예제

다음 예제에서는 지정 된 열 이름에 대 한 텍스트 상자 컨트롤을 찾는 방법을 보여 줍니다.The following example shows how to find the text box control for a specified column name. 예를 들어, Dynamic Data 페이지 템플릿이 AdventureWorksLT 데이터베이스의 제품 설명 테이블에 대 한 사용자 지정 표시를 제공 하기 위해 \DynamicData\CustomPages\ProductDescriptions 폴더에 복사 됩니다.In 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. OnDataBound DetailsView1_DataBound FindDataSourceControl 텍스트 상자 컨트롤을 찾기 위해 메서드를 호출 하는 이라는 이벤트 처리기를 추가 하도록 .aspx 파일 태그를 변경 합니다.The Insert.aspx file markup is changed to add an OnDataBound event handler named DetailsView1_DataBound, in which the FindDataSourceControl method is called to find a text box control.
