AppointmentCancelEventArgs Class

Serves as the base class for classes which provide data for certain appointment events with the ability to cancel the operation being performed.

Namespace: DevExpress.XtraScheduler

Assembly: DevExpress.XtraScheduler.v14.2.Core.dll

Declaration

C#

public class AppointmentCancelEventArgs :
    AppointmentEventArgs

VB.NET

Public Class AppointmentCancelEventArgs
    Inherits AppointmentEventArgs

Remarks

The AppointmentCancelEventArgs class introduces the AppointmentCancelEventArgs.Cancel property which specifies whether the operation performed on the processed event should be cancelled.

Note that AppointmentCancelEventArgs objects are automatically created, initialized and passed to the corresponding event handlers.

Examples

This example demonstrates how to import only non-recurring appointments to the scheduler control from the iCalendar format. To perform such custom import operations, handle the AppointmentImporter.AppointmentImporting event and use the AppointmentCancelEventArgs.Cancel property.

C#

using System.IO;
using DevExpress.XtraScheduler;
using DevExpress.XtraScheduler.iCalendar;
// ...

private void ImportAppointments(Stream stream) {
    if (stream == null || Stream.Null.Equals(stream))
        return;
    iCalendarImporter importer = new iCalendarImporter(schedulerControl1.GetCoreStorage());
    importer.AppointmentImporting += new AppointmentImportingEventHandler(importer_AppointmentImporting);
    importer.Import(stream);
}

void importer_AppointmentImporting(object sender, AppointmentImportingEventArgs e) {
    if (e.Appointment.IsRecurring) {
        e.Cancel = true;
    }
}

VB.NET

Imports System.IO
Imports DevExpress.XtraScheduler
Imports DevExpress.XtraScheduler.iCalendar
' ...

Private Sub ImportAppointments(ByVal stream As Stream)
    If stream Is Nothing OrElse Stream.Null.Equals(stream) Then
        Return
    End If
    Dim importer As New iCalendarImporter(schedulerControl1.GetCoreStorage())
    AddHandler importer.AppointmentImporting, AddressOf importer_AppointmentImporting
    importer.Import(stream)
End Sub

Private Sub importer_AppointmentImporting(ByVal sender As Object, ByVal e As AppointmentImportingEventArgs)
    If e.Appointment.IsRecurring Then
        e.Cancel = True
    End If
End Sub
