RelativeSource.PreviousData Property

Gets a static value that is used to return a RelativeSource constructed for the PreviousData mode.

Namespace:  System.Windows.Data
Assembly:  PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

public static RelativeSource PreviousData { get; }
For XAML information, see RelativeSource MarkupExtension.

Three of the four RelativeSourceMode values, PreviousData, Self, or TemplatedParent, can produce a RelativeSource that is wholly static, containing no unique private values. All uses of the static property can share the same object, eliminating the need to allocate separate objects for each use. Therefore, using the static property reduces memory usage.
