三个状态树视图窗体 [英] Three State Treeview Windows Forms

问题描述

标准TreeView的一个缺点是，您无法显示部分选择，表示选择了某些子项。复杂树中的部分选择允许用户容易地确定选择的位置，即使树没有完全展开。类似的想法在manu备份程序中使用，以允许用户选择要备份的文件。

有人知道一种在树视图中进行检查的方法复选框灰色？我想灰色父节点的检查，当它的一些（但不是所有）其子节点被检查。 Kinda就像您在软件安装过程中选择要安装的选项时看到的内容。

我看过几个帖子，但是较旧（2000年，2007年） p>

我现在，在2010年，可能更好的答案是必需的。我使用VS 2008。 Net 3.5，Windows窗体

解决方案

有一个关于代码项目的好文章。 三态树视图控件

One of the frustrations with the standard TreeView is that you can't show a partial selection to indicate that some of the children are selected. A partial selection in a complex tree allows the user to easily determine where the selections are, even if the tree is not completely expanded. A similar idea is used in manu backup programs to allow the user to select the files to be backed up.

Does anyone know of a way to make the checks in a treeview checkbox gray? I want to gray the check of a parent node when some (but not all) of its child nodes are checked. Kinda like what you see when you are selecting options to install during a software installation.

I have seen several post, but is older (2000, 2007 year).

I now, in 2010, the better answer possible is required. I use VS 2008 . Net 3.5 , Windows Forms
