如何在不展开父节点的情况下访问内部TreeViewItem节点
我有一个绑定到自定义对象集合的 WPF TreeView - 每个对象都有一个 IsExpanded 属性来展开容器 TreeViewItem。我希望能够以编程方式访问每个 TreeViewItem 的控件内容，而无需扩展可视树中的父 TreeViewItem。但是，当我尝试访问所述项目而不扩展其父项时，它们似乎尚未添加到可视化树中。有谁知道解决这个问题的方法吗？
I have a WPF TreeView that is bound to a collection of custom objects - each of which has an IsExpanded property to expand the container TreeViewItem. I want to be able to programmatically access each TreeViewItem's control contents without expanding the parent TreeViewItem in the visual tree. However, when I attempt to access said items without expanding their parent it seems as if they have not been added to the visual tree yet. Does anyone know a work around for this?
