설명

DataGridViewImageColumn 클래스는 이미지를 표시 하는 셀을 논리적으로 호스트 하는 데 사용 되는 DataGridViewColumn 클래스의 특수 한 형식입니다.The DataGridViewImageColumn class is a specialized type of the DataGridViewColumn class used to logically host cells that display images. A DataGridViewImageColumn 에 연결 된 DataGridViewImageCell 에서 모든 DataGridViewRow 과 교차 하는 합니다.A DataGridViewImageColumn has an associated DataGridViewImageCell in every DataGridViewRow that intersects it. 각 셀은 DataGridViewImageCell.ValueIsIcon 속성의 값에 따라 Image 또는 Icon를 포함할 수 있습니다.Each cell is capable of containing an Image or an Icon, depending on the value of the DataGridViewImageCell.ValueIsIcon property. 아이콘을 표시 하는 것은 투명도 사용 하 여 이미지를 수용할 수 있도록 하는 데 유용 합니다.Displaying icons is useful to accommodate images with transparency.

기본적으로 빈 셀 기본 오류 그래픽을 표시 합니다.By default, empty cells display a default error graphic. null 또는 DBNull.Value와 동일한 셀 값에 대해이 그래픽이 나타나지 않도록 하려면 DefaultCellStyle 속성에 의해 반환 되는 셀 스타일 개체의 DataGridViewCellStyle.NullValue 속성을 컨트롤에 행을 추가 하기 전에 null로 설정 합니다.To prevent this graphic from appearing for cell values equal to null or DBNull.Value, set the DataGridViewCellStyle.NullValue property of the cell style object returned by the DefaultCellStyle property to null before adding rows to the control. 그러나 새 레코드의 행을 적용 되지 않습니다.This does not affect the row for new records, however. 컨트롤 AllowUserToAddRows 속성 값이 true될 때 새 레코드의 행에 오류 그래픽이 표시 되지 않게 하려면 컨트롤 RowsAdded 이벤트에 대 한 처리기에서 셀 값을 null로 명시적으로 설정 하거나 CellTemplate를 반환 하는 재정의 된 DataGridViewImageCell속성을 사용 하 여 열 DefaultNewRowValue 속성을 null파생 형식의 인스턴스로 설정 해야 합니다.To prevent the error graphic from appearing in the row for new records when the control AllowUserToAddRows property value is true, you must also either explicitly set the cell value to null in a handler for the control RowsAdded event or set the column CellTemplate property to an instance of a DataGridViewImageCell-derived type with an overridden DefaultNewRowValue property that returns null.

이 열 형식에 대 한 기본 정렬 모드 NotSortable합니다.The default sort mode for this column type is NotSortable.

상속자 참고

파생 하는 경우 DataGridViewImageColumn 파생된 클래스에 새 속성 추가 재정의 해야 합니다 Clone() 복제 작업 중 새 속성을 복사 하는 방법입니다.When you derive from DataGridViewImageColumn and add new properties to the derived class, be sure to override the Clone() method to copy the new properties during cloning operations. 또한 기본 클래스를 호출 해야 Clone() 메서드는 기본 클래스의 속성이 새로운 셀에 복사 되도록 합니다.You should also call the base class's Clone() method so that the properties of the base class are copied to the new cell.
