DataControlRowType 열거형

정의

DetailsView 또는 GridView 컨트롤과 같은 데이터 컨트롤에 있는 행의 기능을 지정합니다.

public enum class DataControlRowType
public enum DataControlRowType
type DataControlRowType = 
Public Enum DataControlRowType
상속
DataControlRowType

필드

DataRow 2

데이터 컨트롤의 데이터 행입니다. DataRow 행만 데이터 바인딩할 수 있습니다.

EmptyDataRow 5

데이터 바인딩된 컨트롤의 빈 행입니다. 데이터 바인딩된 컨트롤에 표시할 레코드가 없고 EmptyDataTemplate 템플릿이 null이 아니면 빈 행이 표시됩니다.

1

데이터 컨트롤의 바닥글 행입니다. 바닥글 행은 데이터 바인딩할 수 없습니다.

Header 0

데이터 컨트롤의 머리글 행입니다. 머리글 행은 데이터 바인딩할 수 없습니다.

Pager 4

페이저 단추 또는 페이저 컨트롤을 표시하는 행입니다. 페이저 행은 데이터 바인딩할 수 없습니다.

Separator 3

행 구분선입니다. 행 구분선은 데이터 바인딩할 수 없습니다.

예제

다음 코드 예제를 사용 하는 방법에 설명 합니다 DataControlRowType 작업할 때 행의 형식을 확인 하는 열거형을 GridView 컨트롤입니다. AuthorsGridView_RowCreated 메서드를 사용 하면를 CommandArgument 의 속성을 LinkButton 컨트롤은 모든 데이터 행에 대 한 고유를 GridView 컨트롤 있도록 때 행의 LinkButton 컨트롤을 클릭 하면, 올바르게 식별할 수 있습니다.

설명

DataControlRowType 열거형 데이터 컨트롤에 있는 행의 함수를 식별 합니다. 사용 되는 DetailsViewGridView 데이터를 표시 하는 행 및 다른 사용자를 표시 하는 행을 구분 하기 위해 컨트롤 인터페이스 (UI) 요소를 머리글 행, 행 구분 기호, 페이저 단추 등입니다.

사용할 수는 DataControlRowType 의 형식을 식별 하는 열거형을 GridViewRow 또는 DetailsViewRow 전체를 열거 하는 경우 개체를 GridViewRowCollection 또는 DetailsViewRowCollection 컬렉션입니다. 행을 만드는 데이터 컨트롤을 작성 하는 경우 사용할 수 있습니다는 DataControlRowType 컨트롤의 다른 행의 기능을 식별 하는 열거형입니다.
