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). The modification of the start date:
  • 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 start date of a time period can be identified and changed with the StartDate 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.
