Что я уже пробовал:
CS1061: 'ASP.registration_aspx' does not contain a definition for 'ddCountry_SelectedIndexChanged' and no extension method 'ddCountry_SelectedIndexChanged' accepting a first argument of type 'ASP.registration_aspx' could be found (are you missing a using directive or an assembly reference?)
