예제

다음 예제에서 열 고정 "를 선택 하면 열을 고정 하는 방법을 보여 줍니다는 ContextMenu합니다.The following example shows how to freeze a column when "Freeze Column" is selected from the ContextMenu. 열은 고정된 된 열에 포함 하기 위해 왼쪽으로 이동 됩니다.Columns are moved to the left in order to be included in the frozen columns.

<!--Defines the handlers for when the FreezeColumnCommand is executed-->

설명

IsFrozen 열 고정을 사용할 수 없습니다.IsFrozen cannot be used to freeze a column. 대신, 설정 된 FrozenColumnCount 속성입니다.Instead, set the FrozenColumnCount property. 최대 지정 된 열 맨 왼쪽 열은 FrozenColumnCount 번호 위치에 고정 됩니다.The leftmost columns up to the column that is specified by the FrozenColumnCount number will freeze in place.
