DayPilot.Scheduler.onEventMoveStart

The onEventMoveStart event handler fires when the user starts dragging an event during event moving in the JavaScript Scheduler.

Available since 2025.4.6723.

Declaration

DayPilot.Scheduler.onEventMoveStart(args)

Parameters

• args.ctrl (boolean) - Ctrl key pressed

• args.shift (boolean) - Shift key pressed

• args.meta (boolean) - Meta key pressed

• args.alt (boolean) - Alt key pressed

• args.areaData - value of the data property of the active area used as the drag handle

• args.e (DayPilot.Event) - source object

• args.external (boolean) - true when the event comes from an external source
