如何创建三态复选框，在.NET中的TreeView控件？ [英] How do I create tri-state checkboxes with a TreeView control in .NET?

问题描述

我在Windows TreeView控件窗体项目已经复选框打开。由于TreeView控件有嵌套的节点，我需要的复选框，以便能够有某种三模式选择。我无法找到一个方法来做到这一点（我只能有复选框全部选中或取消选中）。

I have a treeview control in a Windows Forms project that has checkboxes turned on. Because the treeview control has nested nodes, I need the checkboxes to be able to have some sort of tri-mode selection. I can't find a way to do this (I can only have the checkboxes fully checked or unchecked).

如果您需要关于asp.net我认为你需要使用一个第三方组件一个TreeView三态复选框。来看看一个这个，然后点击三态复选框左侧的：

If you need tri-state checkboxes on a treeview on asp.net i think you need to use a third-party component. Take a look a this one, and click "tri-state checkboxes" on the left side:
