Meppy,

Sorry!  Out test team are reporting an intermittent error when removing an appointment from the calendar.

This does not happen everytime an appointment is deleted.  This issue never happened before the latest patch.

Here is the error as logged:

Cannot remove the specified item because it was not found in the specified Collection.
   at System.Collections.CollectionBase.System.Collections.IList.Remove(Object value)
   at MindFusion.Scheduling.ItemCollection.Remove(Item item)
   at MindFusion.Scheduling.WinForms.Calendar.OnKeyDown(KeyEventArgs e)

   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)

Thanks for your help.

Hi,

Yes, the Calendar is set to a TimeTable view.
The ItemDeleted event is used to discover which appointment is being deleted. We used the e.Item property to get information about the appointment so we can update our own appointment database.

It is not a recurring appointment.

This is the code I have in the ItemDeleted method:

protected virtual void calendar_ItemDeleted(object sender, MindFusion.Scheduling.WinForms.ItemEventArgs e)
{
Appointment appointment = e.Item as Appointment;
AppointmentCore coreAppointment = e.Item.Tag as AppointmentCore;
SelectedCalendar.RemoveAppointment(coreAppointment);
RefreshUIAppointments();

CallOnCalendarChange();
}

It uses the .Tag property of the appointment which holds our own Appointment object. the RemoveAppointment method removes our own Appointment object, not the Mindfusion Appointment.

I will be trying to recreate the problem and will post more information if I get it. 

Thanks
Michael

Yes, I have been tracing through the code.
ItemDeleting fires correctly, then occasionally the application will crash before ItemDeleted is called.

I am continuing to investigate what might be causing the issue, in case it is something my end.

Thanks
Michael

I think I have found what causes the problem.

I am manually selecting an item by adding it to the ItemSelection collection.  If I don't do this, then the problem does not occur.

Is there a problem with this method I am using, or should I be using a different method?

Thanks
Michael.
