ApplicationSettingsBase::OnSettingChanging Method (Object^, SettingChangingEventArgs^)


Raises the SettingChanging event.

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

virtual void OnSettingChanging(
	Object^ sender,
	SettingChangingEventArgs^ e


Type: System::Object^

The source of the event.

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.
