Örnekler

Aşağıdaki kod örneği, bu özelliğin öncelikli olarak görüntülenmek üzere tasarlanmış bir DataGridView denetimde kullanımını gösterir. Bu örnekte, denetimin görsel görünümü çeşitli şekillerde özelleştirilir ve denetim sınırlı etkileşim için yapılandırılır. Bu örnek, sınıfa genel bakış bölümünde DataGridViewCellStyle bulunan daha büyük bir örneğin parçasıdır.
