DockItem.OnClosing Method

protected virtual void OnClosing(
	CancelEventArgs e
)

Protected Overridable Sub OnClosing ( 
	e As CancelEventArgs
)

Parameters

e

Type: System.ComponentModelCancelEventArgs
An CancelEventArgs that contains the event data.

This method allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

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