Hi Nagi,

Thank you for your question. While searching for a solution, we discovered a limitation of RadScheduler which prevents an easy implementation for this scenario. 

The good news is that there is a workaround you can try. Please, consider the iCalendar Export online example. The content of the iCalendar file has the following format for its content when viewed in a text editor:

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//Telerik Inc.//NONSGML RadScheduler//EN
METHOD:PUBLISH
BEGIN:VEVENT
DTSTART:20070330T063000Z
DTEND:20070330T073000Z
RRULE:FREQ=DAILY;UNTIL=20070406T073000Z;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR
UID:20080103T132558Z-15
DTSTAMP:20080103T132558Z
SUMMARY:Technical meeting
END:VEVENT
*   *    *    *    *
BEGIN:VEVENT
DTSTART:20070329T210000Z
DTEND:20070330T210000Z
UID:20080103T132558Z-27
DTSTAMP:20080103T132558Z
SUMMARY:Alex's Birthday
END:VEVENT
END:VCALENDAR

The challenge is to create a string with similar formatting based on the appointments in the visible range of RadScheduler and pass it to the WriteCalendar() method. We came up with the following solution -

Button2_Click event handler:

protected void Button2_Click(object sender, ImageClickEventArgs e)
        {
            //WriteCalendar(RadScheduler.ExportToICalendar(RadScheduler1.Appointments));

            StringBuilder visibleAppointments = new StringBuilder();
            foreach (Appointment a in RadScheduler1.Appointments.GetAppointmentsInRange(RadScheduler1.VisibleRangeStart, RadScheduler1.VisibleRangeEnd))
            {
                string appointmentDetails = RadScheduler.ExportToICalendar(a);

                string appointmentDetailsTrimmed = appointmentDetails.Replace("BEGIN:VCALENDAR\r\nVERSION:2.0\r\nPRODID:-//Telerik Inc.//NONSGML RadScheduler//EN\r\nMETHOD:PUBLISH\r\n", "");
                appointmentDetailsTrimmed = appointmentDetailsTrimmed.Replace("\r\nEND:VCALENDAR", "");
                visibleAppointments.Append(appointmentDetailsTrimmed);
            }

            visibleAppointments.Insert(0, "BEGIN:VCALENDAR\r\nVERSION:2.0\r\nPRODID:-//Telerik Inc.//NONSGML RadScheduler//EN\r\nMETHOD:PUBLISH\r\n");
            visibleAppointments.Append("END:VCALENDAR");
            WriteCalendar(visibleAppointments.ToString());
        }

This is helpful. Thanks, but sure would like an easier way to populate more properties using the appointment item directly.
