 override System::Web::UI::WebControls::Style ^ CreateControlStyle();

protected override System.Web.UI.WebControls.Style CreateControlStyle ();

override this.CreateControlStyle : unit -> System.Web.UI.WebControls.Style

Protected Overrides Function CreateControlStyle () As Style

Style

컨트롤에 대한 기본 스타일 속성이 들어 있는 TableStyle입니다.

예제

다음 코드 예제에서는 컨트롤에 셀 간격이 없는 가로 눈금선을 항상 표시하도록 사용자 지정 서버 컨트롤에서 메서드를 재정 CreateControlStyle 의 DataList 하는 방법을 보여 줍니다.
