Örnekler

Aşağıdaki kod örneğinde bu özelliğin kullanımı gösterilmektedir. Bu örnek, How to: Customize the Appearance of Rows in the Windows Forms DataGridView Control (DataGridView Denetimindeki Satırların Görünümünü Özelleştirme) bölümünde bulunan daha büyük bir örneğin parçasıdır.

// Paints the custom selection background for selected rows.

    // with the custom selection background.
