This demo illustrates the use of a custom popup menu command to export selected appointments to the file in iCalendar format. It employs the iCalendarExporter Constructor, which takes a collection of appointments for export.
Select several appointments by clicking them while holding the Ctrl key. Hover over one of them for the smart tag to appear. Click the smart tag and select the Export command in the context menu.
