MVC3: PRG Pattern with Search Filters on Action Method

Question

I have a controller with an Index method that has several optional parameters for filtering results that are returned to the view.

public ActionResult Inde         


        

Answer 1

A redirect is just an ActionResult that is another action. So if you had an action called SearchResults you would simply say

return RedirectToAction("SearchResults");

If the action is in another controller...

return RedirectToAction("SearchResults", "ControllerName");

With parameter...

return RedirectToAction("SearchResults", "ControllerName", new { parameterName = model.PropertyName });

Update

It occurred to me that you might also want the option to send a complex object to the next action, in which case you have limited options, TempData is the preferred method

Using your method

[HttpPost]
public ActionResult Index(ViewModel model) {
    ...
    if (ModelState.IsValid) {
        product = repository.GetProducts(model);
        TempData["Product"] = product;
        return RedirectToAction("NextAction");
    }
    return View(model);
}

public ActionResult NextAction() {
    var model = new Product();
    if(TempData["Product"] != null)
       model = (Product)TempData["Product"];
    Return View(model);
}
