PrintPreviewDialog::OnClosing Method (CancelEventArgs^)

 

This API supports the product infrastructure and is not intended to be used directly from your code.

Raises the Closing event.

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

protected:
virtual void OnClosing(
	CancelEventArgs^ e
) override

Parameters

e
Type: System.ComponentModel::CancelEventArgs^

Provides data for a cancelable event.

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 in a derived class, be sure to call the base class’s OnClosing method so that registered delegates receive the event.
