Raises the ValueChanged routed event.

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


Protected Overridable Sub OnValueChanged ( _
    oldValue As Double, _
    newValue As Double _
protected virtual void OnValueChanged(
    double oldValue,
    double newValue



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.
