This example demonstrates how to control the visibility of the worksheet gridlines. To do this, use the WorksheetView.ShowGridlines property of the worksheet view object that is accessed via the Worksheet.ActiveView property.
To specify whether the worksheet gridlines should be printed, use the WorksheetPrintOptions.PrintGridlines property of the object accessed via Worksheet.PrintOptions. Refer to the How to: Specify Print Settings document for details on how to specify print options for a worksheet.
