Tech Tip: How to Programmatically Load Reports that were Saved
using the Report Explorer
---------------------------------------------------------------

1. The ReportExplorer has a run-time interface you can use to load
reports using the ReportExplorer.LoadReport method. You can use this
method without actually 'showing' the report explorer form. (See the
online help topic for TppReportExplorer.)

2. If you want use Report.Template.LoadFromDatabase, RB will locate the
report stored in the database table based upon the NameField value only.
However, for the rb_item table you really need Folder_Id, Name to locate
a record uniquely.

To override this default behavior, you can assign an event-handler to
the Report.Template.OnLocateRecord event.

example:

TmyForm = class(TForm)
private
function ReportLocateRecordEvent(Sender: TObject; const
aReportName: String): Boolean;

end;

procedure TmyForm.FormCreate(Sender, TObject);
begin
{assign the event handler}
FReport.Template.OnLocateRecord := ReportLocateRecordEvent;
end;


function TmyForm.ReportLocateRecordEvent(Sender: TObject; const
aReportName: String): Boolean;
begin
{add logic here to locate the record and return True if it is found}

Result := myLocateReportFunction(FFolderid, aReportname);

end;

Hi Marcelo,

The myLocateReportFunction is a method you create in order to locate the
record and return True if it is found. For instance, you would add logic to
traverse through each record in the FolderID and Name fields in your Items
table and if you find a match to the parameters sent in, return True.
