DevExtreme Scheduler raises the onSelectionEnd event when a user selects cells. The event's selectedCellData array contains one object per selected cell, each with startDate, endDate, allDay, and group field values.
In this sample, the event handler ignores single-cell selection and passes a new appointment object built from the first and last cell in the selection to the showAppointmentPopup method.
