Occurs when the form is closing.
[Visual Basic]
Public Event Closing As CancelEventHandler
[C#]
public event CancelEventHandler Closing;
[C++]
public: __event CancelEventHandler* Closing;
[JScript] In JScript, you can handle the events defined by a class, but you
cannot define your own.
Event Data
The event handler receives an argument of type CancelEventArgs containing
data related to this event. The following CancelEventArgs property provides
information specific to this event.
Property Description
Cancel Gets or sets a value indicating whether the event should be
canceled.
Remarks
The Closing event occurs as the form is being closed. When a form is closed,
all resources created within the object are released and the form is
disposed. If you cancel this event, the form remains opened. To cancel the
closure of a form, set the Cancel property of the CancelEventArgs passed to
your event handler to true.
When a form is displayed as a modal dialog box, clicking the Close button
(the button with an X at the upper-right corner of the form) causes the form
to be hidden and the DialogResult property to be set to DialogResult.Cancel.
You can override the value assigned to the DialogResult property when the
user clicks the Close button by setting the DialogResult property in an
event handler for the Closing event of the form.
Note When the Close method is called on a Form displayed as a modeless
window, you cannot call the Show method to make the form visible, because
the form's resources have already been released. To hide a form and then
make it visible, use the Control.Hide method.
CAUTION The Form.Closed and Form.Closing events are not raised when the
Application.Exit method is called to exit your application. If you have
validation code in either of these events that must be executed, you should
call the Form.Close method for each open form individually before calling
the Exit method.
If the form is an MDI parent form, the Closing events of all MDI child forms
are raised before the MDI parent form's Closing event is raised. In
addition, the Closed events of all MDI child forms are raised before the
Closed event of the MDI parent form is raised. Canceling the Closing event
of an MDI child form does not prevent the Closing event of the MDI parent
form from being raised. However, cancelling the event will set to false the
System.Windows.Forms.ClosingEventArgs.Cancel property of the
System.Windows.Forms.ClosingEventArgs that is passed as a parameter to the
parent form. To force all MDI parent and child forms to close, set the
System.Windows.Forms.ClosingEventArgs.Cancel property to false in the MDI
parent form.

Public Event Closed As EventHandler
[C#]
public event EventHandler Closed;
[C++]
public: __event EventHandler* Closed;
[JScript] In JScript, you can handle the events defined by a class, but you
cannot define your own.
Event Data
The event handler receives an argument of type EventArgs.
Remarks
This event occurs after the form has been closed by the user or by the Close
method of the form. To prevent a form from closing, handle the Closing event
and set the Cancel property of the CancelEventArgs passed to your
event-handling method to true.
You can use this event to perform tasks such as freeing resources used by
the form and to save information entered in the form or to update its parent
form.
CAUTION The Form.Closed and Form.Closing events are not raised when the
Application.Exit method is called to exit your application. If you have
validation code in either of these events that must be executed, you should
call the Form.Close method for each open form individually before calling
the Exit method.
If the form is an MDI parent form, the Closing events of all MDI child forms
are raised before the MDI parent form's Closing event is raised. In
addition, the Closed events of all MDI child forms are raised before the
Closed event of the MDI parent form is raised.
