RangeBase.OnValueChanged Method

Raises the ValueChanged routed event.

Namespace:  System.Windows.Controls.Primitives
Assembly:  PresentationFramework (in PresentationFramework.dll)

protected virtual void OnValueChanged(
	double oldValue,
	double newValue
)
You cannot use methods in XAML.

Parameters

oldValue
Type: System.Double

Old value of the Value property

newValue
Type: System.Double

New value of the Value property

Subclasses of the RangeBase can use this method to respond when the value property changes instead of overriding the FrameworkPropertyMetadata to provide a new PropertyChangedCallback function. For more information, see Dependency Property Callbacks and Validation.

The OnValueChanged method raises the ValueChanged event. When overriding OnValueChanged in a derived class, be sure to call the base class’s OnValueChanged method so that registered delegates receive the event.

Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003
