GridDesktop için Yükleme Olayı
Aşağıdaki örnek kod, bir dosya içeri alırken GridDesktop için çeşitli yükleme olaylarının nasıl kullanılacağını gösterir. Lütfen örnek excel dosyası‘na bakın
Dosya şifre korumalıdır, önce yanlış bir şifre ile açmayı deniyoruz, ardından nihayetinde FailLoadFile olayında doğru bir şifre kullanarak açıyoruz
