[英]How to bind a dependency property to a window resource in WPF?
Suppose I have a context menu as a window resource: 假设我有一个上下文菜单作为窗口资源:
<Window.Resources>
<ContextMenu
x:Shared="false"
x:Key="ContextMenu">
<MenuItem Header="{??}" />
</ContextMenu>
</Window.Resources>
And I want to bind MenuItem.Header
to a dependency property called MenuItemHeader
on the window. 我想将
MenuItem.Header
绑定到窗口上名为MenuItemHeader
的依赖项属性。 What should {??}
be and what should the code behind in the window class look like? {??}
应该是什么,并且窗口类中的代码应该是什么样?
You could name the window and reference it 您可以命名窗口并引用它
<Window Name="Window" ...>
<MenuItem Header="{Binding MyDp, Source={x:Reference Window}}"...>
MyDp
being the property. MyDp
是属性。 If you don't know how to define a dependency property read the overview . 如果您不知道如何定义依赖项属性,请阅读概述 。
(I would use Source
and x:Reference
as ElementName
usually does not work in disconnected places like ContextMenus
) (我将使用
Source
和x:Reference
因为ElementName
通常在诸如ContextMenus
断开连接的地方不起作用)
