The AppointmentCancelingEdit event occurs when the user clicks the cancel button of the in-line editor or the edit form.

AppointmentCancelingEdit has two parameters:

  • sender is the scheduler control.

  • e is an object of type AppointmentCancelingEditEventArgs. It has three properties:

  • Appointment is the appointment that was being inserted or updated by the editor.

  • Container is the editor that was being used to insert or edit an appointment.

  • Cancel is a boolean value that lets you prevent the user from exiting the edit form or in-line editor.


protected void RadScheduler1_AppointmentCancelingEdit(object sender, AppointmentCancelingEditEventArgs e)
    if (e.Appointment.Subject == String.Empty)
        e.Cancel = true;

Sub RadScheduler1_AppointmentCancelingEdit(ByVal sender As Object, _
                        ByVal e As AppointmentCancelingEditEventArgs) _
                     Handles RadScheduler1.AppointmentCancelingEdit
    If e.Appointment.Subject = String.Empty Then
        e.Cancel = True
    End If
End Sub
