 void OnFreezablePropertyChanged(System::Windows::DependencyObject ^ oldValue, System::Windows::DependencyObject ^ newValue);
protected void OnFreezablePropertyChanged (System.Windows.DependencyObject oldValue, System.Windows.DependencyObject newValue);
member this.OnFreezablePropertyChanged : System.Windows.DependencyObject * System.Windows.DependencyObject -> unit
Protected Sub OnFreezablePropertyChanged (oldValue As DependencyObject, newValue As DependencyObject)

參數

oldValue
DependencyObject DependencyObject DependencyObject DependencyObject

資料成員先前的值。The previous value of the data member.

newValue
DependencyObject DependencyObject DependencyObject DependencyObject

資料成員目前的值。The current value of the data member.

備註

每當Freezable DependencyPropertyDependencyObject儲存為的資料成員設定時, 繼承者就應該呼叫這個方法。This method should be called by Freezable inheritors each time a DependencyObject data member that is not stored as a DependencyProperty is set.

DependencyObject 對於DependencyProperty使用儲存的資料成員, 不需要呼叫這個方法。This method does not need to be called for DependencyObject data members that are stored using a DependencyProperty.
