The common ancestor with the two grids has the code
"
procedure tdoublegridpagefo.enterev(const sender: TObject);
begin
editfo.dataso.dataset:= tdbwidgetgrid(sender).datalink.datasource.dataset;
end;

Probably the simplest solution for your case is the already showed use of
igriddatalink and idbeditfieldlink in onfocusedwidgetchanged event of
tbaseeditfo:
"
procedure tbaseeditfo.focusedwidgetchangedev(const oldwidget: twidget;
const newwidget: twidget);
var
intf1: idbeditfieldlink;
intf2: igriddatalink;
begin
if (newwidget <> nil) then begin
if newwidget.getinterface(idbeditfieldlink,intf1) then begin
dataso.dataset:= intf1.getfieldlink().dataset;
end
else begin
if newwidget.getinterface(igriddatalink,intf2) then begin
dataso.dataset:= intf2.getdatalink().dataset;
end;
end;
end;
end;
"
