System.Web.UI.WebControls Namespace   CheckBox Class

Sets or retrieves a value indicating whether the CheckBox control is checked.

This property accepts or returns only a boolean value: true to indicate a checked state; otherwise false. Default value is false.

Use the Checked property to declaratively set the initial state of a CheckBox control. This property can also be used to programmatically specify or determine whether the CheckBox control is checked.

In certain cases, as when checkboxes or radiobuttons ( which inherit this property ) are used within templated controls, the Checked property is usually obtained dynamically from a data source.

<asp:checkbox runat = "server" 
   checked=<%# ( ( IDataRecord ) Container.DataItem ) [ "Stopped" ] %> />

The following examples demonstrate using the Checked property at design time and at run time.
