Update appointment occurrence programmatically

[L]

Hello,
I have RadScheduler connected to sql server table provided by entity data source.
I want to be able to right click on an appointment or any occurrence and get a context menu that contains "Reserve" button.
Clicking "Reserve" will update a field in the related table.

I have customized the Appointment Context Menu as the following:

<AppointmentContextMenus>
                <telerik:RadSchedulerContextMenu runat="server" ID="ContextMenu1">
                    <Items>
                        <telerik:RadMenuItem Text="Edit" Value="CommandEdit" />
                        <telerik:RadMenuItem Text="Reserve" Value="Reserve" />
                    </Items>
                </telerik:RadSchedulerContextMenu>
</AppointmentContextMenus>

I handled the event of AppointmentContextMenuItemClicking

The question is: How could I update the appointment occurrence ?? taking into consideration that the occurrence doesn't has a record at the database table so I can update it. 

protected void RadScheduler1_AppointmentContextMenuItemClicking(object sender, Telerik.Web.UI.AppointmentContextMenuItemClickingEventArgs e)
   {
       if (e.MenuItem.Value == "Reserve")
       {
           // Code will go here
       }
   }

Thanks in advance

Hello,

You can use the server side API to create exception. Here is how:

protected void RadScheduler1_AppointmentContextMenuItemClicking(object sender, AppointmentContextMenuItemClickingEventArgs e)
   {
       if (e.MenuItem.Value == "Reserve")
       {
           // Code will go here
           Appointment a = RadScheduler1.Appointments.FindByID(e.Appointment.RecurrenceParentID);
           RecurrenceRule rRule = RecurrenceRule.TryParse(a.RecurrenceRule);
           rRule.Exceptions.Add(e.Appointment.Start);
           a.RecurrenceRule = rRule.ToString();

           Appointment exceptionAppointment = e.Appointment;
           exceptionAppointment.RecurrenceState = RecurrenceState.Exception;
           exceptionAppointment.Subject = "Reserved";

           RadScheduler1.InsertAppointment(exceptionAppointment);
           RadScheduler1.UpdateAppointment(a);
           RadScheduler1.Rebind();
       }
   }

Attached is a sample for reference.

Thanks Peter, Its working, I used to modify it a little to make it work with entity framework data source.
