I am creating a MVC 5 App in asp.net. I want to embed link in each node to direct to details page of the node. I am using jstree to populate the nodes.

Below is the code for Treenode class

C#

public class TreeViewNode
    {
        public string id { get; set; }
        public string parent { get; set; }
        public string text { get; set; }
    }

Code in my Controller

C#

public class HomeController : Controller
    {
        MetadataEntities db = new MetadataEntities();
        public ActionResult Index()
        {
            List<TreeViewNode> nodes = new List<TreeViewNode>();
            //Loop and add the Parent Nodes.
            foreach (Category type in db.Categories)
            {
                nodes.Add(new TreeViewNode { id = type.CATEGORY_INT_ID.ToString(), parent = "#", text = type.DISPLAY });
            }

            //Loop and add the Child Nodes.
            foreach (Term subType in db.Terms)
            {
                nodes.Add(new TreeViewNode { id = subType.TERM_INT_ID.ToString() + "-" + subType.TERM_INT_ID.ToString(), parent = subType.CATEGORY_INT_ID.ToString(), text = subType.BUSINESS_TERM });
            }

            //Serialize to JSON string.
            ViewBag.Json = (new JavaScriptSerializer()).Serialize(nodes);
            return View();
        }

        [HttpPost]
        public ActionResult Index(string selectedItems)
        {
            List<TreeViewNode> items = (new JavaScriptSerializer()).Deserialize<List<TreeViewNode>>(selectedItems);
            return RedirectToAction("Index");
        }

Index View Code

C#

@model WebApplication4.Models.TreeViewNode
@using WebApplication4.Models

    Layout = null;
}

                "types": {

                    },

                    } 
                },
                plugins: ["search", "themes", "types"]
            })
           
            });
        var to = false;
        $('#plugins4_q').keyup(function () {
            if (to) { clearTimeout(to); }
            to = setTimeout(function () {
                var v = $('#plugins4_q').val();
                $('#jstree').jstree(true).search(v);
            }, 250);
        });

 
    </script>
</body>
</html>

When someone clicks on any node it should direct them to Details page of the item using id as the reference and details view.cshtml page generated by the controller. It would be great if anyone can help me out.

I have been trying to figure for past two weeks
