Question

How would you pass the model from an (GetDate) action to another (ProcessP) action via RedirectAction method?

Here’s the source code:

[HttpPost]
public ActionResult GetDate(FormCollection values, DateParameter newDateParameter)
{
    if (ModelState.IsValid)
    {
return RedirectToAction("ProcessP");
    }
    else
    {
return View(newDateParameter);
    }
}


public ActionResult ProcessP()
{
   //Access the model from GetDate here??
    var model = (from p in _db.blah
 orderby p.CreateDate descending
 select p).Take(10);

    return View(model);
}

If you need to pass data from one action to another one option is to utilize TempData. For example within GetDate you could add data to the session as follows:

TempData["Key"] = YourData

And then perform the redirect. Within ProcessP you can access the data utilizing the key you previously used:

var whatever = TempData["Key"];
