Telerik网格显示不存在的列ASP.NET MVC

Question

i am prepairing sample report screen, user will choose report from dropdownBox and fill some special options. after it click search Button (Sorgula) it hits Read action from ReportController.

this Controller Returns List (whatever you whish) as Json

now this is working. But Telerik Grid adding different columns which i have never added to result.

There are no columns on grid defined by me. because columns Must occur according to json result

Now My Grid Create Query

$("#ReportResult").kendoGrid({
        selectable: "multiple cell",
        allowCopy: true,
        height: 550,
        groupable: true,
        pageable: true,
        sortable: true,

        pageable: {
             input: true,
            numeric: false
        },

        dataSource: new kendo.data.GanttDataSource({
            pageSize: 20,
            serverPaging: true,
            serverFiltering: true,
            serverSorting: true,
             transport: {
            read: {
                url: '<%= Url.Action("Read", "Report") %>',
                dataType: "json",
                type: "POST",
                data: {
                    ReportID: 1,
                    OrganizationID: 2,
                    StartDate: "22",
                    EndDate: "11",
                    UserName:"dds",
                },
            },
        },

        }),


    });

Read action

public ActionResult Read([DataSourceRequest] DataSourceRequest request, int ReportID,int OrganizationID,string StartDate,string EndDate,string UserName)
    {

        List<COnsumersReport> lis = new List<COnsumersReport>();
        for (int i = 0; i < 99; i++)
        {
            COnsumersReport cc = new COnsumersReport();
            cc.ID = i;
            cc.name = "semih";
            cc.sirname = "Yıldız";
            cc.Borc =i*20.5;
            lis.Add(cc);
        }


        return Json(lis);
    }

And the result. As you see id,parentId,orderId,Title vs has not defined by me.

    public class COnsumersReport
    {
        public int ID { get; set; }
        public string  name { get; set; }
        public string sirname { get; set; }
        public double Borc { get; set; }
    }

Answer 1

The reason was grid datasource . i have used to kendo.data.GanttDataSource grand datasource adding auto columns.

when i try to use kendo.data.DataSource problem is fixed.

 dataSource: new kendo.data.DataSource({
        pageSize: 100,
        serverPaging: true,
            transport: {
                read:  {
                    url: '<%= Url.Action("Read", "Report") %>',
                    dataType: "json", 
                    type: "GET",
                    data: {
                        ReportID: $('#Rapor').val(),
                        OrganizationID: $('#Organizations').val(),
                        StartDate: $('#datepicker').val(),
                        EndDate: $('#datepickerEndDate').val(),
                        UserName: $('#userName').val(),
                    },                        
                },                    
            },
        error: function (req, textStatus, errorThrown) {
            console.log("Error Verdi" + textStatus + ' ' + errorThrown);
        },
        schema: {
            total: function (response) {
            return ResultCount;
            } 
        }
       }),
