如何通过数据绑定设置 WPF 超链接的文本? [英] How can I set the text of a WPF Hyperlink via data binding?

问题描述

在 WPF 中，我想创建一个导航到对象详细信息的超链接，并且我希望超链接的文本是对象的名称.现在，我有这个:

In WPF, I want to create a hyperlink that navigates to the details of an object, and I want the text of the hyperlink to be the name of the object. Right now, I have this:

<TextBlock><Hyperlink Command="local:MyCommands.ViewDetails" CommandParameter="{Binding}">Object Name</Hyperlink></TextBlock>

但我希望将对象名称"绑定到对象的实际名称.我想做这样的事情:

But I want "Object Name" to be bound to the actual name of the object. I would like to do something like this:

<TextBlock><Hyperlink Command="local:MyCommands.ViewDetails" CommandParameter="{Binding}" Text="{Binding Path=Name}"/></TextBlock>

但是，Hyperlink 类没有适合数据绑定的 text 或 content 属性(即依赖属性).

However, the Hyperlink class does not have a text or content property that is suitable for data binding (that is, a dependency property).

有什么想法吗?

推荐答案

看起来很奇怪，但确实有效.我们在我们的应用程序中大约有 20 个不同的地方这样做.Hyperlink 隐式构造一个 <Run/> 如果您将文本放入其内容"中，但在 .NET 3.5 <Run/> 中code> 不会让您绑定到它，因此您必须明确使用 TextBlock.

It looks strange, but it works. We do it in about 20 different places in our app. Hyperlink implicitly constructs a <Run/> if you put text in its "content", but in .NET 3.5 <Run/> won't let you bind to it, so you've got to explicitly use a TextBlock.

<TextBlock>
    <Hyperlink Command="local:MyCommands.ViewDetails" CommandParameter="{Binding}">
        <TextBlock Text="{Binding Path=Name}"/>
    </Hyperlink>
</TextBlock>

更新:请注意，从 .NET 4.0 开始，Run.Text 属性 现在可以绑定:

Update: Note that as of .NET 4.0 the Run.Text property can now be bound:

<Run Text="{Binding Path=Name}" />
