Public Property ColumnSizingArea As ColumnSizingArea
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。
