ApplicationSettingsBase.OnSettingChanging Method (Object, SettingChangingEventArgs)

 

Raises the SettingChanging event.

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

protected virtual void OnSettingChanging(
	object sender,
	SettingChangingEventArgs e
)

Parameters

sender
Type: System.Object

The source of the event.

e
Type: System.Configuration.SettingChangingEventArgs

A SettingChangingEventArgs that contains the event data.

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