Event in older date - Scheduler Lite

Hi,
I'm trying to load events for an past date. For do this, I'm doing:

DayPilotScheduler1.StartDate = DateTime.Parse("06-06-2012");
DayPilotScheduler1.DataSource = getData();

But when I go to the page the datas were loaded in the today section.

How I can load on my desidered date?

Thanks
