以编程方式搜索和选择 TreeView 项目？
在我的 3d 应用程序中，我有一个 TreeView，它与 3d 场景中的对象的 ObservableCollection 进行数据绑定。 理论上，用户可以单击 3D 视图中的对象，这应该更新 TreeView 以选择相应的项目。 但我不知道具体怎么做。 我所拥有的只是用户选择的 3D 对象。
我该怎么做呢？
In my 3d application, I have a TreeView that is databound to an ObservableCollection of objects in my 3d scene. In theory a user can click on an object in the 3d view, which should update the TreeView to select the corresponding item. But I don't exactly know how. All I have is the 3d object the user picked.
How do I go about doing this?

他有有效的示例源代码，这可以解决各种问题。
Found the solution right here.

And he's got sample source code that works, which kicks all kinds of ass.
我假设树视图和场景项将共享（并由其标识）一个公共 ID 值。 然后，在您的 3D 场景或 Treeview 中，实现并订阅 OnSelectionChanged，您的 TreeView 可能已经有了。 然后，当其中一个更新/更改时，应立即通知另一个，并相应地更新自身。 当然，即使在更新时也要确保吃掉更改，否则您将创建令人讨厌的 OnChange 事件循环。
...或者，我误解了你的问题吗？
I would assume both the treeview and scene item would share ( and be identified by ) a common ID value. Then, in either your 3D scene or Treeview, implement and subscribe to an OnSelectionChanged, which your TreeView probably already has. Then, when one is updated/changed, the other should be notified instantly, and update itself accordingly. Be sure of course to eat the change even on the update or you will create a nasty loop of OnChange events.
... or, did I misunderstand your question?
