[Solved] RadScheduler not showing on Page Load

[Adam]

I am having issues where the Navigation bar is showing on PageLoad, but the rest of the calendar is not showing.  I have EnableViewState set to true.   The RadScheduler is inside a .ascx control.  If I click on anything in the calendar's Navigation Bar, I get the rest of the calendar to pop up.  Is there something else that I need to do?  Below is how I have the UpdatePanel defined and how the RadScheduler is defined...

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true">
                    <ContentTemplate>
                        <telerik:RadScheduler Width="850" Height="600" ID="VMDSCalendarEvents" runat="server" FirstDayOfWeek="Sunday" SelectedView="MonthView"
                                              WorkDayStartTime="7" EnableAdvancedForm="true" AllowInsert="true" TimelineView-ReadOnly="true"
                                              OnAppointmentDataBound="VMDSCalendarEvents_OnAppointmentDataBound" OnAppointmentCommand="VMDSCalendarEvents_OnAppointmentCommand"
                                              OnAppointmentInsert="VMDSCalendarEvents_OnAppointmentInsert" OnAppointmentDelete="VMDSCalendarEvents_OnAppointmentDelete"
                                              OnAppointmentUpdate="VMDSCalendarEvents_OnAppointmentUpdate" OnFormCreated="VMDSCalendarEvents_OnFormCreated" >

This RadScheduler was in a Tab that was hidden on page load.  When I moved the tab to be the first one that is open when the page is loaded, everything worked fine.
