Definition
Important

Gets a static value that is used to return a RelativeSource constructed for the PreviousData mode.
public:
static property System::Windows::Data::RelativeSource ^ PreviousData { System::Windows::Data::RelativeSource ^ get(); };
public static System.Windows.Data.RelativeSource PreviousData { get; }
static member PreviousData : System.Windows.Data.RelativeSource
Public Shared ReadOnly Property PreviousData As RelativeSource
Property Value
A static RelativeSource.
Remarks
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.
