仅在子节点中选中复选框？ [英] Checkboxes only in Children Nodes?

问题描述

我有许多按类别分组的项目（节点），我想在 TreeView 中显示它们，其中父级是文本，子级是 CheckBoxes ：

I have many items (Nodes) grouped by category and I want to display them in a TreeView where parent are text and children are CheckBoxes :

+-CategoryA(Text)
---.A1(CheckBox)
---.A2(CheckBox)
+-CategoryB(Text)
---.B1
---.B2
---.B3
+-CategoryC(Text)
---.C1(CheckBox)
---.C2(CheckBox)

这是一个代码示例：

TreeNode testNodeA = new TreeNode("A"); 
TreeNode testNodeB = new TreeNode("B");
TreeNode testNodeC = new TreeNode("C");
TreeNode[] array = new TreeNode[] { testNodeA, testNodeB, testNodeC };
TreeNode cat = new TreeNode("Categorie X", array);
myTreeView.Nodes.Add(cat);

我已经找到了类似的问题此处，但是该解决方案并不优雅，因为它使用 p / invoke

I already found a similar question Here, but the solution is not elegant since it uses p/invoke to call a C++ code.

推荐答案

但是您可以通过将绘制模式设置为 OwnerDrawAll 并确定要呈现的内容来实现。

There might be an easier way; but you can do it by setting the draw mode to OwnerDrawAll and deciding what to render.
