How to: Set End-User Restrictions

  • 2 minutes to read

In some real-life applications, it might be necessary to prevent end-users from creating or editing (copy, deleting, dragging, etc.) appointments shown within the SchedulerControl. For instance, it may be necessary to show all appointments to end-users as read-only.

To implement end-user restrictions in your application, you can use the SchedulerControl.OptionsCustomization property, which provides access to the customization settings. The following restrictions are possible in the SchedulerControl.

Restriction Description
OptionsCustomization.AllowAppointmentConflicts Gets or sets a value that specifies whether an end-user is allowed to share the schedule time between two or more appointments.
OptionsCustomization.AllowAppointmentCopy Gets or sets a value that specifies whether an end-user is allowed to copy appointments.
OptionsCustomization.AllowAppointmentCreate Gets or sets a value that specifies whether an end-user is allowed to create new appointments.
OptionsCustomization.AllowAppointmentDelete Gets or sets a value that specifies whether an end-user is allowed to delete appointments.
OptionsCustomization.AllowAppointmentDrag Gets or sets a value that specifies whether an end-user is allowed to drag and drop appointments to another time slot or date.
OptionsCustomization.AllowAppointmentDragBetweenResources Gets or sets a value that specifies whether an end-user is allowed to drag and drop appointments between resources.
OptionsCustomization.AllowAppointmentEdit Gets or sets a value that specifies whether an end-user is allowed to edit appointments.
OptionsCustomization.AllowAppointmentMultiSelect Gets or sets a value that specifies whether an end-user is allowed to select more than one appointment simultaneously.
OptionsCustomization.AllowAppointmentResize Gets or set a value that specifies whether an end-user is allowed to change the time boundaries of appointments.
OptionsCustomization.AllowDisplayAppointmentForm Gets or sets the option specifying whether the Edit Appointment form can be invoked.
OptionsCustomization.AllowInplaceEditor Gets or sets a value that specifies whether an inplace editor can be activated for an appointment.

You can set a corresponding value as required, e.g., set UsedAppointmentType.None to prohibit a particular action for all appointment types, or set it to UsedAppointmentType.Recurring to allow it for recurring appointments only.

If you set one of the OptionsCustomization.Allow* properties to UsedAppointmentType.Custom, a related Allow* event will fire; you can decide how to handle any particular case in this event.

This example demonstrates how to prevent end-users from creating appointments within a certain time interval (from 2 PM to 3 PM). To implement end-user restrictions, handle the SchedulerControl.AllowAppointmentCreate event to prevent end-users from creating appointments within a certain time interval and the SchedulerControl.AllowAppointmentConflicts event to prevent an existing appointment from being dragged to the same time interval:
