Where does IFooter live in the IronXL API?

IFooter is an interface in the IronXL.Layout namespace, shipped in IronXL.dll. It extends IHeaderFooter and is returned by the WorkSheet.Footer property.

What is the difference between IFooter and IHeader in IronXL?

Both extend IHeaderFooter and share the same inherited Left, Center, and Right text properties with no added members. WorkSheet.Footer returns an IFooter for the bottom of the page, and WorkSheet.Header returns an IHeader for the top; the type only indicates which band is being edited.

Syntax

public interface IFooter : IHeaderFooter

When a printed worksheet needs text along the bottom of every page, a page number, a confidentiality note, or a filename, IFooter is the contract that holds it. It is what a worksheet returns specifically for the bottom-of-page band, the counterpart to the header that prints across the top. A developer assigns text to its three positioned zones so a printed or exported spreadsheet carries a consistent footer without editing the file by hand in Excel.

A developer obtains an IFooter from WorkSheet.Footer; there is no constructor, and the footer belongs to its worksheet. IFooter extends IHeaderFooter and declares no members of its own, so its editable surface is entirely inherited: the Left, Center, and Right properties, each a readable and writable string, hold the text for the left, center, and right zones of the footer band. The matching IHeader, returned by WorkSheet.Header, shares the same inherited surface; the two types differ only in which page band they target. Set the zones a layout needs and save the workbook to apply them to print output.

IFooter footer = sheet.Footer;
footer.Center = "Page &P of &N";
footer.Right = "Confidential";

The Excel print setup example configures a sheet for printing, where footer text prints on each page, and the IHeaderFooter reference documents the inherited Left, Center, and Right zones.
