Custom error page not getting called

Question

I need to implement my own custom error page in MVC 4. Basically when users try to view Details of any product with non-existent productID, I want this custom error page.

I created my own custom error page NotFound.aspx

The inside content of this page is :

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Simple.Master" 
Inherits="System.Web.Mvc.ViewPage<System.Web.Mvc.HandleErrorInfo>" %> 
<asp:Content ID="errorTitle" ContentPlaceHolderID="TitleContent" runat="server"> 
Error 
</asp:Content> 
<asp:Content ID="errorContent" ContentPlaceHolderID="MainContent" runat="server"> 
<h2> 
Sorry, you requested a product that doesn't exist. Make sure you
requested a valid ProductID 
</h2> 
</asp:Content>

And then Applied the HandleError filter to my ActionMethod: Details as:

[HandleError(View="NotFound")] 
public ActionResult Details(int id) {...

The problem is that, Always the default view : Views/Shared/Error.aspx is being called and not the new custom error page. Any thoughts ?

Answer 1

Try this (but i am not sure about working of this code in MVC). Paste this code in configuration section in web.config file brlow system.web.

 <customErrors mode="On" defaultRedirect="ErrorPage.aspx">
    </customErrors>
    <compilation debug="true" targetFramework="4.0">

Try using custom errors tag found in the web config file that might help you.

Here is the sample

<system.web>
   <--- other required may be used here--->     

    <customErrors mode="On" defaultRedirect="ErrorPage.aspx"></customErrors>
  </system.web>

The solution is that my ProductController class also needs to have the order property set as:

[HandleError(Order=2)] 
public class ProductController : Controller { ... }

What this means: An Order value of 2 will ensure that the controller-wide filter will be applied only if there isn’t a HandleError filter with a higher order available.

And this worked perfectly. My web.config setting are: <customErrors mode="On" /> .

This is it. The defaultRedirect is not needed at all.

NOTE: I had the HandleError filter initially with NO order property.

[HandleError] 
public class ProductController : Controller { ... }

When you apply the HandleError filter with no arguments, you are specifying that any exception thrown by the methods covered by the filter will result in the Views/Shared/Error.aspx view being used.
