Örnekler

Aşağıdaki kod örneği, bir hücredeki BorderWidths kullanılabilir çizim alanını belirlemek için sınıfının yönteminin DataGridViewCell nasıl kullanılacağını gösterir. Bu kod örneği, Nasıl yapılır: Windows Forms DataGridView Denetimindeki Düğme Sütunundaki Düğmeleri Devre Dışı Bırakma bölümünde sağlanan daha büyük bir örneğin bir parçasıdır.

Açıklamalar

Hücre kenarlarının varsayılan genişliği bir pikseldir. Kenarlık genişliğini değiştirmek için aşağıdaki DataGridViewAdvancedCellBorderStyle değerleri kullanın:

Ayrıca, özelliği hücrenin DividerHeight sahip olduğu satır için ayarlanırsa dikdörtgenin yüksekliği değeriyle DividerHeightartırılır. DividerWidth Özelliği hücrenin sahip olduğu sütun için ayarlanırsa, dikdörtgenin genişliği değeriyle DividerWidthartırılır.

Şunlara uygulanır
