PHP Класс Prado\Web\UI\WebControls\TCheckBox

TCheckBox displays a check box on the page. You can specify the caption to display beside the check box by setting the {@link setText Text} property. The caption can appear either on the right or left of the check box, which is determined by the {@link setTextAlign TextAlign} property. To determine whether the TCheckBox component is checked, test the {@link getChecked Checked} property. The {@link onCheckedChanged OnCheckedChanged} event is raised when the {@link getChecked Checked} state of the TCheckBox component changes between posts to the server. You can provide an event handler for the {@link onCheckedChanged OnCheckedChanged} event to to programmatically control the actions performed when the state of the TCheckBox component changes between posts to the server. If {@link setAutoPostBack AutoPostBack} is set true, changing the check box state will cause postback action. And if {@link setCausesValidation CausesValidation} is true, validation will also be processed, which can be further restricted within a {@link setValidationGroup ValidationGroup}. Note, {@link setText Text} is rendered as is. Make sure it does not contain unwanted characters that may bring security vulnerabilities. Показать файл Открыть проект Примеры использования класса
