如何从Controller发送CustomerName和CustomerSurname来编辑或创建cshtml [英] How to send CustomerName and CustomerSurname from Controller to edit or create cshtml

问题描述

我想从Controller发送CustomerName和CustomerSurname来编辑或创建cshtml，但是我收到错误：

System.Data。 Entity.DynamicProxies.CUSTOMERS_14601EA232CC1C78E8EEE3B8325EDF47D2BEC1CCBF414A98771B931D28B27715'
不包含名称为CustomerName
CustomerSurname的属性。

控制者

  // GET：PAYMENT / Create 
 public ActionResult Create（）
 {
 ViewBag.PaymentCustomer = new SelectList（db.CUSTOMERS，CUSTID，CustomerName++CustomerSurname）; 
 return View（）; 
} 
  

CSHTML

  @ Html.ValidationSummary（true）
< div class =form-group> 
 @ Html.LabelFor（model => model.PaymentCustomer，PaymentCustomer，htmlAttributes：new {@class =control-label col-md-2}）
< div class = COL-MD-10\" > 
 @ Html.DropDownList（PaymentCustomer，String.Empty）
 @ Html.ValidationMessageFor（model => model.PaymentCustomer）
< / div> 
< / div> 
  

有谁知道如何使用列名作为一个？
CustomerName++CustomerSurname

当尝试使用控制器/编辑编辑

  // GET：PAYMENT / Edit / 5 
 public ActionResult Edit（int？id）
 {
 if （id == null）
 {
 return new HttpStatusCodeResult（HttpStatusCode.BadRequest）; 
} 
 PAYMENT pAYMENT = db.PAYMENT.Find（id）; 
 if（pAYMENT == null）
 {
 return HttpNotFound（）; 
} 
 ViewBag.PaymentCustomer = new SelectList（db.CUSTOMERS，CUSTID，CustomerName，pAYMENT.PaymentCustomer）; 
 ViewBag.PaymentLocation = new SelectList（db.LOCATION，LOCID，LocationName，pAYMENT.PaymentLocation）; 
 return View（pAYMENT）; 
} 
  

编辑视图

 < div class =form-group> 
 @ Html.LabelFor（model => model.PaymentCustomer，PaymentCustomer，htmlAttributes：new {@class =control-label col-md-2}）
< div class = COL-MD-10\" > 
 @ Html.DropDownList（PaymentCustomer，String.Empty）
 @ Html.ValidationMessageFor（model => model.PaymentCustomer）
< / div> 
< / div> 
  

解决方案

您可以生成 IEnumerable< SelectListItem> 并设置 Text 属性

  ViewBag.PaymentCustomer = db.CUSTOMERS.ToList（）。选择（c => new SelectListItem 
 {
 Value = c.CUSTID.ToString（），
 Text = string.Format {0} {1}，c.CustomerName，c.CustomerSurname）
}）; 
 return View（）; 
  

I want to send CustomerName and CustomerSurname from Controller to edit or create cshtml but I am getting error as:

System.Data.Entity.DynamicProxies.CUSTOMERS_14601EA232CC1C78E8EEE3B8325EDF47D2BEC1CCBF414A98771B931D28B27715' does not contain a property with the name 'CustomerName CustomerSurname'.

The Controler

// GET: PAYMENT/Create
public ActionResult Create()
{
    ViewBag.PaymentCustomer = new SelectList(db.CUSTOMERS, "CUSTID", "CustomerName" + " " + "CustomerSurname");
    return View();
}

The CSHTML

@Html.ValidationSummary(true)
<div class="form-group">
    @Html.LabelFor(model => model.PaymentCustomer, "PaymentCustomer", htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @Html.DropDownList("PaymentCustomer", String.Empty)
        @Html.ValidationMessageFor(model => model.PaymentCustomer)
    </div>
</div>

Does anyone knows how to use both column name as one? "CustomerName" + " " + "CustomerSurname"

And when try to edit with controller/edit

 // GET: PAYMENT/Edit/5
        public ActionResult Edit(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            PAYMENT pAYMENT = db.PAYMENT.Find(id);
            if (pAYMENT == null)
            {
                return HttpNotFound();
            }
            ViewBag.PaymentCustomer = new SelectList(db.CUSTOMERS, "CUSTID", "CustomerName", pAYMENT.PaymentCustomer);
            ViewBag.PaymentLocation = new SelectList(db.LOCATION, "LOCID", "LocationName", pAYMENT.PaymentLocation);
            return View(pAYMENT);
        }

Edit View:

    <div class="form-group">
        @Html.LabelFor(model => model.PaymentCustomer, "PaymentCustomer", htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.DropDownList("PaymentCustomer", String.Empty)
            @Html.ValidationMessageFor(model => model.PaymentCustomer)
        </div>
    </div>

解决方案

You can generate IEnumerable<SelectListItem> and set the Text property

ViewBag.PaymentCustomer = db.CUSTOMERS.ToList().Select(c => new SelectListItem
{
  Value = c.CUSTID.ToString(),
  Text = string.Format("{0} {1}", c.CustomerName, c.CustomerSurname)
});
return View();
