在窗体上具有三态功能的VB.Net树视图 [英] VB.Net treeview with tristate functionality on form

问题描述

大家好，

有人可以告诉我在VB.Net中创建三态树视图该怎么做吗?我需要它根据子节点的检查状态来更改父节点的检查状态(已检查，混合或未检查)，并且还需要在检查父节点时检查/取消选中所有子节点.

我知道在线上有示例，但是我不太擅长编程，它们全都使用另一种语言，或者使我感到困惑.我已经将Treeview控件添加到表单中，并且可以正确地填充它(我以编程方式执行)，但是我不知道如何使用三态功能.

谢谢！

Hi guys,

Can someone please tell me what I have to do to create a tri-state treeview in VB.Net? I need it to change the check state of parent nodes (checked, mixed or unchecked) based on the checkstate of the child nodes, and also to check/uncheck all child nodes when the parent node is checked.

I know there are examples online but I am not very good at programming and they all are either in another language or confuse me. I have added a treeview control to a form, and I can get it to populate correctly (which i do programmatically) but I have no idea how to work the tri-state functionality.

Thank you!
