Data source for grid not working

[Alex]

HI Telerik Team,

 I am trying to populate grid using datasource. but the grid is not populating

 

asmx

 [WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public string GetTasks1()
        {
            JavaScriptSerializer theSerializer = new JavaScriptSerializer();
               string result = "";
                List<rt_aw_user_task_details> resultList = new List<rt_aw_user_task_details>();

                AW_USER_TASK_DETAILS taskDetails = new AW_USER_TASK_DETAILS();             
                taskDetails.Query.Load();

                resultList = taskDetails.ToRemotableList();            

                var data = resultList.Select(i => new { i.seq_no, i.task_id, i.category }).ToList();
                result =  new JavaScriptSerializer().Serialize(data);
                return result;           
        }​

aspx page

  $(document).ready(function () {​

            var tasksDataSource = new kendo.data.DataSource({
                type: "json",
                serverFiltering: true, serverPaging: true,  serverSorting: true,  pageSize: 10,
                transport: {
                    read: {
                        datatype: "json",
                        type: "POST",
                        url: "Service/MyTasks.asmx/GetTasks"
                    }
                }
            });

            tasksDataSource.read();

            $("#grid").kendoGrid({
                dataSource: tasksDataSource,
                height: 400,
                groupable: true,
                sortable: true,
                pageable: {
                    refresh: true,
                    pageSizes: true,
                    buttonCount: 5
                },
                columns: [{
                    field: "seq_no",
                    title: "CATEGORY"
                }, {
                    field: "task_id",
                    title: "FREQUENCY"
                }, {
                    field: "category",
                    title: "ISANYTIME",
                }]
            }); 

      });

 The grid is not loading.......

Is there anything i am missing??

 

and the service returns the following data

[{ "seq_no": 2, "task_id": 96, "category": "Task" }, { "seq_no": 3, "task_id": 92, "category": "Report To Review" },
                { "seq_no": 4, "task_id": 99, "category": "Meeting" }, { "seq_no": 5, "task_id": 96, "category": "Task" },
                { "seq_no": 6, "task_id": 96, "category": "Task" }, { "seq_no": 7, "task_id": 93, "category": "Report To Send" },
                { "seq_no": 8, "task_id": 99, "category": "Meeting" }, { "seq_no": 9, "task_id": 96, "category": "Task" },
                { "seq_no": 10, "task_id": 96, "category": "Task" }, { "seq_no": 11, "task_id": 99, "category": "Meeting" }]

 

But it is working when I give the data directly

 var tasksDataSource = new kendo.data.DataSource({
                data: [
                { "seq_no": 2, "task_id": 96, "category": "Task" }, { "seq_no": 3, "task_id": 92, "category": "Report To Review" },
                { "seq_no": 4, "task_id": 99, "category": "Meeting" }, { "seq_no": 5, "task_id": 96, "category": "Task" },
                { "seq_no": 6, "task_id": 96, "category": "Task" }, { "seq_no": 7, "task_id": 93, "category": "Report To Send" },
                { "seq_no": 8, "task_id": 99, "category": "Meeting" }, { "seq_no": 9, "task_id": 96, "category": "Task" },
                { "seq_no": 10, "task_id": 96, "category": "Task" }, { "seq_no": 11, "task_id": 99, "category": "Meeting" }]
            });

            tasksDataSource.read();​
