How to disable detailed "Compilation Error" output in web page

Question

I would like to disable the detailed "Compilation Errors" page that is displayed when an error occurs on my ASP.NET website. It shows:

• Title: "Compilation Error"
• Description
• Compiler Error Message
• Source Error (yellow box with the detailed line number and code error highlighted in red)
• Source File
• "Show Detailed Compiler Output"

Here's what I've already attempted:

• Within the ASP icon in IIS, set the "Enable Log Error Requests" to false at both site and app pool levels.
• Within the ASP icon in IIS, set the "Enable Server-side Debugging" to false at both site and app pool levels.
• Within the Error Pages icon in IIS, click "Edit Feature Settings...", select "Detailed errors" at both site and app pool levels.
• Within the web.config file, set "compilation debug=false"
• Within the web.config file, set "customErrors mode=Off"

Ideally, I'd like not to reveal the Compilation Error. So, I'd like to know: a) how to disable these details from being displayed and show the default, and/or b) how to show my custom errors page, instead. Thank you.

You can customize it inside the web.config:

<customErrors defaultRedirect="GenericError.htm"
              mode="On">
  <error statusCode="500"
         redirect="InternalError.htm"/>
</customErrors>
