Post-Redirect-Get issue in MVC3 - asp.net-mvc-3

Question

I need to use Post-Redirect-Get to show data, which I entered in "Information" page on "Index" page. I have the following methods, but it doesn't work. It doesn't even redirect me on submit. What am I doing wrong?
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
public ActionResult About()
{
return View();
}
public ActionResult Information()
{
return View();
}
//Get info
[HttpGet]
public ActionResult Submit(Models.Information FirstName,
Models.Information LastName,
Models.Information DateOfBirth,
Models.Information HourOfBirth,
Models.Information NumberOfKids,
Models.Information Emso,
Models.Information Email,
Models.Information PlaceOfBirth)
{
if (ModelState.IsValid)
{
Models.Information info = new Models.Information();
info.FirstName = FirstName.ToString();
info.LastName = LastName.ToString();
info.DateOfBirth = Convert.ToDateTime(DateOfBirth);
info.HourOfBirth = Convert.ToDateTime(HourOfBirth);
info.NumberOfKids = Convert.ToInt32(NumberOfKids);
info.Emso = Emso.ToString();
info.Email = Email.ToString();
info.PlaceOfBirth = PlaceOfBirth.ToString();
TempData["info"] = info;
return RedirectToAction("Summary");
}
return View();
}
//Show info
[HttpPost]
public ActionResult Post(Models.Information info)
{
info.FirstName = ViewData["FirstName"].ToString();
info.LastName = ViewData["LastName"].ToString();
info.DateOfBirth = Convert.ToDateTime(ViewData["DateOfBirth"]);
info.HourOfBirth = Convert.ToDateTime(ViewData["HourOfBirth"]);
info.NumberOfKids = Convert.ToInt32(ViewData["NumberOfKids"]);
info.Emso = ViewData["Emso"].ToString();
info.Email = ViewData["Email"].ToString();
info.PlaceOfBirth = ViewData["PlaceOfBirth"].ToString();
return View();
}
}
I try to show data on Index page like this:
First name: <input type='text' runat="server" value="#ViewData["FirstName"]" /><br />

Your code looks sort of confusing to me and I am not sure what you are trying to accomplish. But first, let's use an example on what I think you are trying to accomplish.
User enters information on the information action/view
(POST)This is POSTed to a controller/action which then verifies the model and puts in into the ViewData (REDIRECT TO STEP 3)
(GET)You want to redisplay this data on a summary page.
Under those assumptions, lets clean up your code a bit, leverage the use of the ViewData and TempData objects and see if we can make this work.
Information Action
public ActionResult Information()
{
//In a strongly typed view, typically you would send an empty model
//so the model binder/Html.Input helpers have something to bind to
return View(new Models.Information());
}
Information POST to handle incoming data
[HttpPost]
public ActionResult Information(Models.Information info)
{
//Yup - you can use the same action name as the GET action above
//You can name this anything you want, but I typically keep the same names so
//I know where the data came from
//I think your assignments are backwards. info came into the controller action
//You want to save this as ViewData. Also, let's do that in one line of code
//And since we are redirecting, lets use the TempData dictionary
//Notice the method type decorator above [HttpPost]. This is the P in PRG (Post)
if(modelState.IsValid()){
TempData["info"] = info;
//Notice the name of the ActionMethod below. The is the R in PRG (Redirect)
return RedirectToAction("Summary");
}
//There were errors, lets send back to the Information view
return View(info);
}
Summary Action
public ActionResult Summary()
{
//We were redirected here, and this is a GET method. This is the G in PRG
//(GET)
//lets go ahead and set the TempData stuff to a model, it just looks nicer on
//the view
var model = TempData["info"];
return View(model);
}
As for the views, here is a snippet of what each might look olike
Information View
#model Models.Information
#{using(Html.BeginForm()){
#Html.LabelFor(x=>x.FirstName)<br/>
#Html.TextBoxFor(x=>x.Firstname)
//Repeat for each property
<input type="Submit" value="Submit"/>
}}
Summary View
#model Models.Information
#Html.LabelFor(x=>x.FirstName)<br/>
#Html.DisplayFor(x=>x.Firstname)
//Repeat for each property
