ASP.NET Where to place .cs file with enums

Question

I have a file with defined enums. Inside my project, I have a page in which I'd like to use these enums. Where exactly should I save enums file and how is it possible to use it? I tried using statement, but it seems that project doesn't know where is the file located.

Example of Enums.cs

namespace Enums
{
    // 
    [Flags]
    public enum TTDETAILS : long
    {
....

Place this class file in the App_Code folder at your site root. If not present, add this folder your self. This is a special folder in ASP.NET system, which contains stand-alone classes, enums, structures etc.
