Windows Forms/TreeView: How do I put CheckBoxes only on the leaves?

Question

Selecting CheckBoxes=true on the treeview puts checkboxes on every node. I only want them on the leaves? How?

I think you need to implement an ownerdraw event handler for the nodes like this:

treeView.DrawMode = System.Windows.Forms.TreeViewDrawMode.OwnerDrawAll;
treeView.DrawNode += new System.Windows.Forms.DrawTreeNodeEventHandler(this.treeView_DrawNode);

private void treeView_DrawNode(object sender, DrawTreeNodeEventArgs e)
{
    if(NodeWithCheckBox(e.Node))
    {
       // draw entry with checkbox
       e.DrawDefault = false;
    }
    else
    {
       e.DrawDefault = true;
    }
}
