Hi all,

if you want to change client side the mandatory status of a field, you can use these two functions:

//eg. addValidator("customerid", "Customer")
function addValidator(fieldName, fieldLabel) {


    if (typeof (Page_Validators) == 'undefined') return;
    // Create new validator
    $("#" + fieldName + "_label").parent().addClass("required");

    var newValidator = document.createElement('span');
    newValidator.style.display = "none";
    newValidator.id = "RequiredFieldValidator" + fieldName;
    newValidator.controltovalidate = "casetypecode";
    newValidator.errormessage = "<a href='#" + fieldName + "_label'>" + fieldLabel + " is a mandatory field.</a>";
    newValidator.validationGroup = "";
    newValidator.initialvalue = "";
    newValidator.evaluationfunction = function () {
        var value = $("#" + fieldName).val();
        if (value == null || value == "") {
            return false;
        } else {
            return true;
        }
    };

    // Add the new validator to the page validators array:
    Page_Validators.push(newValidator);

    // Wire-up the click event handler of the validation summary link
    $("a[href='#" + fieldName + "_label']").on("click", function () { scrollToAndFocus(fieldName + '_label', fieldName); });
}

//eg. removeValidator("customerid")
function removeValidator(fieldName) {
    $.each(Page_Validators, function (index, validator) {
        if (validator.id == "RequiredFieldValidator" + fieldName) {
            Page_Validators.splice(index, 1);
        }
   });

    $("#" + fieldName + "_label").parent().removeClass("required");
}

This code works only if the field was not previously mandatory on the CRM. I suggest you to use this code in order to manage mandatory fields directly client side.

Hope this helps.

RE: [HOW TO] Enable/Disable mandatory fields on portal form

You need discover how to properly check data presence in JavaScript.

So instead of just checking

$("#"+fieldname).val()

you need to look for more specific way to get value, like:

$("#"+fieldname").find("input[checked]").attr("value")

which return you value of checked radio button, or slightly change the condition to see if you have at least one checked radio.

That's true. But if you want to set a field mandatory under specific conditions you need to write client side code.

Hi,

You don't need to write code to make the field mandatory on Portals, You can simply add the metadata configuration for the attribute and select the field mandatory.

refer this blog: nishantrana.me/.../using-entity-form-metadata-to-configure-the-entity-form-in-portal-in-dynamics-365

Hope this helps.

RE: [HOW TO] Enable/Disable mandatory fields on portal form

I have added this code in the web form step. But for some reason it is not working.

The form is posting back to server and only server side fields are showing as mandatory.

Any idea on this. Is there any configurations required.
