Hi all,

How can I like to preview a specific record using QReport?
If I use QReport1.Preview, this previews from the beginning of the database. Is there a way to preview
eg. the third record?

Thanks,
Freerider.

Maybe you can set the Filter-Property of the Table you use. Also set the Filtered-property to true.

I you quit the report, set the table back to filtered:=false

A little example :

First be sure to have a Form + Report.
Make sure you linked the DataSet of the report to the same dataset you use on your form (in my example Table1)

Then,when the user clicks on a button on the form, the report is showed, and only the current record should appear on the report, cause my dataset is filtered.

After the report is closed, I clear the filter.



procedure TForm1.Button1Click(Sender: TObject);
begin
  // be sure the DataSet of the reports is linked to the DataSet of my Form.
  Form1.Table1.DisableControls;
  Form1.Table1.Filter := 'Id='+Table1.FieldByName('ID').AsString;
     Form1.Table1.Filtered := True;
     QuickReport2 := TQuickReport2.Create(Self);
  QuickReport2.Previewmodal;
  FreeAndNil(QuickReport2);
  Form1.Table1.Filter := '';
     Form1.Table1.Filtered := False;
  Form1.Table1.EnableControls;
end;

Hi Freerider,
take a look at TQRBand.BeforePrint event. There is PrintBand variable that can be set to false to skip printing this band. Yuo just need to do something like this:

1. TQuickRep.BeforePrint reset some integer variable to zero.
2. TQRBand.BeforePrint

begin
   inc(SomeValue);
   PrintBand := SomeValue > 3;
end;

Or just use a TQuery specifying the exact data you wich to show in your report. You can modifiy at run time the SQL property for more flexibility.
Like:

Query.Close;
Query.SQL.Clear;
Query.SQL.Add('Select * from mytable where myId = :ID');
Query.ParamByName('ID').AsInteger := IdToShow;
Query.Open;
Report.Preview;
