RadScheduler Contol Delete Event gets Fired Twice...

[Mayur]

Hello,

I have below RadScheduler control on my page. Code as below:

<asp:Content ID="Content1" ContentPlaceHolderID="main" runat="Server">
    <telerik:RadScheduler runat="server" ID="schedular" DataKeyField="ID" DataSubjectField="Subject"
        DataStartField="Start" DataEndField="End" StartEditingInAdvancedForm="true" DataRecurrenceField="RecurrenceRule"
        DataRecurrenceParentKeyField="RecurrenceParentID" OnAppointmentInsert="schedular_AppointmentInsert"
        OnAppointmentDelete="schedular_AppointmentDelete" StartInsertingInAdvancedForm="true">
    </telerik:RadScheduler>
</asp:Content>

I can insert the appointment easily but when I delete the appointment the Delete event (OnAppointmentDelete = "schedular_AppointmentDelete") gets Fired twice.

If I remove the recurrence properties (i.e.DataRecurrenceField, DataRecurrenceParentKeyField) then it works fine but I need Recurrence functionality.

Please let me know the solution to this problem.

Thanks,
Mayur.

Hi,

I'm also facing the same issue.
Can anyone provide a solution to this issue?? I'll be thank full.

Hello Azia,

I did not manage to reproduce this behavior locally. When I delete a non-recurrent appointment, the OnAppointmentDelete event fires only once. When deleting a recurrent appointment, the same event fires only when the whole series of the appointments is deleted, it  does not fire if a single occurrence is deleted.

If you are still having troubles, could you please send us a support ticket, where a sample page could be attached to the message. Please provide us with a runnable web page, so I will be able to troubleshoot this behavior locally.

Best wishes,

Hi Mayur.
I also had this happening to me.
I found out that since I specify the sub to handle the delete in my ASPX file, that I did NOT need to  add the 'Handles schedular.AppointmentDelete' at the end of the SUB in my code behind file.

I removed 'Handles schedular.AppointmentDelete'  from the end of my SUB and my event only fires once now.

So if it looks like this...
Protected Sub scheduler_AppointmentDelete(sender As Object, e As Telerik.Web.UI.AppointmentDeleteEventArgs) Handles schedular.AppointmentDelete

make it looks like this...
Protected Sub scheduler_AppointmentDelete(sender As Object, e As Telerik.Web.UI.AppointmentDeleteEventArgs)

Now my delete event only fires once.
Not sure if this is your problem, but I figured I would mention it.
Good luck!

Hi Mayur,

I still could not produce the same behavior, locally. I have tested your code in a content page, which has nothing declared in its master page, except for the RadScriptManager definition. Everything works fine with the Scheduler and the server-side events are fired as expected.

You could take a look at the video linked below, to see how the scheduler behaves at my end:
RadScheduler: OnAppointmentDelete.
