Control.OnEnabledChanged(EventArgs) Method

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Source:

Control.cs

Raises the EnabledChanged event.

C#

protected virtual void OnEnabledChanged(EventArgs e);

Parameters

e

EventArgs

An EventArgs that contains the event data.

Remarks

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

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