    display children of children

    im using the nodefactory to display children of a specified node:

     

            Node node = new umbraco.presentation.nodeFactory.Node(1125);

            Nodes childrenNodes = node.Children;

            RptDisplayResults.DataSource = childrenNodes;

            RptDisplayResults.DataBind();

    this works fine. But i need to display the children of these children as well. Basically every node including grandchildren of the specified node. How can i do this?

    Out of my mind some code with recursion:

    public void MethodWhereIFilledTheList()
    {
      Node parentNode = new umbraco.presentation.nodeFactory.Node(1125);
      List<Node> myList = new List<Node>();
      AddChildNodes(myList, parentNode);
    }

    public void AddChildNodes(List<Node> list, Node parentNode)
    {
      for each (Node child in parentNode.Children)
      {
        list.Add(child);
        AddChildNodes(list, child);
      }
    }

    hth, Thomas

    or how about an xpath expression with the the following method:

        public static List<Node> GetNodesFromXpath(string xPath)
        {
            List<Node> nodes = new List<Node>();

            XPathNavigator xPathNavigator = umbraco.content.Instance.XmlContent.CreateNavigator(); //get all umbraco xml
            XPathNodeIterator xPathNodeIterator = xPathNavigator.Select(xPath); //TODO: check xpath string is valid

            int id;
            Node node;

            while (xPathNodeIterator.MoveNext())
            {
                if (int.TryParse(xPathNodeIterator.Current.Evaluate("string(@id)").ToString(), out id)) //check id is a numberic
                {
                    node = new Node(id);
                    if (node != null) { nodes.Add(node); }
                }
            }

            return nodes;
        }
