Changing a time period in a Calendar, Organizer or Scheduler control

To change the start date of a selected time period, specify the start date (StartDate property) and the end date (EndDate property). When the start date is changed:

the end date is automatically deselected.
the end date has to be selected (programmatically or by clicking a control date).

To change the end date of a selected time period, simply use the EndDate property: the time period changes automatically.

Special cases

The end date of a time period can be identified and changed with the EndDate property.
The StartDate property returns the start date of the time period in chronological order. Therefore, if the end date was selected before the start date, the StartDate property returns the last selected date.
In a Scheduler control, the StartDate property can only be used to get the start date of the time period. The date cannot be changed.
