Summary0031820: TDBEdit.Modified property don't reset after DataSet.Post
DescriptionProperty TDBEdit.Modified don't set to false after post changes to dataset.
Perhaps it's worth adding something like:

procedure TDBEdit.UpdateData(Sender: TObject);
  FDataLink.Field.Text := Text;
  Modified := False; //add
TagsNo tags attached.

What about other DB aware controls than TDBEdit?
I also wonder how this kind of error was not noticed earlier? Could others please confirm.
I don't do DB programming myself but I can apply patches if they are otherwise ignored.

Nobody uses TDBEdit or other datacontrol to check if a field changed, because you can connect a same dataset or same field with many data controls.
I think TField needs a Modified property.

You can take his code without side effects.

I forgot to ask the obvious question last time: Why was it important to reset TDBEdit.Modified while it is not useful for testing changed data?
Apparently it is used sometimes. Please see the related issue for details.
I plan to revert the change. We would need a solution to reset TDBEdit.Modified only after DataSet.Post instead of after every change.
