Pass a value from one controller to another in asp.net mvc

I've been new to ASP.NET MVC. This is what I'm doing. I've 2 Controllers:Home and Customerservice. Now I have a Customer list where when I click details gets redirected to the products he acquired. So, I need to pass in the id so that the products of that customer can be displayed. So, my home consists of customer details. Now i need to pass that id to CustomerService controller ,Index action. This is what I've done in Home:

  public ActionResult Customers()
    {
        var dc = new ServicesDataContext();
        var query = (from m in dc.Customers
                     select m);


        return View(query);
    }

    public ActionResult Details(int id)
    {
        var datacontext = new ServicesDataContext();
        var serviceToUpdate = datacontext.Customers.First(m => m.CustomerId == id);


        ViewData.Model = serviceToUpdate;
       // return View();
        return Redirect("/CustomerService");

    }
    [HttpPost]
    public ActionResult Details(FormCollection form)
    {
        var id = Int32.Parse(form[开发者_运维问答"CustomerID"]);
        var datacontext = new ServicesDataContext();
        var service = datacontext.Customers.First(m => m.CustomerId == id);
        return Redirect("Customers");

    }
}

Now I'm not sure whether I need to pass an id as parameter for index in CustomerService. SO can you please guide me in finishing this?

If you are using any Redirect (such as RedirectToAction) you can use TempData to store any parameters. The semantics have slightly changed in MVC 3 but TempData is designed to pass data between actions in a POST-Redirect-GET scenario.

Passing it as a parameter is probably your best option. Try using something like return RedirectToAction(ActionName, ControllerName, RouteValues);.
