想右键删除TreeView里面的某一个子项（已解决）

本帖最后由 qsy666888 于 2020-5-11 16:40 编辑

达到目的：在不用左键的情况下，鼠标指针移动到想要删除TreeView里面的某一个子项时，直接右键就可以删除想要删除的那个子项，大侠们！兄弟伙们！该如何操作呢？求指教。
现在我这里只能先左键点击子项，然后再右键删除，但是不能删除自己指定的子项

句柄用错了，那是ID

a大你好！我想再问一下，如果不用 id 的话（id好像需要左键点击后才能获取id地址），那么我如果移动到某一个父项上，按右键（不使用左键），就能添加一项子项在那父项里面去。
（如果使用左键的话，就能实现，但如果使用右键的话，就获取不了id），感谢a大！
