The form/datamodule upon which the TppReport component resides should be the
Owner of the report, bands, labels, etc. (This is Delphi standard for
TComponent descendants).
The Owner is passed to the constructor. (This is… -
This feature is working as designed. The RAP global OnCreate should only
fire a single time. Firing multiple times was a bug reported long long ago
and caused memory leaks and broken code.

Try using the DBDemos data to create a simple example project that
demonstrates the issue. Send in zip format to support@digital-metaphors.com
and we can research it here.

The timing of RAP Global OnCreate and OnInitializeParameters is almost
identical. See ppReport.pas, the method TppReport.InitializeParameters. The
OnCreate is fired, followed immediately by OnInitializeParameters.

Memo.Lines is of type TStrings.
So the simplest syntax is
myMemo2.Lines.Text := myMemo1.Lines.Text;
The above will work for Delphi code and RAP code.
Within a report or childreport you can reference …
This is a DADE issue, not a RAP issue.

Currently the RAP source is stored as plain text, there is no parsing, no
concept of objects. Therefore such a change would be a big departure from
the current implementation.

Data-aware controls such as DBText are bound using the DataField property -
which is a field name. To be more user friendly, the Designer displays the
FieldAliases in the format toolbar.

I'm not clear on the question, but thought I would add that the Report and
ChildReport classes have a NoDataBehaviors property that can be used to
control what happens when the DataPipeline is empty.

A better solution to your issue is to keep the RAP event-handler code short

The main report has a Report.Parameters[ ] property
ChildReports (ie. subreport.Report) do /not/ have a Parameters property.

Starting with RB 11, you can define Report.Parameters[ ] that optionally
have AutoSearchSettings and LookupSettings. You can also use the Query
Designer to bind a search condition to a Parameter. For the SQL to generate

There information in the Developers Guide tutorials on extending RAP with
additional RTTI and custom functions. Working demos and tutorials are also
installed with the product.
Going I recommend updating to R…RB 12 introduces support for using the FieldAlias or the FieldName
Value := DataPipeline['FieldAlias or FieldName'];
Prior to RB 12, you would need extend RAP with a custom pass-thru function
as you propose.
See the code example I posted earlier, at the bottom there is this line...
// show autosearch dialog on toolbar
ppReport1.ShowAutoSearchDialog := True;

You can write some code to handle that type of search. Use the
Report.BeforeOpenDataPipelines event and the TdaSQLBuilder class to modify
the SQLText.
Here is a simple example:

I don't understand the question.
RB 9 introduced the Report.OnInitializeParameters event, prior to that the
event did not exist.
The Report.OnInitializeParameters event is working as designed.
From the RBuilder…With RB 12 you can bind a report parameter to multiple queries without
writing any code.
