The report generator will specify a reference to the data band so that it knows how many times the data band should be printed. There are several ways to do this. First, you can use the databand editor. Double-click the data band to call the editor. You can also call the editor from the context menu. Below is an example of this menu.

You can also call the editor using the databand's DataSource property.

Each category is one data connection with data in the data dictionary. The figure below shows the data in the databand editor.
