Class \Prado\Web\UI\ActiveControls\TActiveRadioButton
The active control counter part to radio button. The \Prado\Web\UI\ActiveControls\setAutoPostBack property is set to true by default. Thus, when the radio button is clicked a \Prado\Web\UI\ActiveControls\onCallback event is raise after OnCheckedChanged event.
The \Prado\Web\UI\ActiveControls\setText and \Prado\Web\UI\ActiveControls\setChecked properties can be changed during a callback.
The \Prado\Web\UI\ActiveControls\setGroupName property may NOT be changed during callback because the client-side name attribute is read-only and can not be changed using javascript.
