The FormClosed event occurs after a form is closed, either by the user, through the user interface (UI), or programmatically, through calls to methods such as Close in the Form class, or Exit in the Application class. If a form has any child or owned forms, a FormClosed event is also raised for each one.

The FormClosedEventArgs class provides data for the FormClosed event. The CloseReason property provides the reason why the form is being closed.
