This article shows you how to use a DisplayTextfor helper to handle HttpPost operations in MVC applications.

Create an ASP.Net Web Application as in Figure 1.

Choose MVC template as in Figure 2.

 

Figure 2: MVC template

Setup Entity Framework as shown in Figures 3, 4 and 5.

 

Figure 3: Add ADO.NET Entity Framework

Figure 5: Select Tables

Add an Employee Controller as shown in Figures 6, 7 and 8.

 

Figure 6: Add controller

Figure 8: EmployeeController

EmployeeController.cs

using DisplayTextForMVCPost_App.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web;
using System.Web.Mvc;

namespace DisplayTextForMVCPost_App.Controllers
{
    public class EmployeeController : Controller
    {

        EmployeeEntities db = new EmployeeEntities();
        //
        // GET: /Employee/
        public ActionResult Index()
        {
            return View(db.Departments.ToList());
        }

        [HttpPost]
        public string Index(IEnumerable<Department> dpt)
        {
            StringBuilder sb = new StringBuilder();
            foreach (var item in dpt)
            {
                sb.Append("The list of departments: <b>" + item.DepartmentName + "</b>");
                sb.Append("<br />");
            }

            return sb.ToString();
        }
    }
}

Add a View as Figure 9.

 

Figure 9: Add Index View

Index.cshtml

@model  IList<DisplayTextForMVCPost_App.Models.Department>

@{
    Layout = null;
}

@using (Html.BeginForm("Index", "Employee", FormMethod.Post))
{

    for (int i = 0; i < Model.Count; i++)
    {
        @Html.HiddenFor(m => m[i].DepartmentName)
        @Html.DisplayTextFor(m => m[i].DepartmentName)
        <br />
    }
    <br />
    <input type="submit" value="Submit" />
}

The output of the application is as in Figure 10.
