How we use tempdata in controller from another controller in asp.net mvc?

You can pass data from one controller to another in asp.net MVC, Suppose you need to pass value from Index ActionMethod of HomeControlller to Index ActionMethod of Home2Controller

HomeController -Index Method Code will be

public ActionResult Index()
{
    Person data = new Customer()
    {
        Id = 1,
        Name = "Abcd"       
    };
    TempData["mydata"] = data; // save your values in Temp data
    return RedirectToAction("Index", "Home2"); //Call Index ActionMethod of Home2 controller
}

And to get values in Home2Controller using Tempdata, your code will be

public ActionResult Index()
{
    Person data = TempData["mydata"] as Person ; //Get data as Person type
    return View(data);
}

here Person is Model
