Checkboxes only in Children Nodes?

.net-3.5, c#, treeview, winforms

Solution

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

There's a good example of almost exactly what you want here: http://social.msdn.microsoft.com/forums/en-US/winformsdatacontrols/thread/947aaded-6372-4253-8799-2b595f4a39b9/

Problem

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