Açıklamalar

AutoGenerateColumns özelliği olarak ayarlandığındatrue, her sütun otomatik olarak özelliğini özelliği tarafından belirtilen veri kaynağındaki bir özellik veya veritabanı sütununun DataSource adına ayarlarDataPropertyName. Bu bağlama el ile de gerçekleştirilebilir. Bu, veri kaynağında kullanılabilen özelliklerin veya veritabanı sütunlarının yalnızca bir alt kümesini görüntülemek istediğinizde kullanışlıdır. Bu gibi durumlarda, özelliğini olarak falseayarlayın AutoGenerateColumns ve ardından her DataGridViewColumnbir özelliğin DataPropertyName değerini, görüntülemek istediğiniz veri kaynağındaki özelliklere veya veritabanı sütunlarına ayarlayarak el ile ekleyin.
