Scenarios: When to Validation

1. On Submit Validation:
   A set of form inputs can be validated when the form is submitted. If the validation for a form has been initiated, this will occur automatically. Example.
2. On Change Validation:
   Each form input can be validated when the input fires a change event - i.e. after typing something or selecting a value. This also occurs automatically as long as the validation has been initiated for the form or a set of controls. Example.
3. Custom Validation Scenarios:
   In addition to the above two built-in scenarios, a custom call can be made only for a set of inputs. This can occur from a custom trigger - as an example when a button is clicked. Example.
