I'm having trouble getting the contents of a table created at runtime to show in a DBGrid (called EstimateGrid). The table is being created and modified successfully, but not showing at all in the grid. Extract of code follows. Please help. Thanks.

DataSource2 := TDataSource.Create(self);
DataSource2.Dataset := Table;
DataSource2.Enabled :=True;
EstimateGrid.DataSource := DataSource2;
EstimateGrid.Enabled := True;

Hi cavalry,

Did a little test, but everything seems to work.

You 're sure the table is active?

ps. Don't forget to free your create datasource!!!!!

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  Grids, DBGrids, Db, DBTables;

type
  TForm1 = class(TForm)
    Table1: TTable;
    DBGrid1: TDBGrid;
    procedure FormCreate(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
  private
    { Private declarations }
    DataSource2 : TDataSource;
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.FormCreate(Sender: TObject);
begin
DataSource2 := TDataSource.Create(self);
DataSource2.Dataset := Table1;
DataSource2.Enabled :=True;
DBGrid1.DataSource := DataSource2;
DBGrid1.Enabled := True;
Table1.Open;  <----------- !
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
 DataSource2.Free;
end;

end.

Regards, Zif.
