Hello telerik,

in my current Silverlight 5 project I am using the SchduleView and unfortunately the program crashes EVERYTIME, when the user changes the size of the containing window. I tried to reduce the xaml to get this error and I'll get this error now with just a few lines of code and some mouse movements/ resizings of the window. Here's the code:
<telerik:RadScheduleView x:Name="MinimapSchedule" Grid.Row="1" Grid.Column="1" MinAppointmentHeight="20"
                                             NavigationHeaderVisibility="Collapsed" Height="20">
                <telerik:RadScheduleView.ActiveViewDefinition>
                    <telerik:TimelineViewDefinition MinTimeRulerExtent="1" MaxTimeRulerExtent="Infinity" ShowTimeRuler="False"
                                                    StretchAppointments="True" StretchGroupHeaders="True" MinorTickLength="1month" MajorTickLength="1month">
                    </telerik:TimelineViewDefinition>
                </telerik:RadScheduleView.ActiveViewDefinition>
            </telerik:RadScheduleView>

That's all! A blank project with the latest telerik assemblies and this code in the MainPage.xaml - soon you'll get the "Layout cycle detected. Layout could not complete" exception! With soon I mean, that you have to change the window size a little bit. With this xaml the exception is not thrown on every resize but it is still easy; change the width, height, maximize, minimize, ...

Is it possible to fix this? Currently I am definitly not able to use the Scheduler...
Thanks a lot for any input and advice,
Tim.

It looks like the issue can be avoided by setting the VerticalScrollBarVisibility to true. We alway got this issue when the scheduler shrunk to a size where it needed a scrollbar, with the scrollbar always visible I haven't seen this issue again.

Hello,

The problem occur when the ScrollViewer show and disappear, so indeed this issue can be workarounded by making it show all the time by setting VerticalScrollBarVisibility to true.
