So I don't know how to get correct value (Start Time, End Time) for this appointment , that have choice to modify ?

I'm expecting for your reply with my problem !

Hi Nguyen,

When working with recurrent appointments, please consider the following:

RadScheduler includes support for recurring events on hourly, weekly, daily, monthly and yearly basis. Exceptions to the recurrence rules are supported. This article provides an overview of the architecture and more examples and information can be obtained from the API reference.

To implement recurrence support the Appointment class includes the RecurrenceRule, RecurrenceParentID and RecurrenceState properties. An appointment can be made recurring either programmatically or using the advanced edit form. When an appointment is promoted into a recurring event its RecurrenceState changes to Master and the RecurrenceRule is populated with the string representation of the RecurrenceRule.

The recurrence master is stored in the database and its occurrences are generated on the fly with RecurrenceState set to Occurrence.

If the user modifies an individual appointment occurrence he creates an exception. The master is modified to include the date and time of the exception so no occurrence will be generated. Then the exception is stored in the database and its RecurrenceParentID property is set to reference the original master. This way the exception can still be linked to the original recurrence series.

Everytime you edit an individual appointment from the series and save the changes, you also insert a new appointment. If you need to capture the modified value, you should attach on the  AppointmentInsert event:

protected void RadScheduler1_AppointmentInsert(object sender, SchedulerCancelEventArgs e)
    {
        Appointment modified_ap = e.Appointment;
    }

hi peter !
Thank you very much for your help and reply !
I have just try with your help , use event :
protected void RadScheduler1_AppointmentInsert(object sender, SchedulerCancelEventArgs e)
{
           // get value for modify
}
So , It work so good !

(Because ,Previous I used event :
protected void radSchedulerTask_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)
{
  // get value for modify
}

So it's not receive correct value that had modify ! )

Thank you very much again ! :D
