Grid Paging getting 'Object doesnt support property of method 'slice'

[Doug]

I am trying to establish paging using a Kendo Grid.  However when I try I get the ​'Object doesnt support property of method 'slice'' error. 

Here is my code.

JS file

$(function () {
    dataSource.bind("error", dataSource_error);

$("#CollegeProgramsGrid").kendoGrid({
    dataSource: dataSource,
    pageable: true,
    bob: true,
    columns: [
            {title: "CIP Code", field: "CipCode",width: "110px",attributes: { "class": "table-cell-auto text-center" } },
            {title: "Program Name",field: "ProgramName",width: "110px",attributes: { "class": "table-cell-auto text-center" },groupable: false },
            {title: "Degree Type",field: "DegreeType", width: "110px",attributes: { "class": "table-cell-auto text-center" },groupable: false }
        ]
    });

});

function dataSource_error(e) {
    alert(e.status); // displays "error"
}
var dataSource = new kendo.data.DataSource({

    transport: {
        read: {
            url: window.location.origin + "/Program/ProgramListing/2",
           dataType: "json"
        },
        schema: {
            data: "data",
            total: "count",
            model: {
                id: "ProgramID",
                fields: {
                    CipCode: { type: "string" },
                    ProgramName: { type: "string" },
                    Credits: { type: "number" },
                    Tuition: { type: "number" },
                    DegreeType: { type: "string" },
                    HighWage: { type: "boolean" },
                    HighDemand: { type: "boolean" },
                    HighSkill: { type: "boolean" },
                    ProgramID: { type: "number" }
                }
            }
        },

    },
    pageSize: 25,
    serverPaging: true
});

 

Here is my Response Object

public class Response
   {
       public Array data { get; set; }
       public int count { get; set; }

       public Response(Array data, int count)
       {
           this.data = data;
           this.count = count;
       }
   }

This is the controller code

public Response GetProgramsListByCollegeId(int collegeId, int take, int skip)
        {
          var dbContext = new VirtualCounselorEntities();


                var programs = (from p in dbContext.Programs
                            where p.CollegeID == collegeId
                            select new vmProgramListItem {
                                ProgramId = p.ProgramId,
                                CipCode = p.CipCode,
                                CollegeID = p.CollegeID,
                                ProgramName = p.ProgramName,
                                DegreeType = p.DegreeLevel.Name,
                                Tuition = p.Tuition,
                                HighDemand = p.HighDemand,
                                HighSkill = p.HighSkill,
                                HighWage = p.HighWage
                            })
                            .OrderBy(r => r.CipCode)
                            .Skip(skip).Take(take).ToArray() ;

                int count = dbContext.Programs
                            .Where(r => r.CollegeID == collegeId)
                            .Count();


                return new Response(programs, count);


        }

Viewing the request response, I am getting good JSON back. 

{"data":[{"ProgramId":9,"CipCode":"10.0202","ProgramName":"MEDIA TECHNOLOGY-RADIO (1251)","CollegeID":2,"Credits":0,"Tuition":1400,"DegreeType":"Two Year Certification","HighWage":"N","HighDemand":"N","HighSkill":"N"},...

{"ProgramId":30,"CipCode":"15.0699","ProgramName":"GENERAL TECHNOLOGY (0213)","CollegeID":2,"Credits":0,"Tuition":3300,"DegreeType":"Four Year Certification","HighWage":"N","HighDemand":"N","HighSkill":"N"}],"count":176}

 

Everything looks right and appears to match https://github.com/telerik/kendo-examples-asp-net-mvc/blob/master/grid-crud/Views/Home/Index.cshtml

 

Please provide any assistance you can.

Figured it out.  My Schema was nested in my transport. 

Works now.
