How to pass values from One controller to another Controller in ASP.Net MVC3

Question

Hello In my project I have to pass a welcome message with username to the Index Page Its a MVC3 ASP.Net Razor project

There are two controllers are there; O

Answer 1

1. Change the Index() method of Home Controller to this:

   [HttpPost]
   
   public ActionResult Index(string username)
   {
        ViewBag.user=username; 
        return View();
   }
   

2. Modify the Login Controller :

   if (DataAccess.DAL.UserIsValid(model.UserName, model.Password))
   {
       FormsAuthentication.SetAuthCookie(model.UserName, false); 
       return RedirectToAction("Index", "Home",new { username = model.Username } ); 
       //sending the parameter 'username'value to Index of Home Controller
   }
   

Go to the View Page of the Index method of Home Controller and add the following:

 
User is: @ViewBag.user

And you're done. :)
