Toggle the ASP validation control using JavaScript

I am looking to control the validation of my form using JavaScript. When a user clicks on a radio button in a list (yes or no), 2-3 rows are displayed. If the user selects "Yes," they must enter input into a textbox in one of those rows. To enforce this, I have set up required field validators. On page load, all validators are disabled and are enabled via JavaScript with ValidatorEnable(control, enable) when needed. However, when a radio button is clicked, the rows become visible and an error message from the validation control appears simultaneously. I want the error message to only show when the submit button is clicked. How can I achieve this?

Answer №1

Insert the following code immediately after calling the ValidatorEnable(control, enable) method:

if (control.style.visibility == "visible") {
     control.style.visibility = "hidden";
} else {
     control.style.display = "none";
}

Answer №2

function CheckValidatorsOnPage() {
    var hasValidators = false;

    try {
        if (Page_Validators.length > 0) {
            hasValidators = true;
        }
    }
    catch (error) {
    }

    return hasValidators;
}

function ToggleValidationGroup(validationGroupName, isEnabled) {
    if (CheckValidatorsOnPage()) {
        for (i = 0; i < Page_Validators.length; i++) {
            if (Page_Validators[i].validationGroup == validationGroupName) {
                ValidatorEnable(Page_Validators[i], isEnabled);
            }
        }
    }
}

Then make the following call:

ToggleValidationGroup('validationgroup', false);

I believe this function will assist you...
