Problem in Views:Month ok but Day and Week is empty

[samin]

Hi,
I use ScheduleView control from 2012 Q1 package, thank you for your effort to improve your product package by package.

generally I use MonthViewDefenition in my product. but earlier I need other view like day and week , below you can see my instance definition

<telerik:RadScheduleView HorizontalAlignment="Left"  FontFamily="Tahoma" ActiveViewDefinitionIndex="0" Name="radScheduleView1" VerticalAlignment="Top">
            <telerik:RadScheduleView.ViewDefinitions>
                <telerik:DayViewDefinition/>
                <telerik:WeekViewDefinition/>
                <telerik:MonthViewDefinition/>
            </telerik:RadScheduleView.ViewDefinitions>
        </telerik:RadScheduleView>

It doesn't work truly in Day and week view definition, and there not appointment in view but in month view every thing is in order.
is there any special bug in these view??

I made a mistake. cause of wrong start and date time in my appointment source.
So. there is no problem ;)
