AppointmentExporter.AppointmentExporting Event

Occurs before an Appointment Exporter exports an appointment to an iCalendar file.

Namespace: DevExpress.XtraScheduler.Exchange

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

Declaration

C#

public event AppointmentExportingEventHandler AppointmentExporting

VB.NET

Public Event AppointmentExporting As AppointmentExportingEventHandler

Event Data

The AppointmentExporting event's handler receives an argument of the AppointmentExportingEventArgs 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 AppointmentExporting event for AppointmentExporter descendants when implementing custom appointment export. It enables you to decide what to do if conflicting items are found, and select which appointments should be exported.

For more on iCalendar support, refer to the corresponding iCalendar Support article.

Examples

This example demonstrates how to export only appointments marked with the Birthday label to the iCalendar format from the scheduler. To perform such custom export operations, handle the AppointmentExporter.AppointmentExporting event and use the AppointmentCancelEventArgs.Cancel property.

C#

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

void ExportAppointments(Stream stream) {
    if (stream == null || Stream.Null.Equals(stream))
        return;
    iCalendarExporter exporter = new iCalendarExporter(schedulerControl1.GetCoreStorage());
    exporter.ProductIdentifier = "-//Developer Express Inc.//DXScheduler iCalendarExport Example//EN";
    exporter.AppointmentExporting += new AppointmentExportingEventHandler(exporter_AppointmentExporting);
    exporter.Export(stream);
}

void exporter_AppointmentExporting(object sender, AppointmentExportingEventArgs e) {
    if (e.Appointment.LabelId != 8) {
        e.Cancel = true;
    }
}

VB.NET

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

Private Sub ExportAppointments(ByVal stream As Stream)
    If stream Is Nothing OrElse Stream.Null.Equals(stream) Then
        Return
    End If
    Dim exporter As New iCalendarExporter(schedulerControl1.GetCoreStorage())
    exporter.ProductIdentifier = "-//Developer Express Inc.//DXScheduler iCalendarExport Example//EN"
    AddHandler exporter.AppointmentExporting, AddressOf exporter_AppointmentExporting
    exporter.Export(stream)
End Sub

Private Sub exporter_AppointmentExporting(ByVal sender As Object, _
                                          ByVal e As AppointmentExportingEventArgs)
    If e.Appointment.LabelId <> 8 Then
        e.Cancel = True
    End If
End Sub
