Örnekler

Aşağıdaki kod örneği ve ListView denetimlerinin PictureBox kullanımını gösterir. PictureBox, sırasıyla ve sabit listeleri kullanılarak BorderStyle ve SizeModePictureBoxSizeMode özellikleri ayarlanarak BorderStyle başlatılır. ListView, Örnek Resimler dizinindeki resimlerle doldurulur. yöntemiListView.GetItemAt, bir öğenin seçilip seçilmediğini belirlemek için denetimin ListView olayını işlerken MouseDown kullanılır. Bir öğe seçilirse, olay işleyicisi özelliğini ayarlayarak Image seçili dosyayı görüntüler. Örnek, C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures dizininde bulunan JPG dosyalarınız olmasını gerektirir. Bu örneği çalıştırmak için, kodu bir forma yapıştırın ve formun InitializePictureBox oluşturucusunda veya Load olay işleme yönteminde ve PopulateListView yöntemlerini çağırın. Tüm olayların olay işleme yöntemleriyle ilişkilendirildiğinden emin olun.
