Today we will see a small example of how to use SelectedList. It comes under the namespace System.Web.Mvc.
HomeController.cs
Lets have a view Named Index.cshtml
Happy Coding :)
This list basically helps you to represent a list that let user to select item.
To start with we will create a Model say SelectListExampleModel.cs
To start with we will create a Model say SelectListExampleModel.cs
using System;
using System.Collections.Generic;

using System.Web.Mvc;
namespace SubmitTest.Models
{
public class SelectListExampleModel
{
public SelectListExampleModel()
{
if (Items == null)
{
Items = new List<Item>();
}
}
public SelectList ItemList { get; set; }
public List<Item> Items { get; set; }
public int ItemList1 { get; set; }
}
public class Item
{
public int ItemId { get; set; }
public string ItemName { get; set; }
}
}

namespace SubmitTest.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
ViewBag.Message = "Welcome to ASP.NET MVC!";
//Lets create a list of items here
var selectedList = new SelectListExampleModel();
Item item = new Item();
item.ItemId = 1;
item.ItemName = "Bread";
selectedList.Items.Add(item);
Item item1 = new Item();
item1.ItemId = 2;
item1.ItemName = "Butter";
selectedList.Items.Add(item1);
selectedList.ItemList = new SelectList(selectedList.Items, "ItemId", "ItemName");
return View(selectedList);
}
[HttpPost]
public ActionResult Index(SelectListExampleModel model)
{
ViewBag.Message = "Welcome to ASP.NET MVC!";
var selected= model.ItemList1.ToString();
return View(model);
}
public ActionResult About()
{
return View();
}
}
}
Lets have a view Named Index.cshtml
@model SubmitTest.Models.SelectListExampleModel
@{
ViewBag.Title = "Home Page";
}
<h2>@ViewBag.Message</h2>

@using (Html.BeginForm())
