Not sure if anyone found this or not as its been a few years since this thread was active but since this is the first thread I found in searching for this question, I figured I would add it here...

This seems to work quite fine... as I have two controls on my page, a XmlDataSource and an UltraWebTree. In my code behind during the PreRender (or where ever you want to do it, such as Load or another event) I have the following:

 MyXmlDataSource.XPath = "//SomeNodes/*[@enabled!='false']";

MyXmlDataSource.Data = "<SomeNodes><Node1 enabled=\"false\"><Node11><Node111 /></Node11></Node1><Node2 enabled=\"true\"><Node21><Node211 /></Node21><Node22><Node221 /></Node22></Node2></SomeNodes>"

;

MyUltraWebTree.DataSource = MyXmlDataSource;

MyUltraWebTree.DataBind();

This will set the root xml data presented from the XmlDataSource to be all the child nodes of the root Location node that dont have a attribute "enabled" equal to "false".  So as long as the XPath selects the children of the root node, that's what your tree should show.  You dont need the "[@enabled!='false']" parth of the XPath but I just thought it useful to show for easily filtering the tree content.

Hello,

You can always suggest a new feature for any IG product using our Request Feature center located here: 

http://devcenter.infragistics.com/Protected/RequestFeature.aspx 

Our PMs regularly go through these and prepare a list of what to be implemented in the next release. Clone() functionality seems very reasonable (and in fact I can guarantee that it is already implemented in our next next generation treeview control - WebDataTree from the Aikido suite). 

In any case, you can extend node and createyour own clonable node instance using something similar to:

   protected void Page_Load(object sender, EventArgs e)
    {
        UltraWebTree1.Nodes.Add(new ClonableNode("Node Clone"));
    }



    public class ClonableNode : Node
    {
        public ClonableNode(string text)
            : base()
        {
            this.Text = text;
        }

        public Node Clone()
        {
            Node node = new Node();
            node.Text = this.Text;
            node.TargetUrl = this.TargetUrl;
            node.Selected = this.Selected;

            return node;
        }
    }

Would it be possible to request that a Clone() method be added to the Node class?  

I am not sure this is technically possible, since the nature of hierarchical databound controls like UltraWebTree is that they inherit behaviour from their parents - removing / hiding a node will do the same for all it's child nodes.

I guess, you can enumerate all nodes in the original treeview starting from the first sub-root and copy them to another treeview, and use the latter instead. Something along the lines of:

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            CopyNodeCollection(UltraWebTree1.Nodes[0].Nodes, UltraWebTree2.Nodes);
        }
    }

    private void CopyNodeCollection(Nodes sourceNodes, Nodes destNodes)
    {
        foreach (Node node in sourceNodes)
        {
            Node childNode = new Node(node.Text, "", "", "", "");
            destNodes.Add(childNode);

            CopyNodeCollection(node.Nodes, childNode.Nodes);
        }
    }

Hope this helps. 

If we do this way, we will remove all the ChildNodes. how to just hide or remove root node when we display WebTree Control?
