In MVC the views that are not called by the specific controller ActionMethod

Below are the ways, the views are not called by the controller actionMethod.

Method 1: Having the common folder called shared. Views in shared folder donot require a controller actionMethod. When ever an action method executes and returns a view that is not located in its path. Then it will check the shared folder by that view name.

Ex: return view("NoData")

Here the NoData is searched in shared folder if is not located in the views folder corresponding to that controller.

Method 2: If there are 100 views with some static data, then does it make sense in creating 100 actionMethods in controller. Obviously no, in such a case, the MVC framework helps us with the method HandleUnknownAction that executes whenever an attempt to invoke the action method that doesnot exist.

        protected override void HandleUnknownAction(string actionName)

        {

            try

            {

                this.View(actionName).ExecuteResult(this.ControllerContext);

            }

            catch(Exception ex)

            {

                Response.Redirect("PageNotFound");

            }

        }

Code Snippet:

    public class HomeController : Controller

    {

        protected override void HandleUnknownAction(string                                                                  actionName)

        {

            try

            {                                           this.View(actionName).ExecuteResult(this.ControllerContext);

            }

            catch(Exception ex)

            {

                Response.Redirect("PageNotFound");

            }

        }

        public ActionResult Index()

        {

            return View();

        }       

    }
