如何选择下拉MVC [英] How to get select drop down MVC

问题描述

我有数据收集



i想要根据以前的选择选择ddl



< pre lang =HTML> @for（int i = 0; i < Model.listAddressEnity.Count; i ++）

{

@ Html.DropDownListFor（x = > x.listAddressEnity [i] .City_ID，（SelectList）ViewBag.City_ID）
}

  var  selectList =  new  SelectList（objCityHandler.SP_GET_CITY（）。选择（s = >   new  {Id = s.City_ID，Name = s.City_Name}），  Id， 名称 ）; 
 ViewBag.City_ID = selectList; 
 

我的问题是列表中的数据



否单个数据中的问题

  var  selectList =  new  SelectList（objCategoryHandler.SP_GET_CATEGORY（）。选择（s = >   new  {Id = s。 Categoty_ID，Name = s.Category_Name}），  Id， 名称，objProductCollectionEntity.ProductEntity.Categoty_ID）; 
 

但如何选择List

解决方案

将列表数据绑定到下拉列表

  @ Html  .DropDownList（< span class =code-string>  Country， ViewBag.City_ID  as  SelectList ，
  选择城市，new {style = < span class =code-string>  width：200px}）

如何在MVC中获取Controller中的下拉值 [ ^ ]

i have collection of data

i want to select ddl on basis of previous selection

   @for (int i = 0; i < Model.listAddressEnity.Count; i++)

                    {

     @Html.DropDownListFor(x => x.listAddressEnity[i].City_ID, (SelectList)ViewBag.City_ID)
}

var selectList = new SelectList(objCityHandler.SP_GET_CITY().Select(s => new { Id = s.City_ID, Name = s.City_Name }), "Id", "Name");
               ViewBag.City_ID = selectList;

My problem is data in List

No problem in single data

var selectList = new SelectList(objCategoryHandler.SP_GET_CATEGORY().Select(s => new { Id = s.Categoty_ID, Name = s.Category_Name }), "Id", "Name", objProductCollectionEntity.ProductEntity.Categoty_ID);

but how to do selection with List

解决方案

Bind List data to dropdownlist

@Html.DropDownList("Country", ViewBag.City_ID as SelectList,
         "Select City", new { style = "width:200px" })

see this.. :)
