Bands

There are many bands in Report Designer, each with its own unique capabilities. All bands can be categorized into one of two types:

• Standard Bands
• Cross Bands

Standard Bands

Standard bands are rendered from top to bottom. They are typically placed directly on a page or can be placed on a panel. Standard bands are the fundamental elements of any report. Please refer to the list below to see all the standard bands.

Icon	Band Name	Description
	Report Title	This band is printed in the beginning of a report
	Report Summary	This band is printed in the end of a report
	Page Header	This band is printed on the top of each page
	Page Footer	This band is printed on the bottom of each page
	Group Header	This band is printed in the beginning of a group
	Group Footer	This band is printed in the end of a group
	Header	This band is printed before data
	Footer	This band is printed after data
	Column Header	This band is printed before a column is output
	Column Footer	This band is printed after a column is output
	Data	This band is printed as many times as there are rows in the data source
	Hierarchical Data	This band is printed as many times as there are rows in the data source. Data items are output as a tree
	Child	This band is printed only once, after the band beneath which it is placed
	Empty Data	Fills the free space at the bottom of a page
	Overlay	This band is printed on the background of a page. It does not have effect on other bands.

To enhance the clarity and improve the understanding of report structures, each type of band is assigned a specific color in the report template.

Cross Bands

Cross bands are rendered from left to right. They are usually placed on standard bands. There is one special category of band called the Child band, which, although it is a standard band, is commonly used to extend a Data band.

Cross-bands must be placed on a standard band, and thus cannot be directly placed on a page or a container. They are used to enable the rendering of complex cross-reports. Cross bands occupy the full height of their parent component, so it is not recommended to place them directly on the page. If the band does not fit on one page, it is not wrapped, but a new page segment is added.

Icon	Band Name	Description
	Cross-Group Header	This band is printed in the beginning of a group
	Cross-Group Footer	This band is printed in the end of a group
	Cross-Header	This band is printed before data
	Cross-Footer	This band is printed after data
	Cross-Data	This band is printed as many times as there are rows in the data source

Unlike simple bands, the cross-bands header is displayed at the bottom of a band.
