No, this doesn't work. I have overriden both Functions with Result:=false,
but nothing changes.
I had another idea, when the dataset is PreventEditing:=true, I set the
Grid.readOnly:=true, but I haven't found the event, to react on changes to
the dataset. I tried SysStateChanged, but this doesn't work for me. Any ideas
?
