Issue in updating delete status of reccurring appointment

[roshani]

Hello Admin,

I have used Telerik scheduler. Following is the code that I am using to update the delete status of the appointment

protected void rsAppointments_OnAppointmentDelete(object sender, AppointmentDeleteEventArgs e)
       {
           try
           {
               Appointment appToEdit = rsAppointments.PrepareToEdit(e.Appointment, rsAppointments.EditingRecurringSeries);
               appToEdit.Attributes["IsDeleted"] = "1";

               rsAppointments.UpdateAppointment(appToEdit);
               ScriptManager.RegisterStartupScript(Page, GetType(), "alert", "alert('Appointment deleted successfully');", true);
               ViewState["Deleted"] = "1";
               // upScheduler.Update();
           }
           catch (Exception ex)
           {
               string ErrorMessage = ex.Message;
               SysLog.LogException(ex, MessageTypeEnum.DatabaseException, MessageSeverityEnum.Error);
           }
       }

 Actually before updating the website with the developer version this code was working fine for both recurring and non-recurring appointments. But after deploying the developer version, When I tried to delete the a nonreccurring appointment this works fine and when i tried to delete  an occuerrence  the update appointment event is fired directly. Control does not hit this code while deleting the occurence. Hence it just update the master appointment by adding the exception in the reccurrencerule but it doesn't insert this occurrence as new appointment. I was doing the final testing for the project. Everything was working fine with the trial version n now getting this strange behavior after adding the developer version. While deleting nonreccuring appointments or series it hits the AppointmentDelete event first but while deleting the occurrnece it is hitting to the AppointmentUpdate event directly.
Please provide your guidance as soon as possible.. Its urgent.

Thanks,
Roshani

Also one more issue I noticed is :

I created a reccurring appointment and updated it using edit reccurring series. After this i tried  to update the status of an occurence by using the button on the appointment template, It automatically updates the status for the whole series instead of creating exception for the occurence and then inserting it. Also If I created a reccuerence appointment and directly click on the button then it cretes an exception for that occurence and then insert it in the databse which is very expected behaviour. But as told earlier this is not happening in case if i update the reccuring appointment as "Edit whole series" before performing these operations. I have used AppointmentCommand event.

I just want to update the that occurence only..

Hi roshani,

You can use OccurrenceDelete server side event of RadScheduler.

Hi,

I am using the OccurrenceDelete event to delete a single occurrence. The event fires, we get the modified RecurrenceRule and store it in a database. The GUI updates. However if we close the browser and then re-run, the occurrence is present.

The recurrence string we are getting from the appointment is this, which does not appear to have enough information for an exception date
DTSTART:20110517T000000Z
DTEND:20110518T000000Z
RRULE:FREQ=WEEKLY;INTERVAL=1;BYDAY=TU
EXDATE:2011

Any thoughts on what we are doing wrong? Also, interesting to note that once the OccurrenceDelete event fires, the Update event files right after that. Not the behavior we expected. Any help welcome. Thanks!

Hi Karl,

AppointmentUpdate needs to also fire because the master appointment updates its recurrence rule with the exception created. AppointmentUpdate is also the event which you need to get the correct recurrence rule with e.ModifiedAppointment.RecurrenceRule.
