Occurs when an end-user tries to create a new appointment and the SchedulerOptionsCustomization.AllowAppointmentCreate property is set to Custom.
public event AppointmentOperationEventHandler AllowAppointmentCreate
Public Event AllowAppointmentCreate As AppointmentOperationEventHandler
The AllowAppointmentCreate event's data class is AppointmentOperationEventArgs. The following properties provide information specific to this event:
|Allow||Gets or sets a value indicating whether an end-user is allowed to perform a particular action.|
|Appointment||Gets the appointment for which the event was raised. Inherited from AppointmentEventArgs.|
|Recurring||Gets or sets a value indicating if the appointment is recurring.|
Handle the AllowAppointmentCreate event to manually decide whether to allow an end-user to create a new appointment or not. To prevent an appointment from being created, set the AppointmentOperationEventArgs.Allow property to false. The AppointmentEventArgs.Appointment property for this event always contains null, so check the SchedulerViewBase.SelectedInterval or use other criteria to make a desicion.
The AllowAppointmentCreate event is fired only if the SchedulerOptionsCustomization.AllowAppointmentCreate property is set to UsedAppointmentType.Custom.
