-/**
- * TCheckBox class
- *
- * 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.
