Tutorial 2: Using Report Bands
In this tutorial, we will:
Learn how to use Jasper report bands to create repeating elements in our reports.
Objective
Create reports with repeating elements.
Example:
KEY CONCEPTS
Groups create bands in your report. To create a band, you must create a group.
Sorting, Grouping, and Bands are inextricably tied together.
Report bands will generate every time the field you are grouping by changes.
IF your data is NOT sorted correctly, you'll get "duplicate" bands in your report, each with incomplete data.
Sorting dramatically affects the behavior of the report bands.
IF your data is sorted correctly, the “site band” will print once for each site; the grade level band will print once for each grade level; etc.
