protected virtual void OnAutoSizeColumnModeChanged (System.Windows.Forms.DataGridViewAutoSizeColumnModeEventArgs e);

abstract member OnAutoSizeColumnModeChanged : System.Windows.Forms.DataGridViewAutoSizeColumnModeEventArgs -> unit
override this.OnAutoSizeColumnModeChanged : System.Windows.Forms.DataGridViewAutoSizeColumnModeEventArgs -> unit

Protected Overridable Sub OnAutoSizeColumnModeChanged (e As DataGridViewAutoSizeColumnModeEventArgs)

Parameters

e: DataGridViewAutoSizeColumnModeEventArgs

A DataGridViewAutoSizeColumnModeEventArgs that contains the event data.

Exceptions

InvalidOperationException

The value of the Column property of e is null.

Remarks

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

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