Fehler, während die Daten an die Steuerung aus Sicht vorbei

Question

Dies ist mein Controller-Aktion Methode

[HttpPost] 
     public ActionResult UpdateOrder(List<State> objState) 
     { 
      DataTable dst_state = new DataTable(); 
      dst_state.Columns.Add("state_id", typeof(int)); 
      dst_state.Columns.Add("state_order_by", typeof(int)); 
      foreach (var abc in objState) 
      { 
       DataRow dr = dst_state.NewRow(); 
       dr["state_id"] = abc.state_id; 
       dr["state_order_by"] = abc.state_order; 
       dst_state.Rows.Add(dr); 
      } 
      State.UpdateOrderState(dst_state); 
      TempData["message"] = "Order Updated Successfully"; 
      return View("ViewState"); 
     } 

dies ist meiner Ansicht

Während aus Sicht der Datenweitergabe an die Steuerung der Reihenfolge Spalte zu aktualisieren, ich bin Nullenliste im Controller erhalten. Wie man die zwei Felder in der Steuerung liest, um die Reihenfolge zu aktualisieren. Bitte helfen Sie.

Answer 1

Ihre Parameter für Regler ist nicht Ihr Modell, sollte es sein:

public ActionResult UpdateOrder(dsmanager.Models.State model) 

dann innerhalb der Aktion Eigenschaften mit

zugreifen können

model.state_country_id
