You can specify the week date using StartDate property.
It is accessible in the config (DayPilotCalendarConfig class):
@Html.DayPilotCalendar("dpc", new DayPilotCalendarConfig {
BackendUrl = Url.Content("~/Calendar/Backend"),
ViewType = DayPilot.Web.Mvc.Enums.Calendar.ViewType.Week,
StartDate = new DateTime(2015, 1, 1),
// ...
})
and also in the backend class:
protected override void OnInit(InitArgs e)
{
StartDate = new DateTime(2015, 1, );
// ...
Update(CallBackUpdateType.Full);
}
