Javascript error when trying to return data for a schedule

[Cornel Amarandei]

Hi,

I have this error when trying to return data for a schedule: "Uncaught TypeError: Cannot read property 'StartTime' of undefined" in ej.web.all.min.js.

My controller action looks like this:

public JsonResult Batch(EditParams param)

        {
            var data = new List<ScheduleData>();
            data.Add(new ScheduleData() { Subject = "Testing", StartTime = DateTime.Now, EndTime = DateTime.Now.AddDays(3), AllDay = true, Owner = 1 });
            return Json(data.AsEnumerable(), JsonRequestBehavior.AllowGet);

        }

The class ScheduleData looks like this:

public class ScheduleData

    {

        public int Id;

        public string Subject;

        public string Location;

        public System.DateTime StartTime;

        public System.DateTime EndTime;

        public string Description;

        public System.Nullable<int> Owner;

        public System.Nullable<int> Priority;

        public System.Nullable<byte> Recurrence;

        

        public string Categorize;

       

        public System.Nullable<bool> AllDay;        

    }

And the Schedule code is this:

 @(Html.EJ().Schedule("Schedule1")

    .Width("100%")

    .Height("525px")

    .CellWidth("40px")

    .Orientation(Syncfusion.JavaScript.Orientation.Horizontal)

    .ShowCurrentTimeIndicator(false)

    .CurrentDate(DateTime.Now)

    .Views(views)

    //.AllowDragDrop(true)

    //.ShowAllDayRow(true)

    .Resources(res => { res.Field("OwnerId").Title("Owner").Name("Owners").AllowMultiple(true).ResourceSettings(flds => flds.Datasource((IEnumerable<object>)ViewBag.Owners).Text("text").Id("id").Color("color")).Add(); })

    .Group(gr => { gr.Resources(ViewBag.Resources); })

    //.AppointmentSettings(fields => fields.Datasource(ViewBag.datasource)

    .AppointmentSettings(fields => fields.Datasource(ds => ds.URL("/Projects/GetData").CrudURL("/Projects/Batch"))

        .Id("Id")

        .Subject("Subject")

        .StartTime("StartTime")

        .EndTime("EndTime")

        .Description("Description")

        .AllDay("true")

        .Recurrence("Recurrence")

        .RecurrenceRule("RecurrenceRule"))

    )

The error comes after I try to insert a new appoitment, so after the return from the Batch action.

Thank you!

Hi Cornel,   

  

Thank you for contacting Syncfusion Support.   

  

We suspect that appointment was not saved properly in database, which could have caused the issue. We have prepared a CRUD sample with the provided code example, which can be downloaded from:   

http://www.syncfusion.com/downloads/support/directtrac/172648/ze/Sample-255158734   

  

In the above sample, when an appointment is added/edited/deleted, it will be reflected in the database too. Kindly refer to the below code example used in the sample.   

<Code> 

public JsonResult Batch(EditParams param) 

        { 

            if (param.action == "insert" || (param.action == "batch" && param.added != null))          // this block of code will execute while inserting the appointments 

            { 

                 

            } 

            if (param.action == "remove" || param.deleted != null)                                        // this block of code will execute while removing the appointment 

            { 

                

            } 

            if ((param.action == "batch" && param.changed != null) || param.action == "update")   // this block of code will execute while updating the appointment 

            { 

                

            } 

            IEnumerable data = new DataClasses1DataContext().ScheduleDatas.Take(500); // nw.Appointment.Take(5); 

            return Json(data, JsonRequestBehavior.AllowGet); 

        } 

</Code>
