Custom Drag & Drop

Appointment drag and drop is enabled out-of-the-box, but only if appointments are moved within the Scheduler. In this demo, appointments can be moved between the Scheduler and a list.

Backend API
$(() => { const draggingGroupName = 'appointmentsGroup'; const createItemElement = function (data) { $('<div>') .text(data.text) .addClass('item dx-card') .appendTo('#list') .dxDraggable({ group: draggingGroupName, data, clone: true, onDragEnd(e) { if (e.toData) { e.cancel = true; } }, onDragStart(e) { e.itemData = e.fromData; }, }); }; $('#scroll').dxScrollView({}); $('#list').dxDraggable({ data: 'dropArea', group: draggingGroupName, onDragStart(e) { e.cancel = true; }, }); tasks.forEach((task) => { createItemElement(task); }); $('#scheduler').dxScheduler({ timeZone: 'America/Los_Angeles', dataSource: appointments, views: [{ type: 'day', intervalCount: 3, }], currentDate: new Date(2021, 3, 26), startDayHour: 9, height: 600, editing: true, appointmentDragging: { group: draggingGroupName, onRemove(e) { e.component.deleteAppointment(e.itemData); createItemElement(e.itemData); }, onAdd(e) { e.component.addAppointment(e.itemData); e.itemElement.remove(); }, }, }); });

Follow the steps below to implement this functionality:

  1. Configure the Scheduler
    In the appointmentDragging object, implement the onAdd function (in which you should add an appointment) and the onRemove function (in which you should delete an appointment and create a corresponding list item).

  2. Configure list items
    Attach an instance of the Draggable component to every list item. The component has the data property that can contain custom data. In this demo, it is an appointment's subject. Implement the onDragStart function in which you should pass the subject to the Scheduler where it is used to add new appointments.

  3. Configure the list
    Attach another Draggable instance to the list which only serves as the drop target. Implement the onDragStart function to ensure the list cannot be dragged.

  4. Add the controls to the same group
    To enable drag and drop operations between the controls, assign the same value to the group property of the Scheduler's appointmentDragging object and both Draggable components.
