Using MVC it should be rather straight forward as the framework is designed to to turn a form into a model.

[HttpGet]
public ActionResult Edit(int id)
{
    // (you can probably rewrite this using a lambda
    var orderWithLines = from o in db.Orders.Include("OrderLines")
                         select o;

    // Use ViewData rather than passing in the object in the View() method.
    ViewData.Model = orderWithLines.FirstOrDefault(x => x.ID = id);
    return View();
}

[HttpPost]
public ActionResult Edit(OrderTracker.Models.Order model)
{
    if (ModelState.IsValid)
    {
        // call the service layer / repository / db to persist the object graph
        _service.Save(model); // this assumes your view models are the same as your domain
    }
}
