Parameters

e

A DataGridViewAutoSizeColumnsModeEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

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