Recently, I meet a problem that I need to insert header and footer in excel with C#, I use the following code:
Worksheet sheet = workbook.Worksheets[0];
sheet.PageSetup.FullHeaderString = "E-iceblue";
sheet.PageSetup.IsPrintHeadings = true;
sheet.Visibility = WorksheetVisibility.Visible;
sheet.PageSetup.LeftFooter = "everlasting";
But when I launch it, the header and footer do not appear in the excel table, after I click insert header and footer button, it shows, When I put it in a view and print it out, it shows header and footer.What is the problem?
Can anybody help me?
I use the OS and Spire.XLS.
