How to Determine if page is valid in JavaScript - ASP NET

Question

I am trying to check the validation of an user control that was opened using the JavaScript window.showModalDialog() and checking the 'Page.IsValid' property on the server side does not work. I am using ASP.NET validation controls for page validation.

What is the best way to determine if a form on an ASPX page is valid in JavaScript?

Hello @kartik,

 Make the call on an input submit. Hopefully this code sample will get you started!

    <input type="submit" value="Submit" onclick"ValidatePage();" />

    <script type="text/javascript">

    function ValidatePage() {

        if (typeof (Page_ClientValidate) == 'function') {
            Page_ClientValidate();
        }

        if (Page_IsValid) {
            // do something
            alert('Page is valid!');                
        }
        else {
            // do something else
            alert('Page is not valid!');
        }
    }

</script>

Hope it helps!!

Thank You!!
