lines lost during page-change

rbuser

Hi,

In the past I always used RB with datasets, without any problems.
Now I want to use it with JitPipelines and I get the following problem:

When reaching the end of the page information gets lost ( not finished on
the next page ).
I think it has to be something in my code. I use a report with subreports,
and several Jitpipelines.
I manage the link between the jitpipelines using the
onRecordPositionChange-event.

I use:

Rb7.3 / Delphi5 / JitPipelines

Any suggestion ?

Hi Leon,

Take a look at the following article on how to properly link JIT pipelines
in a master detail relationship. You can also take a look at Demo 139
located in the \RBuilder\Demos\1. Reports\... directory for a working
example of a JIT master detail report.

---------------------------------------------------------
Tech Tip: Define Master/Detail DataPipeline Links in Code
---------------------------------------------------------

Defining a Master/Detail relationship for a JITPipeline or
TextPipeline requires that the detail pipeline have the
following properties defined:

1. MasterDataPipeline

2. MasterFieldLinks


At Delphi design-time you can use the object inspector
and the DataPipeline's FieldLinks editor to define
the master/detail relationship.


The following example illustrates how to define the
master/detail relationship dynamically at run-time.


var
lFieldLink: TppMasterFieldLink;


begin

{define the master/detail pipeline relationship}
JITDetail.MasterDataPipeline := JITMaster;

{create a new field link }
lFieldLink := TppMasterFieldLink.Create(nil);

lFieldLink.DetailDataPipeline := JITDetail;

{assign the detail field name}
lFieldLink.DetailFieldName := 'CustNo';

{assign the master field name}
lFieldLink.MasterFieldName := 'CustNo';


end;

Nico,

Aha, so I need a relational datastructure in my code.
I tried it and it works great.

thanks
