Question

the problem is that i am not able to recieve any value in the controller . what could be wrong? the code is here.

  $('#save').click(function () {

        var UserLoginViewModel = { UserName: $('vcr_UserName').val(),
            Password: $('vcr_Password').val()
        };
        $.ajax({
            url: "/User/Login",
            data: JSON.stringify(UserLoginViewModel),
            contenttype: "application/json; charset=utf-8",
            success: function (mydata) {
                $("#message").html("Login");
            },
            error: function () {
                $("#message").html("error");
            },
            type: "POST",
            datatype: "json"
        });
        return false;
    });
});

    [HttpPost]
    public ActionResult Login(UserLoginViewModel UserLoginViewModel)
    {

    }

You’re going to need an action filter or similar to intercept the json from the post body.

Here’s a starter

Provider Factory

but here is the article that sorted this for me On Haacked

It is good if you know the type you are deserialising into up front, but if you need polymorphism you’ll end up using these ideas in an action filter.
