               new SqlParameter("@UserName",SqlDbType.NVarChar)
            };

        paramdizi[0].Value = Session["Username"];

        Baglanti baglanti = new Baglanti();

        SqlDataReader dr = baglanti.ExecuteReader("MenuGetir", CommandType.StoredProcedure, paramdizi);

        List<MenuBilgi> liste = new List<MenuBilgi>();

        while (dr.Read())
        {
            MenuBilgi bilgi = new MenuBilgi(dr.GetString(0), dr.GetString(1));
            liste.Add(bilgi);
        }

        NavigationMenu.DataSource = liste; NavigationMenu.DataBind();
    }
}
