Definicja

Przestrzeń nazw:

System.Windows.Media.Animation

Zestaw:

PresentationCore.dll

Zwraca nieimętowaną wartość określonego DependencyPropertyelementu .

public:
 virtual System::Object ^ GetAnimationBaseValue(System::Windows::DependencyProperty ^ dp);

public object GetAnimationBaseValue (System.Windows.DependencyProperty dp);

abstract member GetAnimationBaseValue : System.Windows.DependencyProperty -> obj
override this.GetAnimationBaseValue : System.Windows.DependencyProperty -> obj

Public Function GetAnimationBaseValue (dp As DependencyProperty) As Object

Parametry

dp

DependencyProperty

Identyfikuje właściwość, której wartość podstawowa (nieimowana) powinna zostać pobrana.

Zwraca

Object

Wartość, która zostanie zwrócona, jeśli określona właściwość nie została animowana.

Implementuje

GetAnimationBaseValue(DependencyProperty)

Przykłady

W poniższym przykładzie nieimowane wartości animowanych właściwości są pobierane i wyświetlane.

Uwagi

Jeśli określona właściwość nie jest animowana, ta metoda zwraca ten sam wynik co GetValue.
