Populate an AutoSearchField inList with registers of Data pipeline

rbuser

Hi ,
I need to populate an AutoSearchField inList with registers of one Data
pipeline.
I have tried code below , but it brings only one record (first) ,
how can i bring all records from plGroup??
On Event ReportBeforeAutoSearchDialogCreate

begin

Report.AutoSearchCriteriaByName('plPROD','DSC').searchExpression:=plGroup['G
oupName'];

end;

Thanks....

You would need to traverse all of the records in the DataPipeline.

RAP is not designed to traverse the DataPipeline, it does not contain
run-time type info for DataPipeline methods such as First, Next, etc,

You could either extend the RAP RTTI or code a RAP pass-thru function to
accomplish this.

--------------------------------------------------
Article: Extending RAP
---------------------------------------------------

There are two very simple and powerful techniques to extend the capabilities
of RAP infinitely. These are summarized below and covered in more detail in
the RAP.hlp online help. Demos and tutorials are installed to
RBuilder\Demos\RAP. The tutorial text is located in RAP.hlp.


1. RAP Pass-Through Functions

These are functions that appear in the Language tab of RAP's Code Toolbox.
These functions are written in Delphi and can be called from RAP. RAP's
pass-through function architecture enable's developers to add new built-in
functions to RAP's code toolbox.

2. Extend RAP's RTTI

RAP's Run-time Type information defines what classes and properties can be
accessed via RAP. By default the published properties of any class that is
registered with Delphi's RegisterClass procedure is recognized by RAP. In
addition many of the public properties and methods of ReportBuilder classes
are exposed.
