我有MVC 4項目,應該爲投標創建一組記錄,然後保存它應該重定向到某個頁面,我將顯示所有記錄。查看不顯示數據傳遞的數據

下面是我保存後的問題,它會重定向,但從模型傳遞到視圖的數據不會更新/不顯示​​在視圖上。

這裏是我的控制器動作中獲取數據:

private CoverageViewModel coveragedata = new CoverageViewModel(); 
    private NewProposalDBContext db = new NewProposalDBContext(); 
    // 
    // GET: /Coverage/ 
    public ActionResult Index() 
    { 
     CoverageViewModel coverage = new CoverageViewModel(); 
     List<Institution> institutions = db.Institutions.ToList(); 

     if (coveragedata.Proposal != null) 
     { 
      coverage.Institution = institutions; 
      coverage.Proposal = (List<NewProposal>)Session["coveragedata"]; 
     } 
     else 
     { 
      List<NewProposal> listProposal = new List<NewProposal>(); 
      listProposal = db.NewProposal.ToList(); 
      List<LeadsManagement> listLeadsMgt = new List<LeadsManagement>(); 
      listLeadsMgt = db.LeadsManagements.ToList(); 
      List<LeadEmployees> listLeadsEmployees = new List<LeadEmployees>(); 
      listLeadsEmployees = db.LeadEmployees.ToList(); 
      List<VacsInAction> listVacsInAction = new List<VacsInAction>(); 
      listVacsInAction = db.VacsInActions.ToList(); 
      List<NewProposal> listofImplementedProposal = new List<NewProposal>(); 
      listofImplementedProposal = 
         db.NewProposal.Where(x => x.Status.StatusID == 3).ToList(); 

      coverage.Institution = institutions; 
      coverage.Proposal = listProposal; 
      coverage.LeadsManagement = listLeadsMgt; 
      coverage.LeadsEmployee = listLeadsEmployees; 
      coverage.VacsInAction = listVacsInAction; 
    } 

    return View(coverage); 
} 

這裏是我查看 我使用的會話只是爲了讓來自控制器的最新數據,並嘗試覆蓋模式的值。

@{ 
ViewBag.Title = "Index"; 

if(Session["coveragedata"] != null) 
{ 
    Model.Proposal = (List<ULIV.ViewModels.NewProposal>)Session["coveragedata"]; 
} 

if(Session["leadsMgt"] != null) 
{ 
    Model.LeadsManagement = (List<ULIV.Models.LeadsManagement>)Session["leadsMgt"]; 
} 

if(Session["leadsEmp"] != null) 
{ 
    Model.LeadsEmployee = (List<ULIV.Models.LeadEmployees>)Session["leadsEmp"]; 
} 

這裏的顯示數據的實際:

@foreach (var proposal in Model.Proposal) 
{ 
     if (proposal.Status.StatusID == 1) 
     { 
      <tr> 
      <td align="center"> 
        @Html.DisplayFor(modelItem => proposal.ProposalCode) 
      </td> 
      <td align="center"> 
        @Html.DisplayFor(modelItem => proposal.VaccineType.VaccineTypeName) 
      </td> 
      <td align="center"> 
        @Html.DisplayFor(modelItem => proposal.Product.ProductName) 
      </td> 
      <td align="center"> 
        @Html.DisplayFor(modelItem => proposal.ProposedUnitPrice) 
      </td> 
      <td align="center"> 
        @Html.DisplayFor(modelItem => proposal.ProposedVolume) 
      </td> 
      <td align="center"> 
        @Html.DisplayFor(modelItem => proposal.Status.StatusName) 
      </td> 
      </tr> 
     } 
}

你爲什麼要使用會話?如果您正在重定向,只需創建一個包含新視圖更新數據的模型,並使用模型顯示 –

「if(coveragedata.Proposal!= null)」的含義是什麼? - 它總是**爲空(您每次調用方法時,都會初始化一個新的覆蓋實例!)。並停止使用會話! –

我覺得你的觀點是不強類型視圖。您應該在頁面頂部添加一行 ,如

@model CoverageViewModel。

我有上面我沒有發佈在這裏 –

我想這可能工作:

你已經循環模型列表,以便您可以使用此:

@Html.Display(proposal.ProposalCode)

,而不是這樣的:

@Html.DisplayFor(modelItem => proposal.ProposalCode)
