Server-Side Event Handling

Examples

Example 1: Event move handler

MVC View

@Html.DayPilotCalendar("dpc", new DayPilotCalendarConfig
{
  BackendUrl = ResolveUrl("~/Calendar/Backend"),
  EventMoveHandling = EventMoveHandlingType.CallBack
})

MVC Controller

[HandleError]
public class CalendarController : Controller
{

  public ActionResult Backend()
  {
      return new Dpc().CallBack(this);
  }

  public class Dpc : DayPilotCalendar
  {
      protected override void OnEventMove(DayPilot.Web.Mvc.Events.Calendar.EventMoveArgs e)
      {
          new EventManager(Controller).EventMove(e.Id, e.NewStart, e.NewEnd);
          Update();
      }

      protected override void OnFinish()
      {
          // only load the data if an update was requested by an Update() call
          if (UpdateType == CallBackUpdateType.None)
          {
              return;
          }

          // this select is a really bad example, no where clause
          Events = new EventManager(Controller).Data.AsEnumerable();

          DataStartField = "start";
          DataEndField = "end";
          DataTextField = "name";
          DataIdField = "id";


          // optional
          DataAllDayField = "allday";
          DataTagFields = "id, name";

      }

  }
}

Example 2: Using Command event to refresh the events

See also CommandCallBack.

MVC View

<div><a href="dpc.commandCallBack('refresh')">Refresh</a></div>

@Html.DayPilotCalendar("dpc", new DayPilotCalendarConfig
{
  BackendUrl = ResolveUrl("~/Calendar/Backend")
})

MVC Controller

[HandleError]
public class CalendarController : Controller
{

  public ActionResult Backend()
  {
      return new Dpc().CallBack(this);
  }


  public class Dpc : DayPilotCalendar
  {

      protected override void OnCommand(CommandArgs e)
      {
          switch (e.Command)
          {

              case "refresh":
                  Update(CallBackUpdateType.EventsOnly);
                  break;
          }
      }

      protected override void OnFinish()
      {
          // only load the data if an update was requested by an Update() call
          if (UpdateType == CallBackUpdateType.None)
          {
              return;
          }

          // this select is a really bad example, no where clause
          Events = new EventManager(Controller).Data.AsEnumerable();

          DataStartField = "start";
          DataEndField = "end";
          DataTextField = "name";
          DataIdField = "id";
          
          // optional
          DataResourceField = "resource";
          DataAllDayField = "allday";
          DataTagFields = "id, name";

      }
  }
}
