通过按钮在Windows窗体中对Treeview执行下一个和上一个操作 [英] Performing next and previous operation on treeview in windows form via buttons

问题描述

我正在使用树形视图并插入了一些节点...说
Parent1
child1
child2
parent2
child1
child2
child3
parent3
child1

依此类推..现在有两个按钮下一个"和上一个"，我要分别在下一个"按钮单击和上一个"按钮单击上选择选定父级中的下一个和上一个节点.一旦选择了父级的最后一个节点，则下一个按钮将失去其可见性，与上一个按钮相同.否则两个按钮都可见.
请帮助我.也请提供代码..
