推荐答案

构建视图模型.

视图模型为您提供了比没有树视图更大的灵活性.帮自己一个忙，不要走视觉树，如果一个父节点不可见，它可能被虚拟化了，你的水平(或深度)图将是错误的.构建一个视图模型来包装您的数据并知道它处于什么级别.

A View model gves you greater flexibility with the treeview than you can achieve without it. Do yourself a favour, dont walk the visual tree, If a parent node is not visible, it could be virtualised away and your level (or depth) figure will be wrong. build a view model that wraps your data and knows at what level it is at.
