Question

我在MVC 5中创建银行应用程序。

按银行加载表格，按银行加载表格行，

但我无法弄清楚这与上面的图像完全相同，

这就是我得到的，它有10个表，而只有2个表

这是上面视图的cshtml代码

    @model IEnumerable<albaraka.Models.ProductApprovals>

@{
    ViewBag.Title = "Product_Approvals";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>sadfasf</h2>
<h2>Product Approvals</h2>

    @using (Html.BeginForm("Index", "Student", FormMethod.Get))
    {


    <div> Filter by : Date @Html.TextBox("SearchString", ViewBag.CurrentFilter as string)         Filter by : Country @Html.TextBox("SearchString", ViewBag.CurrentFilter as string) <input type="submit" value="Search" /> </div>


    }


@foreach (var item in Model)
{


    @Html.DisplayNameFor(model => model.SubsidaryName);   <p &nbsp />    @Html.DisplayFor(modelItem => item.SubsidaryName);


    <table class="table">
        <tr>

            <th>
                @Html.DisplayNameFor(model => model.ProductNameEn)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.ProdcutNameAr)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.CurrentStatus)
            </th>
            <th>
                Actions
            </th>
        </tr>



        @foreach (var inside in Model)
        {

            if (inside.Subsidary_ID == item.Subsidary_ID)
            {

         <tr>

            <td>
                @Html.DisplayFor(modelItem => inside.ProductNameEn)
            </td>
            <td>
                @Html.DisplayFor(modelItem => inside.ProdcutNameAr)
            </td>
            <td>
                @Html.DisplayFor(modelItem => inside.CurrentStatus)
            </td>
            <td>
                @Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
                @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
                @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
            </td>
        </tr>
            }
        }
    </table>
}

这是Model类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace albaraka.Models
{
    public class ProductApprovals
    {

        public DateTime SearchDate { get; set; }
        public string Country { get; set; }
        public string Product_ID { get; set; }
        public string Subsidary_ID { get; set; }
        public string SubsidaryName { get; set; }
        public string ProductNameEn { get; set; }
        public string ProdcutNameAr { get; set; }
        public string CurrentStatus { get; set; }

    }
}

这是Controller类

 public ActionResult Product_Approvals()
{
    var productApproveResult =(from p in db.AB_Product
                              join s in db.AB_Subsidary on p.Subsidary_ID equals s.SubsidaryID
                              select new ProductApprovals
                              {
                                  Product_ID    = p.ProductID,
                                  Subsidary_ID  = s.SubsidaryID,
                                  SubsidaryName = s.SubsidaryNameEn,
                                  ProductNameEn = p.ProductTitleEn,
                                  ProdcutNameAr = p.ProductTitleAr,
                                  CurrentStatus = p.Status                                         

                              }).ToList();

    return View(productApproveResult);
}

如果可以在视图页面中显示这种方法，可以停止这种重复，appricate

您需要一个视图模型来表示要在视图中显示的内容。它应该像

public class BankVM
{
  public string SubsidaryName { get; set; }
  public IEnumerable<ProductVM> Products { get; set; }
}
public class ProductVM
{
  public string ProductNameEn { get; set; }
  public string ProdcutNameAr { get; set; }
  public string CurrentStatus { get; set; }
}

并将BankVM的集合传递给视图

@model IEnumerable<yourAssembly.BankVM>
@foreach(var bank in Model)
{
  <h3>@Html.DisplayFor(m => bank.SubsidaryName)</h3>
  <table>
    foreach(var product in bank.Products)
    {
      <tr>
        <td>@Html.DisplayFor(m => product.ProductNameEn)</td>
        <td>@Html.DisplayFor(m => product.ProductNameAr)</td>
        ....
      </tr>
    }
  </table>
}

在控制器中，您可以使用Linq .GroupBy()方法填充BankVM

的集合
