NumericUpDown.OnValueChanged Method

Raises the ValueChanged event.

[Visual Basic]
Protected Overridable Sub OnValueChanged( _
   ByVal e As EventArgs _
protected virtual void OnValueChanged(
 EventArgs e
protected: virtual void OnValueChanged(
 EventArgs* e
protected function OnValueChanged(
   e : EventArgs


An EventArgs that contains the event data.


Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnValueChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors:  When overriding OnValueChanged in a derived class, be sure to call the base class's OnValueChanged method so that registered delegates receive the event.
