Exceptions

Exception	Description
System.ArgumentOutOfRangeException	Specified sheet index is not valid; must be between 0 and total number of sheets.

The viewport column index is zero-based, so the first (leftmost) viewport column has an index of 0.

Example

FarPoint.Win.Spread.SpreadView sv;
int i;
sv = fpSpread1.GetRootWorkbook();
sv.AddViewport(0, 0);
sv.SetViewportLeftColumn(0, 5);
i = sv.GetViewportLeftColumn(0, 0);
MessageBox.Show("The left-most column of the viewport is " + i.ToString());

Dim sv As FarPoint.Win.Spread.SpreadView
