推荐答案

只要告诉我1件事，如果我使用
"TreeNodePopulate事件"如何确定祖父是单击还是父亲
treeview的节点级别会告诉您.如果是0级，则单击祖父"节点.如果是第一级节点，则为父亲，第二级则为子节点.

Just tell me 1 thing If i use
"TreeNodePopulate event" How can i defferntiate Grandfather is click or father
Node level of the treeview would tell you that. If it''s 0th level, then Grandfather node clicked. If 1st level node then a father and 2nd level then child.
