如何在mvc视图中显示组数据我的视图无法正常工作

Question

我有一个partial_view，我在那里传递了一个架构详细信息的数据表。 我也想要下面的显示视图 Schema_Details表：

SType : Equity
S_Name|Allocation|Lum_Sum_Value|SIP
 Xyz   |30%      |250000       |2000

在控制器中，我获得数据分组依据 我的控制器：

[HttpPost]
public Action Result recommended-portfolio(int sName)
 {
   using (var db = new WFTradeEntities())
    {

var tr = db.Schema_Details.ToList().Where(x => x.RID == sName).Select(x => new Schema_Details
   {
     SID = x.SID, RID = x.RID,Schema_Name = x.Schema_Name,SType = x.SType,
     InvestmentType = x.InvestmentType, Allocation = x.Allocation,
     Lum_Sum_Amount = x.Lum_Sum_Amount,
        cal = Convert.ToDouble(x.Allocatio/100.0 * 25000), 
      SIP=Convert.ToDouble(x.Allocation / 100.0 * 5000)}).GroupBy(x => x.SType);
   return PartialView("_PortfolioTable", tr);
        }
    }

我的视图不显示网格：

我的观看数据：  @model IEnumerable

   @foreach (var group in Model.GroupBy(item => item.SType)) 
    { 
         @Html.Encode(group.Key) 
         @foreach (var item in group) { 
         @Html.Encode(item.Schema_Name)
     }
