TreeView: checkboxes only in child nodes

I need a treeview control:

  1. Root nodes don't have checkboxes, only images.
  2. All child nodes have a checkbox + image.

C#, .net 2.0, winforms (not wpf)

You can disable checkbox. First Set TreeView DrawMode property as OwnerDrawAll. Then Under DrawNode method check child node collection and set checked property as false ie.

private void xmlStructureTree_DrawNode(object sender, DrawTreeNodeEventArgs e)
        {
            if (e.Node.Nodes.Count != 0)
            {
                e.Node.Checked = false;
            }
            e.DrawDefault = true;
        }

The WinForms tree view does not support mixed checkbox/non checkboxes nodes by default

You can enable CheckBoxes globally on the tree view and disable them on specific nodes using this method
