Mvc - 下拉列表中选择列表中的多个字段 [英] Mvc - multiple fields in selectlist for dropdownlistfor

问题描述

嗨


我试图将多个字段放在填充DropDownList的SelectList中。



我可以使用以下代码填写清单。

控制器

Hi
I am trying to put multiple fields in a SelectList that populates a DropDownList.

I can populate the list fine with the below code
Controller

var product = new ProductService().ProductByClubView(clubname.Trim()).ToList();
ViewBag.ProductList = new SelectList(product, "prodname", "prodname");

public IEnumerable<Product> ProductByClubView(string clubname)
        {
            var context = new dbS4CEntities(myprop.Connection);

            var result = from a in context.Product
                         where a.clubname.Trim() == clubname.Trim()
                         orderby a.id descending
                         select a;

            return result;
        }

查看

View

@model S4C.Models.PaymentView2Model

@using (Html.BeginForm("Payment2", "Home", FormMethod.Post))
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })


        <div class="form-group">
            Product
            <div class="col-md-10">
                @Html.DropDownListFor(model => model.prodname, (SelectList)ViewBag.ProductList, new { @style = "width:400px; text-align: left", @class = "btn btn-default dropdown-toggle" })
            </div>
        </div>

        
    </div>

}

这将选择属于俱乐部的产品。

我想要下拉框来获取产品和金额。



我尝试过：



所以我认为以下代码可行。

This selects the products that belong to a club.
I want the drop down box to grab the products and the amount.

What I have tried:

So I thought the below code would work.

var product = new ProductService().ProductByClubView(clubname.Trim()).ToList();


               var result = db.Product
                   .Where(x => x.clubname == clubname.Trim())
                   .Select(x => new
                   {
                       prodname= x.prodname,
                       Name = x.prodname + " - $" + x.amount.ToString()
                   });

               ViewBag.ProductList = new SelectList(product, "prodname" , "Name" );

但是，我收到一个错误System.Web.HttpException：DataBinding：'S4C.Models.Product'不包含名称为'的属性姓名'



如何将多个字段绑定到下拉列表？

However, I am getting an error System.Web.HttpException: DataBinding: 'S4C.Models.Product' does not contain a property with the name 'Name'

How do I bind multiple fields to a dropdownlist?

推荐答案

+ x.amount.ToString（）
}）;

ViewBag.ProductList = new SelectList（product， prodname， Name）;

" + x.amount.ToString() }); ViewBag.ProductList = new SelectList(product, "prodname" , "Name" );

但是，我收到一个错误System.Web.HttpException：DataBinding：'S4C.Models。产品'不包含名称为'Name'的属性

var product = new ProductService（）。ProductByClubView（clubname.Trim（））。ToList（）;





var 结果 product = db.Product

.Where（x => x.clubname == clubname.Trim（））

。选择（x =>新

{

prodname = x.prodname，

Name = x.prodname + -

var product = new ProductService().ProductByClubView(clubname.Trim()).ToList();


var result product = db.Product
.Where(x => x.clubname == clubname.Trim())
.Select(x => new
{
prodname= x.prodname,
Name = x.prodname + " -

+ x.amount.ToString（）

}）;



ViewBag.ProductList = new SelectList（product，prodname，Name）;

" + x.amount.ToString()
});

ViewBag.ProductList = new SelectList(product, "prodname" , "Name" );
