ID value not passed to different action method

Question

In my project, there are two controllers namely Home controller and Hotel controller.I have used view model to combine two model classes.Bellow I have Add my controllers.

Home Controller

public ActionResult Index(){
        List<ImageData> details = new List<ImageData>();

        var sp_details = (from s in db.service_provider
                          join p in db.pictures on s.SPID equals p.SPID
                          join c in db.cities on s.City_ID equals c.City_ID
                          select new { s.SPID, s.Sp_name, s.Sp_rate, s.service_type, c.Cityname, p.pic }).OrderByDescending(s => s.Sp_rate).Where(p => p.service_type == "Restaurant").Take(3).ToList();

        foreach (var item in sp_details)
        {
            ImageData SpView = new ImageData(); // ViewModel
            SpView.SPID = item.SPID;
            SpView.Sp_name = item.Sp_name;
            SpView.Cityname = item.Cityname;
            SpView.Sp_rate = item.Sp_rate;
            SpView.pic = item.pic;

            details.Add(SpView);
        }
        return View(details);
    }

Hotel controller

public ActionResult Details(int id = 0)
    {
        List<ImageData> details = new List<ImageData>();

        var sp_details = (from s in db.service_provider
                          join p in db.pictures on s.SPID equals p.SPID
                          join c in db.cities on s.City_ID equals c.City_ID
                          where s.SPID == id
                          select new ImageData()
                          {
                              Sp_name = s.Sp_name,
                              Sp_location = s.Sp_location,
                              Cityname = c.Cityname,
                              service_type = s.service_type,
                              Sp_description = s.Sp_description,
                              Sp_rate = s.Sp_rate,
                              Sp_web = s.Sp_web,
                              Cnt_wh = s.Cnt_wh,
                              pic = p.pic
                          });



        if (details == null)
        {
            return HttpNotFound();
        }

        return View(sp_details);
    }

below is part of Index view.I have passed id value to Details action method in Hotel Controller.

 <p class="name">@Html.ActionLink(item.Sp_name, "Details","Hotel", new { id = item.SPID })</p>

but value not passed and not display details of Details Action method in Hotel Controller.Since I'm new to mvc 4 I couldn't able to find the mistake.

Try explicitly including an additional null parameter that would represent your htmlAttributes parameter and would match this overload to ensure that your object was properly passed along as route parameters :

@Html.ActionLink(item.Sp_name, "Details","Hotel", new { id = item.SPID }, null)

The ActionLink() helper doesn't contain an overload that only accepts the Text, Action, Controller and RouteValues, which you have supplied, so this extra parameter is necessary.
