Remarks

Selecting a period

To select a period :

in a Calendar control, the option "Period selection" must be selected in the "Details" tab of the Calendar control.
in an Organizer control, the option "Allow the selection of periods" must be selected in the "Details" tab of Organizer control.
in a Scheduler control, the option "Allow the selection of periods" must be selected in the "Details" tab of Scheduler control.

Modifying a period in a Calendar, Organizer or Scheduler control

To modify the start date of a selected period, you must specify the start date (..StartDate) and the end date of the period (..EndDate). Indeed, the modification of the start date:

automatically deselects the end date.
waits for the end date to be selected (by programming or via a click on a control date).

To modify the end date of a selected period, all you have to do is use ..EndDate: the period is automatically modified.

Special cases

The end date of a period is returned and modified by ..EndDate.
..StartDate returns the start date of the period according to the chronological order. Therefore, if the end date was selected before the start date, ..StartDate will return the last date that was selected.
In a Scheduler control, ..StartDate can only be used to find out the start date of the period. This date cannot be modified.
