) 

Visual Basic (Usage)	Copy Code
Dim instance As SpreadView Dim rowViewportIndex As Integer Dim columnViewportIndex As Integer   instance.AddViewport(rowViewportIndex, columnViewportIndex)

public void AddViewport( 
   int rowViewportIndex,
   int columnViewportIndex
)

Parameters

rowViewportIndex

Viewport row index

columnViewportIndex

Viewport column index

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.
