TreeView节点添加和删除事件 [英] TreeView Node Added and Removed Event

问题描述

我正在创建一个继承TreeView的自定义TreeView控件.当从TreeView添加节点或从中删除节点时，我需要执行一些操作，但是看不到事件，甚至我可以重写以实现此目的的受保护TreeView函数.我想念什么吗?看来这将是人们普遍使用的通知.或者，如果不存在，是否有人知道解决方法?例如，当添加或删除节点时，有另一个事件可以触发.感谢任何帮助.

I am creating a custom TreeView control that inherits TreeView.  I need to perform some actions when nodes are added or removed from the TreeView but don't see an event, or even a protected TreeView function that I can override to accomplish this.  Am I missing something?  It seems like this would be a notification that people would commonly use.  Or if it doesn't exist, does anyone know of a workaround??  For example is there another event I can listen to that gets fired when nodes are added or removed.  Any help is appreciated.
