Witam
Otóż mam taki problem stworzyłam klasę konto z trzema zmiennymi nazwa, nr, saldo. Zrobiłam listbox-a aby można było widzieć dodane konta. I teraz tak mam w kodzie xaml.cs dodane trzy obiekty klasy Konto i mimo iż coś tam jest to nie są one wyswietlane. Może wiecie jak to naprawić. Myślałam że to kolor czcionki ale to nie o to chodzi. Nie mam juz pomysłów. Poniżej kody xaml, xaml.cs i klasa
