validate(silent?: boolean, validateValue?: string | string[]): boolean;
Parameters:
silent: boolean

- optional, the id(s) of the item(s) from data collection that should be validated. If not specified, the method validates the currently selected item(s).

, if a control is valid; otherwise, false

Example
// the method validates the specified value
form.getItem("combo").validate(true, "id_2"); // -> true/false
// the method validates the currently selected items
form.getItem("combo").validate(true); // -> true/false
When calling without parameters or setting the silent parameter to false, the method invokes the BeforeValidate and AfterValidate events and visually modifies the control.
// the method validates the specified item
form.getItem("combo").validate(false, "id_2"); // -> true/false
// the method validates the currently selected item(s)
form.getItem("combo").validate(); // -> true/false
