Working on an MVC site that was constructed by another developer, who has now left. I'm not that hot on MVC, so apologies if this is a terrible question.
Among the controllers for this site there is an ErrorController. It has two associated Views held in \Views\Error. The controller doesn't do much:
public class ErrorController : Controller
{
public ActionResult NotFound()
{
Response.StatusCode = 404;
return View("NotFound");
}
public ActionResult Error()
{
return View("Error");
}
}
I'm trying to extend this controller so I can pass in an error message and inform the user, but I'm struggling to understand how I can pass a parameter to it when I'm calling from a different controller. So, for example this:
public class ManagerController : Controller
{
public ActionResult SubmitDetails()
{
if (ModelState.IsValid)
{
// do stuff and return a View
}
//if we get this far, we've got an error or an invalid state
return View("../Error/Error");
}
}
Render the error view. But if add this to the ErrorController:
public ActionResult Error(string errorMessage)
{
ViewBag.ErrorMessage = errorMessage;
return View("Error");
}
I don't know how I can call that from an action in a different controller. Variants on the theme of:
return View("../Error/Error", "test error message");
Results in an error: The view '../Error/Error' or its master was not found or no view engine supports the searched locations.
How can I pass a message, or better yet an object with a bunch of messages, down to the controller? Or am I going about this the wrong way - the full error messages suggests I should perhaps be using a shared view instead?
return RedirectToAction("Error", "Error", new { errorMessage = "...." });
