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 -> objPublic Function GetAnimationBaseValue (dp As DependencyProperty) As ObjectParameters
Identifies the property whose base (non-animated) value should be retrieved.
Returns
The value that would be returned if the specified property were not animated.
Implements
Examples
In the following example, the non-animated values of animated properties are retrieved and displayed.
