Hi Basha,

You can validate the email address using javascript

Inside script tag
function validateEmail(emailField){
        var reg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;

        if (reg.test(emailField.value) == false)
        {
            alert('Invalid Email Address');
            return false;
        }

        return true;

}

Hi, you can validate email address by using regular expression as below
"username" runat="server">
"RegularExpressionValidator1" runat="server"ControlToValidate="username"
ErrorMessage="Please enter valid email" ForeColor="Red"ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*">
