10                 Control authors who want to customize the arrange pass of layout processing should override this method. The implementation pattern should call M:System.Windows.UIElement.Arrange(System.Windows.Rect) on each visible child element, and pass the final desired size for each child element as the finalRect parameter. Parent elements should call M:System.Windows.UIElement.Arrange(System.Windows.Rect) on each child, otherwise the child elements will not be rendered.
11 Many derived classes offer implementations of this method. Prominent ones include: M:System.Windows.Window.ArrangeOverride(System.Windows.Size), M:System.Windows.Controls.Page.ArrangeOverride(System.Windows.Size) and M:System.Windows.Controls.Control.ArrangeOverride(System.Windows.Size).
