You could create a UserControl base class with the common properties. The properties would need to wrap a session variable, which would be common to each.

eg:

public string Text
        {
            get
            {
                if (Session["UserControlText"] == null || Session["UserControlText"].ToString().Trim() == String.Empty)
                {
                    Session["UserControlText"] = String.Empty;
                }

                return Session["UserControlText"].ToString().Trim();
            }
            set
            {
                Session["UserControlText"] = value;
            }
        }
