Question

I have a ASPXShceduler binded with object data source. It work fine, but when I change it to past and try to delete or update ObjectDataSource methods are not fired. When I change if back again it works… Any idea what is the problem?

<dxwschs:ASPxScheduler 
                ID="AppointmentsSchaduler" 
                ClientInstanceName="AppointmentsSchaduler"
                runat="server" 
                AppointmentDataSourceID="AppointmentsDataSource" 
                ActiveViewType="TimeLine">
                <Storage EnableReminders="False">
                    <Appointments>
                        <Mappings AppointmentId="ID" Subject="Caption" Description="Note" Label="MarkAsDone"
                            Start="StartDate" End="EndDate" />
                        <labels>
                            <dxwschs:AppointmentLabel Color="255, 194, 190" DisplayName="Not Done" MenuCaption="&amp;Not Done" />
                            <dxwschs:AppointmentLabel Color="193, 244, 156" DisplayName="Done" MenuCaption="&amp;Done"  />
                        </labels>
                    </Appointments>
                </Storage>
            </dxwschs:ASPxScheduler>
