我有一个树形控件，我用两个节点启动树控件，其中两个节点由子节点组成。我在对话框中添加了一个按钮，现在当我单击任何根节点并单击此按钮时，我必须复制现有节点，即我复制现有节点。
我能够复制它并显示重复的数据。正是我的问题出现了，即，我无法看到复制的根节点文本，但我能够看到子节点，唯一的问题是根节点无法显示文本。

这是我如何添加copy.For实例在我的树中第一个节点是XXX，现在我点击添加按钮，树控件获取另一个项目为XXX（2），依此类推..像这样
在我的情景中，当我添加时，我正在接受＆＃34;＆＃34;空的东西作为节点，并能够获得子节点。现在再次点击添加我现在得到XXX（2）并再次添加XXX（3）。
我不知道为什么我在调试时无法获取文本显示文本但未设置。
任何人都可以让我知道我做错了什么。
