selecting a date in the navigator

HI,

using web form ASP.NET, How can I programmatically select a date in the navigator?

What happens is if I select a date using the mouse, the navigator and the daypilotcalendar are refreshed.

but If I programmatically set the start date to today the daypilotcalendar is refreshed to today but navigator still has the yellow selection on the previously selected date

case "refresh":

DayPilotNavigator1.StartDate = DateTime.Today;

DayPilotCalendarDay.DataSource = GetData(DayPilotCalendarDay.StartDate, DayPilotCalendarDay.EndDate.AddDays(1));

DayPilotCalendarDay.DataBind();

DayPilotCalendarDay.Update();

break;

Thank you
