Raises the SettingChanging event.

Namespace: System.Configuration
Assembly: System (in system.dll)

protected virtual void OnSettingChanging (
	Object sender,
	SettingChangingEventArgs e
)
protected void OnSettingChanging (
	Object sender, 
	SettingChangingEventArgs e
)
protected function OnSettingChanging (
	sender : Object, 
	e : SettingChangingEventArgs
)
Not applicable.

Parameters

sender

The source of the event.

e

A SettingChangingEventArgs that contains the event data.

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

The OnSettingChanging 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 OnSettingChanging in a derived class, be sure to call the base class's OnSettingChanging method so that registered delegates receive the event.
