See also: Form is valid
Triggering event – Abstract
This is triggered when the validation of the form was unsuccessful.
â–ºNOTEâ—„ This event is triggered for each failed validation, not only if the form was previously valid!
Tip: The triggering event Changed could be combined with the Validate element behavior to ensure a complete triggering of the 'Form is invalid' event.
However, this is not recommended for extremely large forms, because the validation of the form is triggered by every change, no matter how small. However, a larger delayed execution of the validation could be useful here.
