You could try RedirectToAction if you are doing some processing in the first controller and then sending the result to another controller.
View
using(@Html.BeginForm("firstaction", "search", FormMethod.Post)){
// form stuff
}
Controller
public class SearchController
{
[HttpPost]
public ActionResult FirstAction()
{
// do initial processing in the first controller
// e.g persisting changed on Edit Screen
return RedirectToAction("SecondAction","Details");
}
}
public class DetailsController
{
public ActionResult SecondAction()
{
// do remaining processing in the first controller
// fetching data for a grid and displaying the grid of items
return View();
}
}
