System.Web.UI.WebControls Namespace   CheckBox Class

Occurs when the value of the Checked property changes between posts to the server.

[ VB ]
Public Event CheckedChanged As EventHandler

[ C# ]
public event EventHandler CheckedChanged;

[ C++ ]
public: __event EventHandler* CheckedChanged;

In [ JScript ], you can handle the events defined by a class, but you cannot define your own.

The method assigned to handle the event is passed an EventArgs object containing data related to the CheckedChanged event.

The CheckedChanged event is raised whenever the value of the Checked property changes between posts to the server.

This event does not post the page back to the server unless the AutoPostBack property is set to true. Also, the control must have viewstate enabled for the CheckedChanged event to work correctly.

For more information about handling events, see Web Forms Events Model.

The following examples demonstrate how to specify and code a handler for the CheckedChanged event of a CheckBox control.
