 ASP.NET MVC  Provide Three Different Type of Objects to Store data and send it into View.

1)  ViewData:-   It is used to store data using key=>value pair, the key is used to provide identity, and data is used to store value.


It Stores data in Object pattern and its scope will be the same controller to view (same request).

After Redirection Value will be null of ViewData Object.

2)  ViewBag:-   It is used to store data in Object pattern, It's scope will be the same  controller to the same view similar to ViewData but it is used to manage datatype of assigned data implicit.

ViewBag.a=10  //Int   

3) TempData:-   It is used to store data in Object pattern, It's scope will be the same controller to different view means it will work on cross request, After Redirection, we can store data under TempData Object.


TempData["a"]=100;  //Object pattern

TempData not manage datatype,it stores all data in Object pattern.

TempData.keep()  is used to store data permanently

Practical Implementation of ViewBag, ViewData, and TempData:-

Create a Controller with the Get method

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace BasicMVCExample.Controllers
    public class ObjectDataController : Controller
        // GET: /ObjectData/

        public ActionResult Index()
            ViewData["key1"] = 10;
            ViewBag.key = 111;
            TempData["key"] = 23;
           // return View();
            return RedirectToAction("Method2");

        public ActionResult Method2() {
           // TempData.Remove("key");

            return View();


Create View for method2.cshtml

    Layout = null;

<!DOCTYPE html>

    <meta name="viewport" content="width=device-width" />
