CheckBox.OnCheckStateChanged(EventArgs) Method

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Source:

CheckBox.cs

Raises the CheckStateChanged event.

C#

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