Açıklamalar

BorderColor Web Sunucusu denetiminin kenarlık rengini belirtmek için özelliğini kullanın. Bu özellik bir Color nesne kullanılarak ayarlanır.

Not

BorderColor özelliği yalnızca belirli denetimler için işlenir. Örneğin, Table, Panel, , DataGridCalendarve ValidationSummary denetimleri bu özelliği işler. Ayrıca, özellikleri olarak RepeatLayout.Flowayarlıysa RepeatLayout.TableRepeatLayout , RadioButtonListve DataList denetimleri için CheckBoxListde çalışır. Ancak, HTML 3.2 standardının parçası olmayan özniteliği olarak bordercolor işlenir. bordercolor Özniteliği Microsoft Internet Explorer sürüm 3.0 veya üzeri için çalışır, ancak diğer tarayıcıların çoğunda çalışmaz.

BorderColor Özellik ayarlanmadığında tarayıcı varsayılan kenarlık rengini kullanır. Varsayılan renk düzenini belirlemek için tarayıcınıza bakın.

Şunlara uygulanır
