If the validation fails, the action handler can choose how to proceed.For “submit” type buttons, that typically means showing error messages next to the relevant form fields.

Use error Class, error Element, wrapper, error Label Container, error Container, show Errors, success, error Placement, highlight, unhighlight, and ignore Title to control how invalid elements and error messages are displayed.does not automatically invoke validators on every form submit.This is actually a good thing, because it makes it much easier to decide when validation makes sense (e.g. We have already seen the most common pattern for invoking validation in our handler for the “order” button: call, but before the possible premature return in case of validation errors.focus Invalid focuses elements when submitting an invalid form.Use the debug option to ease setting up validation rules, it always prevents the default submit, even when script errors occur.This is no problem if the interface exists only for the form, but could be a problem if it is used in other contexts as well.Second, if we want to re-use a validator for multiple forms, we would need to modify multiple schemata.One, remove the "control Box" from the form, so the user cant close it that way. in the btn Cancel_Click event: Removehandeler Text Box1.validating, Addressof Text Box1_Validating -- Terry "Darin" wrote: I know that, but the problem is when the user clicks EXIT, the textbox.validating event is called BEFORE the cancel.click is done, so the textbox is being validated.
