次のサンプルコードは、FocusRectangleプロパティを設定します。
FarPoint.Win.Spread.CellType.CheckBoxCellType checkcell = new FarPoint.Win.Spread.CellType.CheckBoxCellType();
checkcell.FocusRectangle = FarPoint.Win.FocusRectangle.Show;
fpSpread1.Sheets[0].Cells[1, 1].CellType = checkcell;
Dim checkcell As New FarPoint.Win.Spread.CellType.CheckBoxCellType
checkcell.FocusRectangle = FarPoint.Win.FocusRectangle.Show
FpSpread1.Sheets(0).Cells(1, 1).CellType = checkcell
