Exceptions

Exception	Description
System.ArgumentOutOfRangeException	Specified sheet index is out of range; must be between 0 and the total number of sheets

Example

fpSpread1.AddViewport(1, 0, 0);

int i;
fpSpread1.SetViewportLeftColumn(1, 1, 5);
i = fpSpread1.GetViewportLeftColumn(1, 1);
textBox1.Text = i.ToString();
