris W.

使用样式：

<HyperlinkButton Content="link" Style="{ThemeResource TextBlockButtonStyle}"/>
