Locate in report Script

Hello all,

Is it possible to do a locate in report's script ?
I have a dataset : DS.
I initialize it with that line of code :
DS:=Report.GetDataset('Data');

And tried to do my locate with that code :
if DS.DataSet.Locate('CodeRubrique;mois', VarArrayOf([rub,i])) then
            begin
              ShowMessage('Msg : ' + VartoStr(DS.Value('valeur')));
              ShowMessage('Msg : Valeur n''est pas vide :' + VartoStr(DS.Value('valeur')));
              memo8a.Lines[0] := formatFloat('### ### ##0', DS.Value('valeur'));
              memo8b.Lines[0] := formatFloat('### ### ##0', DS.Value('ssvaleur'));

              DS.NEXT; // Enregistrement suivant
            end

I've tried to make my if statement like in the previous code but getting an error message :
" 'Dataset' is not declared. " (Probably not the exact message because I use it in French and translate it just for you [img]style_emoticons/<#EMO_DIR#>/wink.gif" style="vertical-align:middle" emoid=";)" border="0" alt="wink.gif" /> ) Then I've tried the same without .DataSet :[/img]
if DS.Locate('CodeRubrique;mois', VarArrayOf([rub,i])) then

I get the same error message for 'Locate'.



FYI, here is the entire code of the report :
// Parcours de la liste des champs d'une query Delphi
// Ne pas affecter de Dataset ?  la MasterDataBand
procedure Page1OnManualBuild(Sender: TfrxComponent);                                               
var DS: TfrxDataSet;
    i, lig, col : integer;
    rub : string;
begin
  //Chargement du DataSet en provenance de Delphi
  DS.First;      
end;

procedure MasterData1OnBeforePrint(Sender: TfrxComponent);
begin

end;

procedure DetailData1OnBeforePrint(Sender: TfrxComponent);
var DS: TfrxDataSet;
    i, lig, col : integer;
    rub : string;                                  
begin

    I've made a mistake on the locate's code part. I've tried to make the locate with these 2 lines of code (one after the other) :
    if DS.Locate('CodeRubrique;mois', VarArrayOf([rub,i], 0)) then
    ---------------------------------------------------------------------------------------------
    if DS.DataSet.Locate('CodeRubrique;mois', VarArrayOf([rub,i], 0)) then
    
  • For those interested :


    procedure chSDRMsupportOnBeforePrint(Sender: TfrxComponent);

    var sdrm:TfrxDBDataset;                                            

    begin

     sdrm:=TfrxDBDataset(Report.GetDataset('frxSDRM'));

     sdrm.Open;                       

     sdrm.Locate('uniqueobjectid',<frxMVEN."uniqueobjectid">,0);                                                                                                

    end;
