我的代码

Hello ,

Kendo UI experts Please help me..

I am new to Kendo ui. I want to return id of Selected node in kendo treeview in my code.
but it is returning only same node.

On selecting Node i want to return id of selected Node to my code, and in Code i am returning
child elements of that node.

is there any simple way of doing it??

Thanks in advance..

My Code

<div id="treeview"></div>
                                <script src="~/Scripts/kendo.treeview.min.js"></script>
               						<script>
                                         homogeneous = new kendo.data.HierarchicalDataSource({
										        transport: {
										            read: {
										                url: "@Url.Action("datasourcefortree", "Home")",
													    type: "POST",
													    dataType: "json"
                                                    }
												},
											    schema: {
											        model: {
											            id: "ResourceID",
											            hasChildren: true
											        }
											    }
											});

                                            $("#treeview").kendoTreeView({
                                                dataSource: homogeneous,
                                                dataTextField: "Resource"
                                            });

										</script>

和家用控制器的datasourcefortree方法代码

and code of datasourcefortree method of homecontroller

[HttpPost]

        public JsonResult datasourcefortree(int? NodeID)
        {

            FNHSessionManager<resourcemaster> sessionManager = new FNHSessionManager<resourcemaster>(_connString, FNHSessionManager<resourcemaster>.DatabaseType.MsSql);
            FNHRepository<resourcemaster> repository = new FNHRepository<resourcemaster>(sessionManager);
            int nodevalue = 1;

            if (NodeID == null)
            {
                ResourceMaster tree = repository.RetrieveById(nodevalue);
                List<resourcemaster> node = new List<resourcemaster>
            {
                new ResourceMaster
                {
                    ResourceID = tree.ResourceID,
                    Resource=tree.Resource
                }
            };
                return Json(node, JsonRequestBehavior.AllowGet);
            }
            else
            {
                if (NodeID.HasValue)
                {
                    nodevalue = NodeID.Value;
                    IList<resourcemaster> childtreenode = repository.GetAllRecord(nodevalue);
                    return Json(childtreenode, JsonRequestBehavior.AllowGet);

                }
                return (null);
            }


        }

推荐答案

（ ＃treeview）。kendoTreeView（{
dataSource：homogeneous，
dataTextField： 资源
}）;

< / script >

("#treeview").kendoTreeView({ dataSource: homogeneous, dataTextField: "Resource" }); </script>

和家用控制器的datasourcefortree方法代码

and code of datasourcefortree method of homecontroller

[HttpPost]

        public JsonResult datasourcefortree(int? NodeID)
        {

            FNHSessionManager<resourcemaster> sessionManager = new FNHSessionManager<resourcemaster>(_connString, FNHSessionManager<resourcemaster>.DatabaseType.MsSql);
            FNHRepository<resourcemaster> repository = new FNHRepository<resourcemaster>(sessionManager);
            int nodevalue = 1;

            if (NodeID == null)
            {
                ResourceMaster tree = repository.RetrieveById(nodevalue);
                List<resourcemaster> node = new List<resourcemaster>
