add/update reminder on a existing appointment in scheduler

[envy kok]

Hello

I am currently using 2011 Q2 version. Is it this version support add/update reminder on a existing appointment in scheduler?

Here is my setting, but I am not able to add & update reminder. Or do I need to add code behind?

 <telerik:RadScheduler ID="RadScheduler1" runat="server" 
        DataDescriptionField="Description" DataEndField="End" DataKeyField="ID" 
        DataRecurrenceField="RecurrenceRule" 
        DataRecurrenceParentKeyField="RecurrenceParentID" DataReminderField="Reminder" 
        DataSourceID="EntityDataSource1" DataStartField="Start" 
        DataSubjectField="Subject" EnableDescriptionField="True" Height=""
        Reminders-Enabled="true">
        <ResourceTypes>
            <telerik:ResourceType DataSourceID="EntityDataSource2" 
                ForeignKeyField="TestResourceId" KeyField="Id" Name="Resource Type 0" 
                TextField="Description" />
        </ResourceTypes>
            <AdvancedForm Modal="true" />
            <Reminders Enabled="true" />
            <TimeSlotContextMenuSettings EnableDefault="true" />
            <AppointmentContextMenuSettings EnableDefault="true" />
    </telerik:RadScheduler>
    <asp:EntityDataSource ID="EntityDataSource2" runat="server" 
        ConnectionString="name=IAppointmentEntities" 
        DefaultContainerName="IAppointmentEntities1" EnableFlattening="False" 
        EntitySetName="TestResources">
    </asp:EntityDataSource>
    <asp:EntityDataSource ID="EntityDataSource1" runat="server"
