WPF 超链接中的文本换行

发布于 2024-08-01 20:33:31 字数 418 浏览 5 评论 0原文

在我的 WPF 应用程序中，我有这样的情况：

<StackPanel>
  <TextBlock>
     <Hyperlink>
       <TextBlock TextWrapping="Wrap" Name="HyperlinkText" />
     </Hyperlink>
  </TextBlock>
</StackPanel>

但是，如果我将 HyperlinkText.Text 设置为换行的长文本，则整个文本仅在底部加下划线一次（参见图片）。有没有办法让每行单独加下划线而不需要手动换行？

In my WPF application I have this:

<StackPanel>
  <TextBlock>
     <Hyperlink>
       <TextBlock TextWrapping="Wrap" Name="HyperlinkText" />
     </Hyperlink>
  </TextBlock>
</StackPanel>

But if I set HyperlinkText.Text to a long text that wraps, the whole text is underlined only once at the bottom (see image). Is there a way to have every line underlined separately without manual wrapping?

这是 WPF 中一个非常非常烦人的问题。我什至称其为错误。

正如 @levanovd 在他的回答中提到的，您可以通过使用 Run 作为内部元素来正确换行超链接：

    <StackPanel>
        <TextBlock TextWrapping="Wrap">
            <Hyperlink><Run>This is a really long hyperlink. Yeah, a really really long hyperlink, whaddaya think?</Run></Hyperlink>
        </TextBlock>
    </StackPanel>

这非常有效，直到您想在其中应用文本格式超链接。例如，如果您尝试这样做：

    <StackPanel>
        <TextBlock TextWrapping="Wrap">
            <Hyperlink><Run>This is a really long <Run TextWeight="Bold">hyperlink</Run>. Yeah, a really really long hyperlink, whaddaya think?</Run></Hyperlink>
        </TextBlock>
    </StackPanel>

您会收到编译错误：

对象“Run”已经有一个子对象，无法添加“”。 “奔跑”只能接受一个孩子。

因此，正如 @Scott Whitlock 所指出的，您必须使用 TextBlock 作为内部元素，并使用 Hyperlink 的 TextDecoration 属性和TextBlock 相反：

    <StackPanel>
        <TextBlock>
            <Hyperlink TextDecorations="None"><TextBlock TextWrapping="Wrap" TextDecorations="Underline">This is a really long <Run FontWeight="Bold">hyperlink</Run>. Yeah, a really really long hyperlink, whaddaya think?</TextBlock></Hyperlink>
        </TextBlock>
    </StackPanel>

叹息。我真的很讨厌 WPF 的 Hyperlink 元素。它只是没有像你期望的那样工作。

This is a really, really annoying problem in WPF. I'd go so far as to call it a bug.

As @levanovd mentioned in his answer, you can get a hyperlink to wrap properly by using a Run as the inner element:

    <StackPanel>
        <TextBlock TextWrapping="Wrap">
            <Hyperlink><Run>This is a really long hyperlink. Yeah, a really really long hyperlink, whaddaya think?</Run></Hyperlink>
        </TextBlock>
    </StackPanel>

This works great, until you want to apply text formatting within the hyperlink. If you tried to do this, for example:

    <StackPanel>
        <TextBlock TextWrapping="Wrap">
            <Hyperlink><Run>This is a really long <Run TextWeight="Bold">hyperlink</Run>. Yeah, a really really long hyperlink, whaddaya think?</Run></Hyperlink>
        </TextBlock>
    </StackPanel>

You'd get a compile error:

The object 'Run' already has a child and cannot add ''. 'Run' can accept only one child.

So, as @Scott Whitlock noted, you have to use a TextBlock as the inner element and mess around with the TextDecoration attributes of the Hyperlink and TextBlock instead:

    <StackPanel>
        <TextBlock>
            <Hyperlink TextDecorations="None"><TextBlock TextWrapping="Wrap" TextDecorations="Underline">This is a really long <Run FontWeight="Bold">hyperlink</Run>. Yeah, a really really long hyperlink, whaddaya think?</TextBlock></Hyperlink>
        </TextBlock>
    </StackPanel>

Sigh. I really hate WPF's Hyperlink element. It just doesn't work anything like you'd expect.
