Form component supports flexible validation triggers, allowing validation on value updates, blur events, form mount, or submission. These behaviors can be configured at form level or on specific fields via the
|
|
<i>validateOnValueUpdate</i>, <i>validateOnBlur</i>, <i>validateOnMount</i>, and <i>validateOnSubmit</i> options of the <i>formControl</i> property.
|
|
</p>
|
|
<p>In this example, form disables <i>validateOnValueUpdate</i> and enables <i>validateOnBlur</i> at form level, and validates <b>firstName</b> on mount. The <i>firstName</i> field, overrides the form level setting locally.</p>
