'Usage
 
Dim instance As FpSpread
Dim rowViewportIndex As Integer
Dim columnViewportIndex As Integer
 
instance.AddViewport(rowViewportIndex, columnViewportIndex)

public void AddViewport( 
   int rowViewportIndex,
   int columnViewportIndex
)

Parameters

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(-1, 3) only adds a viewport column (by the fourth viewport column), but no viewport row is added.
