	newValue As Double _
)

Parameters

oldValue

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.
