Indeed as our other response says RadScheduleView control is designed to use its own scroll bars and placing it in ScrollViewer control may cause some unexpected behaviors.
In your scenario if you know the height of the ScrollViewer that you want to place the ScheduleView control in you could set the Height
property of the two control to the same value and set the VerticalScrollBarVisibility
property of the ScrollViewer to Hidden. That would force the ScheduleView control to show its own scroll back because the Height of the outer control is lower then what is need to render its content. As the other response mentioned by placing the ScheduleView in a ScrollViewer control the main drawback is that all virtualized panels will stop working and all visual items will be realized when the ScheduleView control is loaded which may cause performance issues.
