How to customize the start/end time interval in cloned appointments while dragging and resizing

The following steps shows the way to customize the start and end time displayed in the cloned appointment element while dragging and resizing the appointments.

Step 1:  Create a scheduler default sample and bind the drag and resize event as shown below,  


$(function () {

            var dManager = ej.DataManager(window.Default).executeLocal(ej.Query().take(10));


                width: "100%",

                height: "525px",

                currentDate: new Date(2014, 4, 5),

                appointmentSettings: {

                    dataSource: dManager,

                    id: "Id",

                    subject: "Subject",

                    startTime: "StartTime",

                    endTime: "EndTime",

                    description: "Description",

                    allDay: "AllDay",

                    recurrence: "Recurrence",

                    recurrenceRule: "RecurrenceRule"


                drag: "cusInterval",

                resize: "cusInterval"




Step 2: Define the drag and resize event function onDrag and onResize respectively which contains the code to customize the time duration. The following code example shows the logic.

function cusInterval(args) {

            args.interval = 15; // here customized minutes can be set

Can i have the same equivalent function of onDrag for the latest version

I am getting an error in the line :

var diff = this._dragNewEndTime.getTime() - this._dragNewStartTime.getTime(); // appointment start and end time difference will be calculated

The error is "Cannot read property 'getTime' of undefined" cos when i debug the js I found out the this._dragNewEndTime is not available.
