WRONG ARGUMENTS IN LOAD ON DEMAND FUNCTION

[GiorgioValentini]

I have a problem with loading on demand: when GetData is called the string arguments are set to null and the date is set to the earlier date possible. Which arguments should I use? Is there something wrong in my html code?

 public JsonResult GetData(string CurrentView, DateTime CurrentDate, string CurrentAction)

        {

            DateTime a = GetFirstDayOfWeek(CurrentDate);

            DateTime b = GetLastDayOfWeek(CurrentDate);

            var data = from appoint in _context.Appointments

                       where displayWho.Contains(appoint.OwnerId) &&

                             appoint.StartTime > a && appoint.EndTime < b

                       select appoint;

            var x = data.ToList();

            return Json(x);

        }

<ej-schedule id="Schedule1" width="100%" height="525px" current-date="DateTime.Now" read-only="false" enable-load-on-demand="true">

    <e-resources>

        <e-resource field="OwnerId" title="Owner" name="Owners" allow-multiple="true">

            <e-resource-settings datasource="@ViewBag.Owners" text="text" id="id" color="Color">

            </e-resource-settings>

        </e-resource>

    </e-resources>

    <e-appointment-settings apply-time-offset="false" id='"Id"' subject='"Subject"' start-time='"StartTime"' end-time='"EndTime"' description='"Description"' all-day='"AllDay"' recurrence='"Recurrence"' recurrence-rule='"RecurrenceRule"'>

        <e-datamanager url="/Home/GetData"  crud-url="Home/Batch" adaptor="UrlAdaptor"></e-datamanager>

    </e-appointment-settings>

</ej-schedule>

Hi Giorgio, 

Thank you for contacting Syncfusion Support. 

With the ASP.NET Core projects, the default arguments such as current view, current action and current date can be accessed at the server-end by adding the [FromBody] attribute initially as highlighted below. In your shared code, arguments are passed directly which could be suspected to be the cause of the reported problem. We have prepared a working sample for your reference which can be downloaded from the following location. 

http://www.syncfusion.com/downloads/support/forum/136812/ze/sample1524891896  

public BatchDataResult GetData([FromBody] MyPostModel post) 

        { 

 

            var data = FilterAppointment(post.CurrentDate, post.CurrentAction, post.CurrentView); 

            BatchDataResult result = new BatchDataResult(); 

            result.result = data; 

            result.count = _context.DefaultSchedule.ToList().Count > 0 ? _context.DefaultSchedule.ToList().Max(p => p.Id) : 1; 

            return result; 

        } 

        public class MyPostModel 

        { 

            public DateTime CurrentDate { get; set; } 

            public string CurrentView { get; set; } 

            public string CurrentAction { get; set; } 

        } 

        public class BatchDataResult 

        { 

            public Object result { get; set; } 

            public int count { get; set; } 

        } 

Kindly try out the above sample and let us know if it works on your end and also if you need any further assistance on this. 

Regards, 

Nevitha.
