Occurs before an AppointmentImporter class descendant imports an appointment from an iCalendar file.

Namespace: DevExpress.XtraScheduler.Exchange

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

Declaration

C#

public event AppointmentImportingEventHandler AppointmentImporting

VB.NET

Public Event AppointmentImporting As AppointmentImportingEventHandler

Event Data

The AppointmentImporting event's handler receives an argument of the AppointmentImportingEventArgs type. The following properties provide information specific to this event:

Property	Description
Appointment	Gets the appointment for which the event was raised. Inherited from AppointmentEventArgs.
Cancel	Gets or sets whether the operation performed on the processed event should be canceled. Inherited from AppointmentCancelEventArgs.

Remarks

Handle the AppointmentImporting event when implementing custom appointment import procedures. It enables you to decide what to do if conflicting items are found, and select which appointments should be imported.

To know more about iCalendar support, refer to the corresponding iCalendar Support article.

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
