Açıklamalar

nesnesinin Text düğmelerinde ButtonColumn görüntülenen resim yazısını belirtmek veya belirlemek için özelliğini kullanın.

Not

Özelliği ayarlarsanız Text , içindeki ButtonColumn tüm düğmeler aynı açıklamalı alt yazıyı paylaşır.

Alternatif olarak, veri kaynağındaki ButtonColumn bir alana bağlayabilirsiniz. Bu, belirtilen alandaki değerleri kullanarak sütundaki düğmeler için farklı resim yazıları görüntülemenizi sağlar. DataTextField özelliğini bir veri kaynağındaki bir alana bağlamak ButtonColumn için ayarlayın.

Bu özelliğin değeri görünüm durumunda depolanır.

Bu özelliğin değeri ayarlandığında, tasarımcı aracı kullanılarak otomatik olarak bir kaynak dosyasına kaydedilebilir. Daha fazla bilgi için bkz LocalizableAttribute . ve Genelleştirme ve Yerelleştirme.
