Cannot resolve view of the parent controller

Question

Create a controller:

public abstract class MyBaseController : Controller
{
   public ActionResult MyAction(string id)
   {
      return View();
   }
}

Than create another specific controller that inherit from MyBaseController:

public class MyController : MyBaseController 
{

}

There is a view called MyAction.aspx in the Views/MyBaseController folder Then, call MyController/MyAction method. Following exception will be generated:

The view 'MyAction' or its master could not be found. The following locations were searched: ~/Views/MyController/PhConnect.aspx ~/Views/MyController/PhConnect.ascx ~/Views/Shared/MyAction.aspx ~/Views/Shared/MyAction.ascx

Can I make MVC.NET to use the view from Views/MyBaseController folder?

Answer 1

You need to add it to shared because you are in the context of the subcontroller. If you want different behavior for different controllers, then you'll want to put a MyAction view in each of your subcontroller view folders.

To answer your question though, you probably could make it look in base controller folder, but it would require you to write your own request handler which looks in base controller folders. The default implementation only looks in the view folder for the current controller context, then it looks in the shared folder. It sounds like your view is shared however, so the shared folder seems like a good place for it anyway.

Answer 2

It is possible, but not very clean.

public class MyController : MyBaseController 
{
   public ActionResult MyAction(string id)
   {
       return View("~/Views/MyBaseController/MyAction.aspx");
   }
}

However if your View (MyAction.aspx) contains a reference to a Partial View, ASP.NET MVC will look for it in the Views/MyController folder (and not find it there!).

If your view is shared across controllers, its best to place it in the Views/Shared folder as recommended by NickLarsen.
