DataGridTextBoxColumn.Edit 메서드

정의

편집할 셀을 준비합니다.

매개 변수

source
CurrencyManager

열이 속하는 CurrencyManager 컨트롤의 DataGrid입니다.

rowNum
Int32

편집되고 있는 이 열의 행 번호입니다.

bounds
Rectangle

컨트롤이 위치할 경계 Rectangle입니다.

readOnly
Boolean

열이 읽기 전용인지 여부를 나타내는 값입니다. 값이 읽기 전용이면 true이고, 그렇지 않으면 false입니다.

instantTextdisplayText
String

컨트롤에 표시할 텍스트입니다.

cellIsVisible
Boolean

셀을 표시할지 여부를 나타내는 값입니다. 셀이 표시되면 true이고, 그렇지 않으면 false입니다.

예제

다음 예제에서는 메서드를 Edit 사용하여 컨트롤에서 클릭한 셀 DataGrid 의 텍스트를 변경합니다.

설명

Edit 편집할 셀의 위치에 있는 표에 컨트롤이 있는 사이트 TextBox 입니다. 편집 작업을 시작하려고 할 때 클래스의 BeginEdit 메서드에서 메서드를 호출 DataGrid 합니다.
