Data Tree

All properties of the objects can be set in the Object inspector window, which can be displayed or hidden in the “View>Toolbars...” menu command.

The Data Tree window consists from four tabs:

- Data

- Variables

- Functions

- Classes

You can dragged and dropped to the desktop all data available in the Data tree 

Data

On tab data you can find all datasets and their datafields.

Variables

On tab data you can find variables which are of two types

1: System variables - these variable are provided by FastReport

2: User defined variables - these variables are defined by user. We will meet them later

System variables are:
 

• Date

• Time

• Line - Line number in the table. It is considered for each group in the table separately.

• Line# - Line number in the table. It shall be counted from the beginning of the report.

• Page - The page number that resets at the beginning of a new group if its header (GroupHeader) properties ResetPageNumbers and StartNewPage are set to True.

• Page# - Page number. It is counted from the beginning of the report.

• TotalPages - The page number that resets at the beginning of a new group if its header (GroupHeader) properties ResetPageNumbers and StartNewPage are set to True.

• TotalPages# - Number of pages on the report. It is counted from the beginning of the report.

System variables Page and TotalPages get values only when the report is generated to the end. If we want to use them in the script, n the “View>Toolbars...” menu command on the General tab select the DoublePass setting.
