Namespace: DevExpress.Web.ASPxScheduler

Assembly: DevExpress.Web.ASPxScheduler.v18.1.dll

Declaration

C#

[Browsable(false)]
public event PersistentObjectCancelEventHandler AppointmentDeleting

VB.NET

<Browsable(False)>
Public Event AppointmentDeleting As PersistentObjectCancelEventHandler

Event Data

The AppointmentDeleting event's data class is PersistentObjectCancelEventArgs. The following properties provide information specific to this event:

Property	Description
Cancel	Gets or sets whether to cancel the operation.
Object	Gets the persistent object (appointment, resource or appointment dependency) for which the event occurs. Inherited from PersistentObjectEventArgs.

Remarks

The AppointmentDeleting event is raised before an appointment is deleted and allows you to cancel the deletion of an appointment. The event parameter’s PersistentObjectEventArgs.Object property allows the processed appointment to be identified. To prevent it from being deleted, set the PersistentObjectCancelEventArgs.Cancel property to true.

Important

Do not modify a persistent object for which the event is raised in the event handler’s code.

The following example illustrates how to access custom fields of a currently deleted appointment within the AppointmentDeleting event.

C#

protected void ASPxScheduler1_AppointmentDeleting(object sender, DevExpress.XtraScheduler.PersistentObjectCancelEventArgs e) {
    Appointment currentAppointment = e.Object as Appointment;
    if(currentAppointment.CustomFields["SomeCustomFieldValue"].ToString() == "disabled") {
        e.Cancel = true;
    }
}
