Delete Records from DBGrid

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    DataSource1: TDataSource;
    DBGrid1: TDBGrid;
    Table1: TTable;
    procedure DBGrid1KeyDown(Sender: TObject; var Key: Word;
      Shift: TShiftState);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.DBGrid1KeyDown(Sender: TObject; var Key: Word;
  Shift: TShiftState);
begin
 If Key = VK_Delete then
 begin
    if MessageDlg('Are you sure you want to delete this record ?',
    mtConfirmation, [mbYes, mbNo], 0) = mrYes then
  begin
    Table1.Delete;
    MessageDlg('Record has been deleted.', mtInformation,
      [mbOk], 0);

  end;
 end;
end;

end.

But please, prevent the users errors, adding this code in the beforeDelete event of your Ttable:

if Application.MessageBox('¿Are you sure....?','Atención',mb_OkCancel + mb_IconQuestion)= idcancel then
abort;

I think that dgConfirmDelete (Options) is set to False, to avoid the not customize message.

Best Regards.
