                    required: true,
                    email: true                    
                },
                Password: {
                    required: true,
                    remote: {
                        url: "/Users/Login",
                        type: "Post",
                        data: {
                            Email: function () { return $("#Email").val(); },
                            Password:function(){return $("#Password").val();}
                        }
                    }
                   
                },
                remember: {
                    required: false
                }
            },
