If you are wanting to keep the variable hidden then you could use a session to store your object.

E.g.,

Setting the session value

Session["HiddenValue"] = "something";

Getting the session value

string something =  (string)Session["HiddenValue"];

Do keep in mind however, that sessions are only for a limited time (this can be configured thorugh IIS and your web configuration).

Here is a good resource to learn about sessions and session state.
