How do you can the default paper size to something other than A4?
I understand
Worksheet.PageSetup.PaperSize = PaperSizeType.PaperLetter
but this is not available in all versions of the product. I am not trying to change it dynamically, only the default. A4 is not particularly relevant to us in the States.
What’s the default paper size you want to set? You can use a designer file and use Aspose.Excel to import it. The default paper size in your designer file will be imported.
