次のサンプルコードは、行の高さをテキストボックスに返します。
FarPoint.Win.Spread.Cell mycell;
mycell = fpSpread1.ActiveSheet.Cells[0, 0];
float cw;
cw = mycell.Row.Height;
mycell.Text = Convert.ToString(cw);
Dim mycell As FarPoint.Win.Spread.Cell
mycell = FpSpread1.ActiveSheet.Cells(0, 0)
Dim size As Single
size = mycell.Row.Height
mycell.Text = size
