 protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
    {
        if (Membership.ValidateUser(Login1.UserName, Login1.Password) == true)
        {
            Login1.Visible = true;
            Session["user"] = User.Identity.Name;

            var userRoles = Roles.GetRolesForUser(Login1.UserName);
            var userIdentity = new GenericIdentity(Login1.UserName);
            var principal = new GenericPrincipal(userIdentity, userRoles);

            Context.User = principal;

            if (User.IsInRole("Admin"))
                Response.Redirect("~/ThePageForAdmin");

            if (User.IsInRole("User"))
                Response.Redirect("~/ThePageForUser");

            if (User.IsInRole("Customer"))
                Response.Redirect("~/ThePageForCustomer");
        }
        else
        {

            Response.Write("Invalid Login");
        }
    }
