PrintPreviewDialog.OnClosing(CancelEventArgs) Method

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Source:

PrintPreviewDialog.cs

Raises the Closing event.

C#

protected override void OnClosing(System.ComponentModel.CancelEventArgs e);

Parameters

e

CancelEventArgs

Provides data for a cancelable event.

Remarks

This method is not relevant for this class.

The OnClosing method invalidates the preview so it is regenerated when the dialog is reopened.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnClosing 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 OnClosing(CancelEventArgs) in a derived class, be sure to call the base class' OnClosing(CancelEventArgs) method so that registered delegates receive the event.
