In my last article I explain how to send data from view to controller using ViewData. ViewBag is also used to pass data from controller to its corresponding view. ViewBag used dynamic property which introduced in C# 4.0.
It is actually a dynamic ViewData Dictionary so you can say that it’s just a wrapper around ViewData.
Create a controller name Home and create view name Index. In this view create a list of type string in which stores the Department Name.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MvcApplication5.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
List<string> dept = new List<string>()
{"HR","Sales","Developer"};
ViewBag.dept_name = dept;
return View();
}
}
}
In this example we create dynamic property named dept_name. Now use this ViewBag in View
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<div>
Employee Departments are:-<br />
@foreach (string dept in ViewBag.dept_name)
{
<p><b>@dept</b></p>
}
</div>
</body>
</html>
As you can see that we need not to perform the type casting while working with ViewBag.
The output of this code will be as follows:-
