Create some fields in runtime

J.C. Arteaga

Hi, I have a report with a Masterdata band and some fields in it. It works fine, however I create some field in runtime (based on the user preferences). I use the following code to create the frxMemoView:

  frmTitle,frmField : TfrxMemoView;
  frbTitle,frbMaster: TfrxBand;
  i : smallint;
  fLeft, fWidth : Double;
begin
  fLeft := 12;
  fWidth := 1.20;
  with NData,frxReporte do
  begin
    frbMaster := FindObject('frbMasterData') as TfrxMasterData;
    frbTitle := FindObject('frbColumnHeader') as TfrxColumnHeader;
    for i := cbMes1.ItemIndex to cbMes2.ItemIndex do
    begin
      frmTitle := TfrxMemoView.Create(frbTitle);
      frmtitle.CreateUniqueName;
      frmTitle.Text := cbMes1.Properties.Items[i];
      frmTitle.Font.Name :='Tahoma';
      frmTitle.Font.Size := 8;
      frmTitle.Font.Style := [fsBold];
      frmtitle.HAlign := haCenter;
      frmTitle.SetBounds(fLeft,0,fWidth,1.10);
      with TfrxMemoView.Create(frbMaster) do
      begin
        CreateUniqueName;
        SetBounds(fLeft,0,fWidth,0.5);
        Autowidth := true;
        DataSet := fdsDatos;
        DataField := cbMes1.Properties.Items[i];
        HAlign := haRight;
        Font.Size := 8;
        Font.Name := 'Tahoma';
        Frame.Typ := [ftLeft];
      end;
      fLeft := fLeft + fWidth;
    end;
  end;

But this code don't work, I can't see the objects created in the report.

Thank you in advance for your help

your problem lies in the declartion of your variables.
frbTitle,frbMaster: TfrxBand;
the variable must be of the correct type.
ie
frbmaster should be of type tfrxmasterdata;

Thanks its work fine.

Another issue is the position of the Objects. For example in designtime the left property has the value 8.1, but in runtime the same property has another value. Why? How can i set the correct values to positioning the object .(I am using the Setbounds method)

Thanks in advance.
