WPF 绑定语法问题

问题描述

我已经看到这种语法出现，并试图用谷歌搜索它的定义，但无济于事；以这种方式绑定 dp 是什么意思?

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>

我假设您必须绑定到 DataContext 上的某些属性或其他元素，但这似乎没有绑定.

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

我相信这意味着您正在绑定到任何绑定上下文的根.因此，如果您在属于某种列表控件的数据模板中使用此语法，您将绑定到父控件(列表控件)绑定到的任何根级别.

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.
