grouping objects on a band

rbuser

In Ace, the objects on a band are 'children' of that band, such that I can
set the font properties of the band and these properties get applied these
'child' objects on the band. Is there a way to do something similar in RB?

Hi Rob,

In ReportBuilder, each object belongs to a band by defining its "Band"
property. This allows you to loop through each object in a certain band and
change its properties any way you like. Check out the article below for an
example of how this can be done. Note that you do not necessarily need to
loop through all the objects in your report, you can limit the loop to a
single band.

Tech Tip: Loop Thru All Objects in a Report
---------------------------------------------

A ReportBuilder report is composed of a set
of components. The basic structure is

Reports.Bands[].Objects[]

The bands and objects within the report can
be accessed directly by object name or
via the Bands and Objects array properties.

Below is an example of using the Bands and
Objects array properties to change the font for
all objects on a report.


uses
ppClass;


procedure AssignFontToReport(aFont: TFont; aReport: TppCustomReport);
var
liBand: Integer;
liObject: Integer;
lObject: TppComponent;

begin

for liBand := 0 to aReport.BandCount-1 do

for liObject := 0 to aReport.Bands[liBand].ObjectCount-1 do
begin
lObject := aReport.Bands[liBand].Objects[liObject];

if lObject.HasFont then
lObject.Font := aFont;

end;

end;
