Thank you for writing back.
This property is used when adding an exception in the events recurrence sequence (the appointment in the exception collection) and it is also used in the export to ICall format. It is referenced in the following classes: AppointmentMappingInfo, MappingInfoDialog, SchedulerICalendarExporter, SchedulerUIHelper, SchedulerInplaceEditorControl, SchedulerView and EditAppointmentDialog classes.
You can download the source code of our controls in order to debug the exception that you received and to access the code where this property is used. The source code is available only for our customer, not for trial users. You can download it by following these steps:
- Login to your account
- Click on Products and Subscriptions > DevCraft Complete
- Click on Download installer and other resources button on the right
- Click on Browse all product files link in the RadControls for Winforms pane
- Click the Source code link
Also, you can build the assemblies for the source code and you will be able to produce a stack trace when the error occurs.
I hope this helps.
All the best,
the Telerik team
