FormClosingEventHandler Delegate

Represents the method that handles a FormClosing event.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in

public delegate void FormClosingEventHandler (
	Object sender,
	FormClosingEventArgs e
/** @delegate */
public delegate void FormClosingEventHandler (
	Object sender, 
	FormClosingEventArgs e
Not applicable.



The source of the event.


A FormClosingEventArgs that contains the event data.

The FormClosing event occurs just before 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. This event can be canceled.

When you create a FormClosingEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.
