Wie Parameter von Teilansicht an Controller-Klasse in Mvc übergeben werden 4

Question

Ich möchte Redirect Details eines bestimmten Elements nach dem Klick auf ist Name auf der Homepage. Wie kann ich das machen?

Dies ist home controller meines Projekts:

namespace WEB1.Controllers 
{ 
    public class HomeController : Controller 
    { 

     private projectDBEntities db = new projectDBEntities(); 

     public ActionResult Index() 
     { 
      return View(); 
     } 

     public ActionResult topPlace() 
     { 
      var top_place = db.Places.OrderByDescending(a => a.place_rate).Take(6).ToList(); 
      return PartialView("_topPlace", top_place); 
     } 

     public ActionResult topServices() 
     { 
      var top_service = db.service_provider.OrderByDescending(a => a.Sp_rate).Take(6).ToList(); 
      return PartialView("_topService",top_service); 
     } 


    } 
} 

Dies ist TDS controller:

namespace WEB1.Controllers 
{ 
    public class TDSController : Controller 
    { 
     private projectDBEntities db = new projectDBEntities(); 

     public ActionResult Details(int id = 0) 
     { 
      Place place = db.Places.Find(id); 
      if (place == null) 
      { 
       return HttpNotFound(); 
      } 
      return View(place); 
     } 



     public ActionResult Index(int? page) 
     { 
      var places = db.Places.Include(p => p.city).OrderByDescending(s => s.place_rate); 
      if(Request.HttpMethod != "GET") 
      { 
       page = 1; 
      } 
      int pageSize = 5; 
      int pageNumber =(page ?? 1); 
      return View(places.ToPagedList(pageNumber, pageSize)); 
     } 

     public ActionResult Historical(int? page) 
     { 
      var places = db.Places.Include(p => p.city).OrderByDescending(s => s.place_rate).Where(s => s.Place_type == "Historical"); 
      if (Request.HttpMethod != "GET") 
      { 
       page = 1; 
      } 
      int pageSize = 5; 
      int pageNumber = (page ?? 1); 
      return View(places.ToPagedList(pageNumber, pageSize)); 
     } 


     public ActionResult Religious(int? page) 
     { 
      var places = db.Places.Include(p => p.city).OrderByDescending(s => s.place_rate).Where(s => s.Place_type == "Religious"); 
      if (Request.HttpMethod != "GET") 
      { 
       page = 1; 
      } 
      int pageSize = 5; 
      int pageNumber = (page ?? 1); 
      return View(places.ToPagedList(pageNumber, pageSize)); 
     } 

     public ActionResult Scenic(int? page) 
     { 
      var places = db.Places.Include(p => p.city).OrderByDescending(s => s.place_rate).Where(s => s.Place_type == "Scenic"); 
      if (Request.HttpMethod != "GET") 
      { 
       page = 1; 
      } 
      int pageSize = 5; 
      int pageNumber = (page ?? 1); 
      return View(places.ToPagedList(pageNumber, pageSize)); 
     } 


     public ActionResult Educational(int? page) 
     { 
      var places = db.Places.Include(p => p.city).OrderByDescending(s => s.place_rate).Where(s => s.Place_type == "Educational"); 
      if (Request.HttpMethod != "GET") 
      { 
       page = 1; 
      } 
      int pageSize = 5; 
      int pageNumber = (page ?? 1); 
      return View(places.ToPagedList(pageNumber, pageSize)); 
     } 


     protected override void Dispose(bool disposing) 
     { 
      db.Dispose(); 
      base.Dispose(disposing); 
     } 
    } 
} 

Dies ist top places partail view:

@model IEnumerable<WEB1.Models.Place> 
<div class="homebody"> 

    <h3>Most Populer Places</h3> 
    @foreach (var item in Model) 
    { 
     <div class="span4"> 
      <div class="item1"> 
       <p class="name">@Html.ActionLink(item.Place_name, "Details", "TDS", new { id = item.PID })</p> 
       <p class="cattype">@Html.DisplayFor(modelItem => item.Place_location)</p> 
       <p>@Html.DisplayFor(modelItem => item.city.Cityname)</p> 
       <p>@Html.DisplayFor(modelItem => item.place_rate)</p> 
      </div> 
     </div> 
    } 
</div> 

Answer 1

Sie verwenden von

@Html.ActionLink(item.Place_name, "Details", "TDS", new { id = item.PID }) 

verwendet this overload und Hinzufügen der item.PID als htmlAttribute, kein Routenwert. Sie müssen this overload verwenden, so dass Sie Code

@Html.ActionLink(item.Place_name, "Details", "TDS", new { id = item.PID }, null)
