The Notify event handler is fired when the notification queue is submitted.

Queue

The NotifyEventArgs argument holds a collection of actions (e.Queue) which should be processed one by one.

ASP.NET WebForms

See Demo/Calendar/Notify.aspx.cs.

protected void DayPilotCalendar1_Notify(object sender, DayPilot.Web.Ui.Events.Calendar.NotifyEventArgs e)
{
  foreach(DayPilotEventArgs ea in e.Queue)
  {
      if (ea is EventAddEventArgs)
      {
          EventAddEventArgs em = (EventAddEventArgs)ea;
          DayPilotCalendar1_EventAdd(sender, em);

      }
      else if (ea is EventMoveEventArgs)
      {
          EventMoveEventArgs em = (EventMoveEventArgs) ea;
          DayPilotCalendar1_EventMove(sender, em);

      }
      else if (ea is EventRemoveEventArgs)
      {
          EventRemoveEventArgs em = (EventRemoveEventArgs) ea;
          DayPilotCalendar1_EventRemove(sender, em);
      }
      else if (ea is EventUpdateEventArgs)
      {
          DayPilotCalendar1_EventUpdate(sender, (EventUpdateEventArgs) ea);
      }
  }

  string msg = String.Format("Queue saved ({0} actions).", e.Queue.Count);
  DayPilotCalendar1.UpdateWithMessage(msg);
}

ASP.NET MVC

 
protected override void OnNotify(NotifyArgs e)
{
  foreach(DayPilotArgs a in e.Queue)
  {
    if (a is EventUpdateArgs)
    {
      EventUpdateArgs updateArgs = (EventUpdateArgs) a;
      string id = updateArgs.Event.Value;
      string newText = updateArgs.New.Text;
      // update the db
    }
  }
  Update();
