If you already have a List with all checked/unchecked properties and just want to show the checked records in a new view, you can store your list in a TempData and redirect to an action which will use your list:
public ActionResult Index()
{
return View(db.Products.ToList());
}
[HttpPost]
public ActionResult Index(List<Product> list)
{
TempData["CheckedRecords"] = list.Where(x=>x.Checked).ToList(); //Don't forget to add 'using System.Linq;'!
return RedirectToAction("MyOtherView");
}
public ActionResult MyOtherView()
{
var checkedRecords = (List<Product>)TempData["CheckedRecords"];
return View(checkedRecords);
}
