Asp.Net Validation Summary: How to show ValidationSummary using JavaScript

ValidationSummaryOnSubmit(); function exposed at client side.

<script type="text/javascript" language="javascript">

function PerformValidation() {
              ValidatorValidate(document.getElementById('rfvName'));
              ValidationSummaryOnSubmit();
 }

</script>

 

Note:  ValidationSummaryOnSubmit takes an argument as validationGroup. If you want to show ValidationSummary for a particular validation group, then call function passing name of validation group.

If function is called without any arguments, then it will show all ValidationSummary (if error) in page.
