Question

ASP.NET front-end .aspx page (hiding code when deployed).

I’m trying to simply have a button for us developers that auto-fills this gigantic form, the only thing I’ve been able to find is this:

<script>
    $(function () {
        <% If (Context.IsDebuggingEnabled) Then %>
            $('#fillForm').show().on('click', function () {
                // nothing special here, loops through items and fills them in
            });
        <% End If %>

        // other normal JS code here
    });
</script>

The problem is when the project is pushed into the live test environment, they still see the button! It starts out as: display:none;, and somehow this code is being hit even on when deployed!

SOLUTION:: Thanks to @Icarus
Test environment web.config also has

<compilation debug="true">

For it to work only within our development environment I had to do:

<% If (System.Configuration.ConfigurationManager.AppSettings("Environment").ToUpper() = " DEVELOPMENT") Then %>
  // stuff here
<% End if %>

That means your Web.config in production still has debug=true in the compilation Section. You should always set the flag to false when deploying to Production. There’s a performance hit, and it may expose more details about exceptions than one would want a user to be able to see.
