例

次のコード例は、クラスのメソッドを BorderWidths 使用してセル内の DataGridViewCell 使用可能な描画領域を決定する方法を示しています。 このコード例は、「方法: Windows フォーム DataGridView コントロールのボタン列のボタンを無効にする」で提供されるより大きな例の一部です。

注釈

セルの境界線の既定の幅は 1 ピクセルです。 罫線の幅を変更するには、次 DataGridViewAdvancedCellBorderStyle の値を使用します。

• この値は None 、0 ピクセルの幅を表します。

• 値 OutsetDouble を指定すると InsetDouble 、既定の幅が 1 ピクセル増加します。

さらに、セルの所有行に DividerHeight プロパティが設定されている場合は、四角形の高さが値 DividerHeightによって増加します。 セルの DividerWidth 所有する列にプロパティが設定されている場合、四角形の幅は ゚ の値 DividerWidthだけ増加します。
