TriStateCheckBoxes=true with Uncheckable nodes results in odd behaviour..

[Nikolaj]

Hi,
I've experienced odd behavior with the RadTreeView when i got 3 levels of nodes.. first 2 leves are normal checkable nodes and the 3. level is uncheckable nodes for info etc.
When i check any of the nodes on the 2. level, the parent node is checked even though it should be marked as undetermined.. first bug. When i uncheck the node i just checked, the parent node still remain checked.

Markup:

<telerik:RadTreeView ID="RadTreeView1" runat="server" ExpandAnimation-Type="None"
CheckBoxes="true" TriStateCheckBoxes="true">
</telerik:RadTreeView>

Code:

  protected void Page_Load(object sender, EventArgs e)
        {
            RadTreeView1.Nodes.Clear();
            RadTreeNode node = null;

            node = new RadTreeNode("AAA", "aaa");
            RadTreeView1.Nodes.Add(node);
            AddNodes(node);
        }

        private void AddNodes(RadTreeNode parent)
        {
            RadTreeNode node = null;

            node = new RadTreeNode("111", parent.Value + "_111");
            AddInfoNodes(node);
            parent.Nodes.Add(node);

            node = new RadTreeNode("222", parent.Value + "_222");
            AddInfoNodes(node);
            parent.Nodes.Add(node);
        }

        private void AddInfoNodes(RadTreeNode parent)
        {
            RadTreeNode node = new RadTreeNode("foo", parent.Value + "_bar");
            node.Checkable = false; //Without this line everything works like it should....
            parent.Nodes.Add(node);
        }
