Raises the SettingChanging event.
protected:
virtual void OnSettingChanging(System::Object ^ sender, System::Configuration::SettingChangingEventArgs ^ e);
protected virtual void OnSettingChanging (object sender, System.Configuration.SettingChangingEventArgs e);
abstract member OnSettingChanging : obj * System.Configuration.SettingChangingEventArgs -> unit
override this.OnSettingChanging : obj * System.Configuration.SettingChangingEventArgs -> unit
Protected Overridable Sub OnSettingChanging (sender As Object, e As SettingChangingEventArgs)
Parameters
- sender
- Object
The source of the event.
A SettingChangingEventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
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(Object, SettingChangingEventArgs) in a derived class, be sure to call the base class's OnSettingChanging(Object, SettingChangingEventArgs) method so that registered delegates receive the event.
