Note that if the value of EnableMouseWheel is set to true, then mouse wheel events on desktop browsers are converted into DragStarted, DragDelta and DragCompleted events. Use the following code snippet to check if the event originated from a mouse wheel:

            if (e.get_nativeElementEvent().type === Leadtools.LTHelper.mouseWheelEvent) {
               // This is mouse wheel event
            }
