我现在想在<>all<>/strong>上工作。 案件:
var visualWindowContent = (UIElement)window.Content;
这种办法将在窗口时发挥作用。 内容是统一教育。 但是,在什么时候,它是一个非视听物品,而当时有一个数据模板? 上述法典将造成一种不好的例外情况。 因此,如何使窗口的图像内容在该案中?
http://www.un.org。 我首先说,视觉疗法。 GetChild (window, 0) 返回无效,但事实上是非核。 我这里的目的是通过视像WindowContent传给Adorner Layer,使核心层扎根。 GetAdorner Layer。 由此可见的是,在通过窗户后,直观儿童,即AdornerDector的后代, no子在直观树中 enough得很深。
采用FindVisual The Child methods in the page associated by @ReedCopsey, this see to work:
var contentPresenter = FindVisualChild<ContentPresenter>( window );
var visualWindowContent = (UIElement)VisualTreeHelper.GetChild( contentPresenter, 0 );
如果你想要内容本身,你就只能使用目标:
object visualWindowContent = window.Content;
在所有情况下,都这样做,因为其内容是独立实体或实际指定的物体。
如果你试图通过数据模板找到这些要素,见。 Find DataTemplate-Generated elements onMSDN for options. 这项工作是通过找到<条码>Contentpresenter和检查<条码>。
