Thank you for your kindness again !
Another curious (stupid) question, why “Worksheet.Cells.ApplyStyle” instead of “Worksheet.ApplyStyle” ?
Thanks for your posting and using Aspose.Cells.
Workbook.DefaultStyle will apply style to entire workbook. So if you will add a new worksheet inside the workbook, it will follow the default style of the workbook.
Worksheet.Cells.ApplyStyle() will apply style to current entire worksheet, if you will add a new worksheet inside the workbook, it will not be affected with the style applied to previous worksheet.
Worksheet.ApplyStyle() method does not exist.
Thank you for your helpful elaboration of the API !
