public void AddViewport( 
   int sheetIndex,
   int rowViewportIndex,
   int columnViewportIndex
)

Parameters

sheetIndex

Index of sheet to which to add viewports

rowViewportIndex

Index of viewport row to add

columnViewportIndex

Index of viewport column to add

The viewport column and viewport row indexes are zero-based, so the first (leftmost) viewport column and first (top) viewport row both have indexes of 0.

You must add an entire viewport row or viewport column; you cannot add an individual viewport.

Use both indexes to add both a viewport row and viewport column at the same time.

Use -1 for the index if you do not want a set of viewports in that orientation. For example,  AddViewport(0, -1, 3) only adds a viewport column (by the fourth viewport column), but no viewport row is added.
