By default, a validation summary will collect * {@link TBaseValidator::getErrorMessage ErrorMessage} of all failed validators * on the page. If {@link getValidationGroup ValidationGroup} is not * empty, only those validators who belong to the group will show their error messages * in the summary. * * The summary can be displayed as a list, as a bulleted list, or as a single * paragraph based on the {@link setDisplayMode DisplayMode} property. * The messages shown can be prefixed with {@link setHeaderText HeaderText}. * * The summary can be displayed on the Web page and in a message box by setting * the {@link setShowSummary ShowSummary} and {@link setShowMessageBox ShowMessageBox} * properties, respectively. Note, the latter is only effective when * {@link setEnableClientScript EnableClientScript} is true. * * @author Qiang Xue <qiang.xue@gmail.com> * @version $Id$ * @package System.Web.UI.WebControls * @since 3.0 */ class TValidationSummary extends TWebControl { /** * @var TValidatorClientScript validator client-script options. */ private $_clientScript; /** * Constructor. * This method sets the foreground color to red. */ public function __construct() { parent::__construct(); $this->setForeColor('red'); } /** * @return TValidationSummaryDisplayStyle the style of displaying the error messages.
