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
