VS'12 KendoUI InternetApplication Template C＃asp.net EF Code First

我的问题是如何pass Regular（现在正在传递）值和Ienumerable（传递null）到我的controller并将它们保存到Databas {1}}在EF Code First庄园中使用Many-2-Many Relationship。

以下是我的尝试

主视图

@model OG.Models.UserProfiles

@using (Html.BeginForm())
{   

     <div class="editor-field">

        <div class="Containter">
        <div>
             @Html.DisplayFor(model => model.UserName)
        </div>

             <div class="contentContainer">
             @foreach (var item in Model.Prospects)
             {
                 <table>
                     <tr>
                         <td>
                             @Html.Label("Current Prospects")
                        </td>
                     </tr>
                     <tr>
                         <td>
                            @Html.DisplayNameFor(x=>item.ProspectName)
                         </td>
                     </tr>
                 </table>
             }

           </div>

         </div>

        <div class="contentContainer2">
             @Html.Partial("_UsersInProspectsDDL", new  OG.ModelView.ViewModelUserInProspects() { Users = Model.UserName })
        </div>

    </div>
}

部分视图

 @model OG.ModelView.ViewModelUserInProspects

            <label for="prospects">Prospect:</label>
            @(Html.Kendo().DropDownListFor(m=>m.Prospects)
                  .Name("Prospects")
                  .HtmlAttributes(new { style = "width:300px"}) //, id = "countys"})
                  .OptionLabel("Select Prospect...")
                  .DataTextField("ProspectName")
                  .DataValueField("ProspectID")
                  .DataSource(source => {
                      source.Read(read =>
                      {
                          read.Action("GetCascadeProspects", "ChangeUsersInfo")
                              .Data("filterProspects");
                      })
                      .ServerFiltering(true);
                  })
                  .Enable(false)
                  .AutoBind(false)
                  .CascadeFrom("Clients")

</div>

PartialView模型

public class ViewModelUserInProspects
    {
    public string Clients { get; set; }
    public IEnumerable<dbClient> AvailableClients { get; set; }
    public string Prospects { get; set; }
    public IEnumerable<dbProspect> AvailableProspects { get; set; }

    public string Users { get; set; }
    public IEnumerable<UserProfiles> AvailableUsers {get;set;}

    }
}

主要模式
```
Standart SimpleMemberShipUserTable
```

发布方法

[HttpPost]
public ActionResult UsersInProspect(
    [Bind(Include= "ProspectName, ProspectID")]
    UserProfiles userprofiles, ViewModelUserInProspects values, FormCollection form) 
    //<- Trying different things sofar 
{
    if (ModelState.IsValid)
    {

        //string something = form["Prospects"];
        int prosID = Convert.ToInt16(values.Prospects);
        int  UserID = userprofiles.UserID; // <- THIS VALUE is null atm.

这是我需要将ID保存到EF生成/映射表的地方。不确定如何。

            db.Entry(userprofiles).CurrentValues.SetValues(userprofiles);

            db.Entry(userprofiles).State = EntityState.Modified;
            db.SaveChanges();
            return RedirectToAction("Index");
        }
        return View(userprofiles);
    }
