WPF：将TextBlock文本值绑定到WPF中的所选按钮内容：纯XAML

[英]WPF: Bind TextBlock Text Value to Selected Button Content in WPF: Pure XAML

原文 2014-05-09 08:21:48 8 1 c#/ wpf/ xaml/ data-binding/ mvvm

Not sure if this can be done - I've got a WPF Application with a bunch of XAML screens and what I'd like to be able to do on one of them is bind the Text value of a TextBlock to the Content Value of a selected button. 不知道是否可以这样做-我有一个带有一堆XAML屏幕的WPF应用程序，而我想在其中一个屏幕上执行的操作是将TextBlock的Text值绑定到一个选择的按钮。 I've got say 5 buttons in my XAML and when I click any of them I want the text block to reflect the button content. 我在XAML中说了5个按钮，当我单击其中的任何一个时，我都希望文本块反映按钮的内容。 I know I can do this through Commands ala MVVM but I'd love to do this in pure XAML - no code at all. 我知道我可以通过Commands ala MVVM来做到这一点，但是我很想在纯XAML中做到这一点-完全没有代码。

Can it be done? 能做到吗

Thanks heaps! 谢谢堆！

Add a trigger on your buttons individually or as a template shared by all of them to do a ChangePropertyAction with your TextBlock as the TargetObject to its Text property with the Buttons content and voila, you're done. 在按钮上单独添加触发器或将其添加为所有按钮共享的模板，以将TextBlock作为TargetObject进行ChangePropertyAction，并将其添加到Buttons内容的Text属性中，这样就完成了。
