asp.net-mvc - Asp.net ModelView Approach

Question

I am trying to build a one-page application with asp.net MVC4(razor syntax) and databasefirst approach. You can see a simple mock-up of my application as below.

-OPPORTUNITY<br />
--OPPORTUNITY DETAIL(1)<br />
---Seleted Solution-1<br />
---Seleted Solution-2<br />
---Seleted Solution-3<br />
--OPPORTUNITY DETAIL(2)<br />
---Seleted Solution-1<br />
---Seleted Solution-2<br />
--OPPORTUNITY DETAIL(3)<br />
---Seleted Solution-1<br />
---Seleted Solution-2<br />
---Seleted Solution-3<br />

I have lots of Solutions in a table and there are lot of paramaters. What is the bestway to show all information in an one page. I am trying to use create a new viewmodel. But i am not sure about its performance since it is getting all data from tables.

Here are the my model class..

OPPORNUTIES CLASS

            this.CRM_OPP_DETAILS = new HashSet<CRM_OPP_DETAILS>();
        }

        public virtual CRM_VENDORS CRM_VENDORS { get; set; }
        public virtual ICollection<CRM_SOLUTION_VENDOR> CRM_SOLUTION_VENDOR { get;

I started with create a MODELVIEW to show an OPPORTUNITY and related DETAILS at first but i failed ?

Here is my modelview class :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using CRM_V1.Models;

namespace CRM_V1.ViewModels
{
    public class OppViewModel
    {

        public List<CRM_OPPORTUNITIES> OppList { get; set; }
        public List<CRM_OPP_DETAILS> OppDetailList { get; set; }


    }
}

My Controller Action

public ActionResult addingDetailNew(decimal id = 0)
        {
            CRM_OPPORTUNITIES crm_opportunities = db.CRM_OPPORTUNITIES.Find(id);


            var viewModel2 = new OppViewModel
            {
                viewModel2 = db.CRM_OPPORTUNITIES.ToList()

            };



            if (crm_opportunities == null)
            {
                return HttpNotFound();
            }
            return View(viewModel2);
        }

And finally my view.

@model CRM_V1.ViewModels.OppViewModel

@{
    ViewBag.Title = "addingDetailNew";
}

<h2>addingDetailNew</h2>

@Html.DisplayFor(model => model.NOTES)

But i could not get the NOTES field. And my second question how can i get the joined field like model.CUSTOMERS.NAME . ?

您必须在 ViewModel 的 OppList 属性上循环，您必须更新您的视图：

@model CRM_V1.ViewModels.OppViewModel

@{
    ViewBag.Title = "addingDetailNew";
}

<h2>addingDetailNew</h2>

@foreach(CRM_OPPORTUNITIES opportunity in model.OppList) {
    <h3>@opportunity.NOTES</h3>
    @foreach(CRM_OPP_DETAILS detail in opportunity.CRM_OPP_DETAILS){
         <p>@detail.CODE</p>
         <!-- etc... if you want to retrieve more informations -->
    }
}

之后，您可以继续检索所需的对象/属性。

希望有帮助！
