Answer 1

RedirectToAction with parameter:

return RedirectToAction("Action","controller", new {@id=id});

Answer 2

If one want to Show error message for [httppost] then he/she can try by passing an ID using

return RedirectToAction("LogIn", "Security", new { @errorId = 1 });

for Details like this

 public ActionResult LogIn(int? errorId)
        {
            if (errorId > 0)
            {
                ViewBag.Error = "UserName Or Password Invalid !";
            }
            return View();
        }

[Httppost]
public ActionResult LogIn(FormCollection form)
        {
            string user= form["UserId"];
            string password = form["Password"];
            if (user == "admin" && password == "123")
            {
               return RedirectToAction("Index", "Admin");
            }
            else
            {
                return RedirectToAction("LogIn", "Security", new { @errorId = 1 });
            }
}

Hope it works fine.

Answer 3

I had this issue as well, and quite a nice way to do it if you are within the same controller is to use named parameters:

return RedirectToAction(actionName: "Action", routeValues: new { id = 99 });

Answer 4

It is also worth noting that you can pass through more than 1 parameter. id will be used to make up part of the URL and any others will be passed through as parameters after a ? in the url and will be UrlEncoded as default.

e.g.

return RedirectToAction("ACTION", "CONTROLLER", new {
           id = 99, otherParam = "Something", anotherParam = "OtherStuff" 
       });

So the url would be:

    /CONTROLLER/ACTION/99?otherParam=Something&anotherParam=OtherStuff

These can then be referenced by your controller:

public ActionResult ACTION(string id, string otherParam, string anotherParam) {
   // Your code
          }

Answer 5

If your need to redirect to an action outside the controller this will work.

return RedirectToAction("ACTION", "CONTROLLER", new { id = 99 });

Answer 6

....

int parameter = Convert.ToInt32(Session["Id"].ToString());

....

return RedirectToAction("ActionName", new { Id = parameter });
