Hi,

use this javascript

C#

function checkEmail() {

    var email = document.getElementById('txtEmail');
    var emailFormat = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;

    if (!emailFormat.test(email.value)) {
    alert('Invalid Email');
    email.focus;
    return false;
 }

Good Luck
