ColumnSizingArea プロパティ

グリッドのインターフェイスのどの部分を使用して列のサイズを変更するかを決定する値を取得または設定します。

'宣言
 
Public Property ColumnSizingArea As ColumnSizingArea

C#

public ColumnSizingArea ColumnSizingArea {get; set;}

解説

列のサイズ変更が有効な場合 (AllowColSizing プロパティによって設定します) 、ユーザーはマウスを使用して列のサイズを変更できます。サイズ変更の際は常に、列の右端をクリックしてドラッグします。ColumnSizingArea プロパティは、列のサイズ変更時に列のどの部分がマウス ポインターに反応するかを指定します。列ヘッダーのみ、列セルの境界線のみ、その両方のいずれかを選択できます。マウス ポインターを列のアクティブな領域の上に置くと、カーソルがサイズ変更カーソルに変わります。
