WPF绑定语法问题 [英] WPF Binding Syntax Question

问题描述

我已经看到了这个语法显示出来，并尝试谷歌它的定义无济于事;什么时候DP势必这种方式，它意味着什么？

I've seen this syntax show up, and have tried to google for it's definition to no avail; what does it mean when a dp is bound this way?

<Grid>
    <ContentControl Content="{Binding}"/>
</Grid>

我是，你必须绑定到DataContext的，或其他元素某些属性的假设下，但是这似乎结合不了了之。

I was under the assumption that you have to bind to some property on the DataContext, or another element, but this appears to bind to nothing.

推荐答案

我相信它意味着你绑定到任何根的结合上下文。所以，如果你在一个DataTemplate是一些列表控件的一部分使用此语法，你会结合无论父控件（列表对照）结合的根目录下。

I believe it means you are binding to the root of whatever the binding context is. So if you use this syntax in a datatemplate that is part of some sort of list control, you would be binding to the root level of whatever the parent control (the list control) was binding to.
