Yup you can :) for an example check out this code https://github.com/TimGeyssens/UIOMatic/blob/master/src/UIOMatic/Trees/UIOMaticTreeController.cs

Key is to check the id (if it's -1 then it's the first level, if it's an other id then it's an upper level)

Hi Tim,

Thanks a lot :)

I am trying to add fetched data from DB under respective nodes however the below code is adding it in all the levels instead of giving the id other then -1 :(

        protected override TreeNodeCollection GetTreeNodes(string id, FormDataCollection queryStrings)
        {
            System.Diagnostics.Debugger.Launch();
            var nodes = new TreeNodeCollection();
            var ctrl = new StatusApiController();//calling API controller

           //check if we're rendering the root node's children
            if (id == Constants.System.Root.ToInvariantString())
            {
                //creating node1 and node2
                var node1 = CreateTreeNode("1", "-1", queryStrings, "Node1", "icon-smiley", true);
                var node2= CreateTreeNode("2", "-1", queryStrings, "Node2", "icon-smiley", true);
                nodes.Add(node1);
                nodes.Add(node2);

              //  return nodes;
            }

            //checking child nodes under Node1
            foreach (var addnode1 in ctrl.GetAll())
            {
                var node = CreateTreeNode(
                   addnode1.Id.ToString(),
                    "1",
                    queryStrings,
                    addnode1.Title.ToString(),
                    "icon-document",
                    false);
                nodes.Add(node);

            }
            //checking child nodes under Node2
            foreach (var addnode2 in ctrl.GetAll2())
            {
                var node = CreateTreeNode(
                    addnode2.Id.ToString(),
                    "2",
                    queryStrings,
                    addnode2.Title.ToString(),
                    "icon-document",
                    false);

                nodes.Add(node);

            }
            return nodes; }

Thanks, Harshit

i tried, It not working .same results. Is there a way ,where we can add directly to parent nodes instead of adding them in treenodecollection object. like

nodes.add(node) replaced by

node1.add(node)

Thanks, harshit

Thanks Tim :) Got a way to do it.

Cheers, harshit

is working on a reply...
