问题 I am building a simple search, sort, page feature. I have attached the code below. Below are the usecases: My goal is to pass the "current filters" via each request to persist them particularly while sorting and paging. Instead of polluting my action method with many (if not too many) parameters, I am thinking to use a generic type parameter that holds the current filters. I need a custom model binder that can be able to achieve this. Could someone please post an example implementation? PS: I

In my Controller I created 2 action methods: Import and Export. How could I manage to redirect each button click to the proper action method in my Controller?

问题 Can anybody please tell me why should I use NonAction? I mean say I have a form with several submit values: Update, Delete or Insert. Since all the submit buttons have the same form in common I'm switching the submit value inside the controller and act accordingly. Like this: public ActionResult asd(string submitButton){ switch(submitButton){ case "Insert": return Insert(); // bla bla bla } } [NonAction] public ActionResult Insert(){ // some code inside here return View(); } Once again, why

Maybe some kind of annotation, modification in the route configuration? Which are my options? 回答1: If you are going to use this action only from within your controller or Views then you can use ChildActionOnly attribute.
