Form::OnClosed Method (EventArgs^)
Raises the Closed event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Caution |
|---|
The OnClosed method is obsolete in the .NET Framework version 2.0; use the OnFormClosed method instead. |
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnFormClosed method also allows derived classes to handle the event without attaching a delegate. Overriding this method is the preferred technique for handling the event in a derived class.
Caution |
|---|
The OnClosed and OnClosing methods are not called when the Application::Exit method is called to exit your application. If you have validation code in either of these methods that must be executed, you should call the Form::Close method for each open form individually before calling the Exit method. |
Notes to Implementers:
When overriding OnClosed in a derived class, be sure to call the base class's OnClosed method so that registered delegates receive the event.
The following code example demonstrates how to override the OnClosed method in a class derived from Form .
