Hi,

The OOTB 'ValidEmailAddress' validation rule will validate only the format " xxx@xxx "

We need to perform customization based on business requirement. I have tried the below customization at my end,

Create a EditValidate rule with the below code,

if (theValue == null || theValue.trim().equals("")) return false;
try {
            javax.mail.internet.InternetAddress emailAddr = new javax.mail.internet.InternetAddress(theValue);
            emailAddr.validate();
 }
catch (javax.mail.internet.AddressException ex){
   return false;
}
if(theValue.contains("."))
    return true; 
theProperty.addMessage("Enter a Valid Email Address");
return false;

For client side validation, use 'Post Value' for on-change event of the property outside the grid or add the below script in UserWorkForm,

<script>
var ruleEditValidate_validEmail = new validation_ValidationType("validMail", ruleEditValidate_isValidEmail);
    ruleEditValidate_validEmail.addEventFunction("onchange", ruleEditValidate_isValidEmail);
  function ruleEditValidate_isValidEmail(object) {

var x = pega.control.PlaceHolder.getValue(object);

    if (null == x || "" == x) {
        return;
    }

    // Regular expression for email address
    // RFC822 regular expression

    var emailReg = /^\w+@[a-zA-Z_]+?\.[a-zA-Z]+$/;

    var validMail = emailReg.test(x);

    if (!validMail) {
        return display_getValidationError(object, ruleEditValidate_isValidEmailAddressMsgStr, "", true);
    }
}
  </script>

Note: ValidMail (Mentioned in above script) is the custom edit validate rule created.

When I use the above customization, it validates the email address and throws error if the entered value is not in the format " Proprietary information hidden "

Hope it helps!

Thanks,

Geeda.
