Hi Ronhald,

Tech Tip: Creating a Group in Code
----------------------------------------------------


How can I dynamically create a report group at run-time?


example code:
-------------

uses
ppClass, ppGroup, ppClasUt;


function AddGroupToReport(aBreakName: String; aDataPipeline:
TppDataPipeline; aReport: TppCustomReport);
var
lGroup: TppGroup;
lGroupBand: TppGroupBand;

begin


{add group to report}
lGroup := TppGroup(ppComponentCreate(aReport, TppGroup));

lGroup.Report := aReport;

lGroup.BreakName := aBreakName;
lGroup.DataPipeline := aDataPipeline;

{add group header and footer bands }
lGroupBand := TppGroupBand(ppComponentCreate(aReport,
TppGroupHeaderBand));
lGroupBand.Group := lGroup;

lGroupBand := TppGroupBand(ppComponentCreate(aReport,
TppGroupFooterBand));
lGroupBand.Group := lGroup;


end; {procedure, AddGroupToReport}

the field that lets to group PPreport, How can I Assign this value? Maybe It
's setting something
like.....ppgroupheaderband.groupband.breakname....please help me

Hi Ronhald,

If you want to access groups that have already been created, you will want
to use the TppReport.Groups property. Once you have the group you want to
change, simply use the TppGroup.BreakName property to change the field it
will break on. Where are you trying to make these changes. Be sure you do
so before the report begins generating.
