Examples

다음 예제에서는 컨트롤의 MetaTable 개체를 찾는 방법을 보여 줍니다.The following example shows how to find the MetaTable object for a control. 예제에서는 동적 데이터 페이지 템플릿은 AdventureWorksLT 데이터베이스의 ProductDescription 테이블에 대 한 사용자 지정 표시를 제공 \DynamicData\CustomPages\ProductDescriptions 폴더에 복사 됩니다.In the example, the Dynamic Data page templates are copied to the \DynamicData\CustomPages\ProductDescriptions folder to provide a custom display for the ProductDescription table of the AdventureWorksLT database. Insert .aspx 파일 태그는 DetailsView1_DataBound이라는 OnDataBound 이벤트 처리기를 추가 하도록 변경 됩니다 .이 처리기는 FindMetaTable 메서드가 MetaTable 개체를 찾기 위해 호출 됩니다.The Insert.aspx file markup is changed to add an OnDataBound event handler named DetailsView1_DataBound, in which the FindMetaTable method is called to find the MetaTable object.
