[转]Delphi下拉列表框

有表：Id,Name 想在下拉列表框中显示Name,选择后可获得Id值，下拉列表框动态生成，个数不定。

//载入 procedure TForm1.FormCreate(Sender: TObject); var PID: PInteger; i: integer; begin with ComboBox1 do for i := 0 to 20 do begin new(PID); PID^ := i; items.AddObject('item' + inttostr(i), TObject(PID)); end; end; //使用 procedure TForm1.ComboBox1Change(Sender: TObject); var ID: integer; begin ID := PInteger(ComboBox1.Items.Objects[ComboBox1.ItemIndex])^; showmessage(ComboBox1.Items[ComboBox1.ItemIndex] + #13#10 + inttostr(ID)); end; //删除 procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction); var i: integer; begin for i := 0 to ComboBox1.Items.Count - 1 do Dispose(ComboBox1.Items.Objects[i]); ComboBox1.Clear; end;
