data-aware

In the helpfile entry for TDBComboBox, it says that the text of the selected option becomes the new value for the field. Is there any similar control that goes by ItemIndex instead of text? (To represent an enumerated type, for example.) Try the TDBLookupComboBox. Check out the ListField, DataField and KeyField properties. You can fill TDBComboBox items with numbers ('0, '1', '2', ...), but set DBComboBox1.Style to csOwnerDrawFixed and write OnItemDraw event. Something like this: procedure TForm1.DBComboBox1DrawItem(Control: TWinControl; Index: Integer; Rect: TRect; State: TOwnerDrawState);

Does anyone know of a TDataset descendant that works with Generics and RTTI, so that I can write code like this, and make use of data-aware components in the GUI? : ... ds:TDataset<TPerson>; ... procedure DoStuff; begin ds:=TDataset<TPerson>.create; ds.add(TPerson.Create('A.','Hitler',77)); ds.add(TPerson.Create('O.','Bin Laden',88)); end; This should be possible. The fielddefs can be created via RTTI because the exact type of the data is known. Values can also be automatically marshalled back and forth, so you can both view and edit data that's in a class or a record. I hate having to write a

What is the preferable way to write Delphi database applications using transactions and also data-aware components? I have to write a client app that access InnoDB tables, and do some master-detail kind of things inside transactions. After doing some research on transactions (from general point-of-view), then I humbly make a conclusion that non data-aware components and hand-coded SQL would be the "perfect match" of transactions; But the data-aware components wouldn't be. They don't seem to be made for each other. I have the real need to use transactions, but on the other hand I could not just
