How can I get/set the firstdate and lastdate selected in a tplannercalendargroup?
Selected dates are get/set via PlannerCalendarGroup.Dates collection.
First and last date are access via the first/last item of this PlannerCalendarGroup.Dates collection.
To set a range of selected dates:
PlannerCalendarGroup1.Dates.Clear;
PlannerCalendarGroup1.Dates.AddRange(Now, Now +10);
PlannerCalendarGroup1.UpdateDates;
