WPF 2. 具有约束力的协同问题
原标题:WPF Binding Syntax Question

我看到了这一辛迪加,并试图回避其定义,使之无法奏效;它意味着什么时候以这种方式约束 d子?

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

我的假设是,你必须对数据内容上的某些财产或另一要素加以约束,但这似乎毫无约束力。

最佳回答

我认为,这意味着,无论具有约束力的背景是什么,都对你具有约束力。 因此,如果你在属于某种名单控制一部分的数据模板中使用这一辛迪加,那么,无论父母控制(名单控制)对谁有约束力,你都将受到约束。

问题回答

我认为{具有约束力的}指的是数据内容本身。

编辑(声明): 按数据分类 我指的是目前的数据背景。 例如,如果你的窗口数据目录受清单的约束,那么把物品列入清单Box控制窗口至{具有约束力的}就将清单Box与清单本身联系起来,而不是像数字一样属于清单的财产。

{具有约束力的}用于{具有约束力的[案文]}

{具有约束力的}是指您希望与现存数据目录保持一致,这些内容可放在标本上。 如果在目前的目标上没有数据内容,那么它就会走眼镜,找到最亲近的父母,掌握数据。
