I've created a ObjectDataset for Appointments datasource and another for ResourceDatasource. I have mapped columns for ASPxScheduler and assigned datasources too. But no data is appearing on scheduler view. What are the troubleshooting options?

 ASPX code for the scheduler is as follows: 

         <dxwschs:ASPxScheduler runat="server" ActiveViewType="Timeline" Views-DayView-Enabled="false"
            Views-WeekView-Enabled="false" Views-WorkWeekView-Enabled="false" Views-MonthView-Enabled="false"
            ClientInstanceName="scheduler" ID="scheduler" Width="100%" Start="2008-01-01"
            Font-Names="Tahoma" Font-Size="8pt" AppointmentDataSourceID="odsScheduler" ResourceDataSourceID="odsResource">
            <Storage EnableReminders="false">
                <Appointments>
                    <Mappings AppointmentId="UniqueID" Description="Description" End="EndDate" Label="Label"
                        Location="Location" Start="StartDate" Subject="Subject" Type="UnitType" Status="Status"
                        AllDay="AllDay" RecurrenceInfo="RecurrenceInfo" ReminderInfo="ReminderInfo" ResourceId="UnitId" />
                </Appointments>
                <Resources>
                    <Mappings Caption="MU_CODE" ResourceId="MU_ID" />
                </Resources>
            </Storage>
            <OptionsView FirstDayOfWeek="Sunday">
            </OptionsView>
            <Views>
                <DayView Enabled="False">
                    <TimeRulers>
                        <cc1:TimeRuler>
                        </cc1:TimeRuler>
                    </TimeRulers>
                </DayView>
                <WorkWeekView Enabled="False">
                    <TimeRulers>
                        <cc1:TimeRuler>
                        </cc1:TimeRuler>
                    </TimeRulers>
                </WorkWeekView>
                <WeekView Enabled="False">
                </WeekView>
                <MonthView Enabled="False">
                </MonthView>
                <TimelineView ShortDisplayName="Temporary Leasing">
                    <AppointmentDisplayOptions AppointmentAutoHeight="True" />
                </TimelineView>
            </Views>
        </dxwschs:ASPxScheduler>
        <asp:ObjectDataSource ID="odsScheduler" runat="server" OldValuesParameterFormatString="original_{0}"
            SelectMethod="GetData" TypeName="DAL.SchedulerDataSetTableAdapters.SchedulerAdapter">
        </asp:ObjectDataSource>
        <asp:ObjectDataSource ID="odsResource" runat="server" OldValuesParameterFormatString="original_{0}"
            SelectMethod="GetData" TypeName="DAL.SchedulerDataSetTableAdapters.ResourceAdapter">
        </asp:ObjectDataSource>
