Each footer or button label may be left or right adjusted or centered within the column boundaries (see Footer.TextHAlign and Footer.TextVAlign). Column footers can contain graphics (see Footer.Image). Each column footer can contain single or multiple lines of text (see Footer.Text and Footers.Multiline) and a graphic.
The built-in column footers support text and one graphic for each column. All graphics must be the same height and width for all columns.

If a user clicks on a column footer, the application receives an ItemClick or ItemDblClick event with an AreaType of constSftTreeColumnFooter.
Only one column footer button can be in the pressed position at any one time (see Footers.Pressed).
