次のサンプルコードは、Spin プロパティを使用します。
GrapeCity.Win.Spread.InputMan.CellType.GcDateTimeCellType datecell = new GrapeCity.Win.Spread.InputMan.CellType.GcDateTimeCellType();
datecell.Spin.AllowSpin = true;
datecell.Spin.IncrementValue = new TimeSpan(2);
fpSpread1.Sheets[0].Cells[0, 0].CellType = datecell;
Dim datecell As New GrapeCity.Win.Spread.InputMan.CellType.GcDateTimeCellType()
datecell.Spin.AllowSpin = True
datecell.Spin.IncrementValue = New TimeSpan(2)
FpSpread1.Sheets(0).Cells(0, 0).CellType = datecell
