The header band contains heading information that is displayed at the top of every screen or page. The presentation style determines the contents of the header band:
If the presentation style is Tabular or Grid, the headings defined for the columns in the Database painter display in the header band and the columns display on a single line across the detail band
If the presentation style is Freeform, the header band is empty and labels display in the detail band next to each column
You can specify additional heading information (such as a date) in the header band, and you can include pictures and color to enhance the appearance of the band.
Displaying the current date To include the current date in the header, you place a computed field that uses the Today DataWindow expression function in the header band. For information, see “Adding computed fields to a DataWindow object”.
