I've got a web app with an Employee page which doubles as both "Add New" or "Edit" edit modes. In my Business Object (BO) I have an EmployeeRules.partial.cs where I have my own custom validation rules that I want to run differently depending on which edit mode I'm in. The web page will have the knowledge as to which edit mode I'm currently in.

What global object exists in both places?

No, the web Session object doesn't exist in the BO rules object.

Nor does the appWeb object exist in the BO rules object.

What object/class is available to me for communicating which edit mode I'm currently in so I can run a different set of validation rules?
