send data between actions with redirectAction and prg pattern

asp.net-mvc-3

Solution

When redirect you can only pass query string values. Not entire complex objects:

return RedirectToAction("Success", new {
    prop1 = model.Prop1,
    prop2 = model.Prop2,
    ...
});

This works only with scalar values. So you need to ensure that you include every property that you need in the query string, otherwise it will be lost in the redirect.

Another possibility is to persist your model somewhere on the server (like a database or something) and when redirecting only pass the id which will allow to retrieve the model back:

int id = StoreModel(model);
return RedirectToAction("Success", new { id = id });

and inside the Success action retrieve the model back:

public ActionResult Success(int id)
{
    var model = GetModel(id);
    ...
}

Yet another possibility is to use `TempData` although personally I don't recommend it:

TempData["model"] = model;
return RedirectToAction("Success");

and inside the `Success` action fetch it from `TempData`:

var model = TempData["model"] as PersonalDataViewModel;

Problem

how can i send data between actions with redirectAction?? I am using PRG pattern. And I want to make something like that ``` [HttpGet] [ActionName("Success")] public ActionResult Success(PersonalDataViewModel model) { //model ko if (model == null) return RedirectToAction("Index", "Account"); //model OK return View(model); } [HttpPost] [ExportModelStateToTempData] [ActionName("Success")] public ActionResult SuccessProcess(PersonalDataViewModel model) { if (!ModelState.IsValid) { ModelState.AddModelError("", "Error"); return RedirectToAction("Index", "Account"); } //model OK return RedirectToAction("Success", new PersonalDataViewModel() { BadgeData = this.GetBadgeData }); } ```
