Raises the ValueChanged routed event.

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

protected virtual void OnValueChanged(
	double oldValue,
	double newValue
)

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.

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