 public SheetViewState ViewState{ get; set; }

Public Property ViewState() As SheetViewState

//--- Get ViewState
Worksheet.SheetViewState state = ws.ViewState;

//--- Set ViewState
ws.ViewState = Worksheet.SheetViewState.PageBreak;

'--- Get ViewState
Dim state As Worksheet.SheetViewState = ws.ViewState

'--- Set ViewState
ws.ViewState = Worksheet.SheetViewState.PageBreak

Attempting to set ViewState to PageLayout in an Excel 2003 or earlier workbook will throw an ArgumentException.

The viewing mode may be any of the values defined by SheetViewState. By default, worksheets are in Normal mode.

Note that only Excel 2007 or later workbooks support PageLayout mode.

Setting this property to null will set the mode to Normal.
