type
  TForm1 = class(TForm)

   //  var
     DataSet : TDataSet

  end;

var
  Form1: TForm1;

implementation

uses Unit2;

{$R *.dfm}

procedure TForm1.DBGrid1DblClick(Sender: TObject);
//var
//DataSet : TDataSet
   begin
 DataSet := DBGrid1.DataSource.DataSet;
 with TForm2.Create(nil)  do begin
    edit1.text :=DataSet.FieldByName(‘客户‘).Asstring;
    ShowModal;
    Free;

end;
  end;
end.
连上面

 procedure TForm2.Button1Click(Sender: TObject);
begin
 with adoquery1 do
begin
close;
sql.clear;
sql.add(‘select * from 销售表 where 客户=‘‘‘+trim(edit1.text)+‘‘‘‘);
open;
end;
end;
