次のコード例では、 のセル罫 DataGridView 線を調整して、内部セルと左上のヘッダー セルを行ヘッダーと列ヘッダーから二重罫線で区切ります。 このサンプルでは、、AdjustRowHeaderBorderStyle、 メソッド、および AdjustCellBorderStyle プロパティをAdjustColumnHeaderBorderStyleオーバーライドする方法をAdjustedTopLeftHeaderBorderStyle示します。 これらのメンバーは、オブジェクトを使用 DataGridViewAdvancedBorderStyle して個々のセルの罫線を変更します。
