Hi Tirathpal,  
 
Greetings from Syncfusion Support.  
 
We have checked the shared code in which value not mapped in resource which could cause the reported problem. Please check the following sample for your reference.  
 
 
function onPopupOpen(args) { 
        if (args.type === 'Editor') { 
             var ImpData = @Html.Raw(Json.Encode(ViewBag.ImplementLst)); 
            var statusElement = args.element.querySelector('#ImplementId'); 
            if (!statusElement.classList.contains('e-dropdownlist')) { 
                var dropDownListObject = new ej.dropdowns.DropDownList({ 
                    placeholder: 'Choose status', value: args.data.ImplementId, 
                    fields: { text: 'text', value: 'Id' }, 
                    dataSource: [ 
                        { Id: 1, text: 'PROJECT 1' }, 
                        { Id: 2, text: 'PROJECT 2' }, 
                    ] 
                }); 
                dropDownListObject.appendTo(statusElement); 
                statusElement.setAttribute('name', 'ImplementId'); 
            } 
            var startElement = args.element.querySelector('#StartTime'); 
            if (!startElement.classList.contains('e-datetimepicker')) { 
                new ej.calendars.DateTimePicker({ value: new Date(startElement.value) || new Date() }, startElement); 
            } 
            var endElement = args.element.querySelector('#EndTime'); 
            if (!endElement.classList.contains('e-datetimepicker')) { 
                new ej.calendars.DateTimePicker({ value: new Date(endElement.value) || new Date() }, endElement); 
            } 
        } 
    }; 
 
 
 
Please try the sample and revert us back if you still face any issue.

Hi Tirathpal, 

Thanks for your update. 

We are glad that our solution helped you. Now we have prepared CRUD sample to save the resource field which can be downloaded from the following link. 
 
Please refer the table structure and model class for the scheduler event.

Nevitha

    };

Hi Tirathpal,  
 
Thanks for your update. 
 
In your code example, back end data is assigned to drop down via ViewBag which is correct. And DataManager also used to call the back end function, to fetch the data.
