hello Helen,

yes, of course, but in the on before post event of the query I'm doing some
extra checks on some fields, and if something is wrong I'd like to focus
the associated control:

var
TmpFld: TIB_Column;

begin
for I := 0 to Pred(My_IB_Query.FieldCount) do
begin
TmpFld := My_IB_Query.Fields[I];
if Assigned(TmpFld) and TmpFld.Visible then
try
if TmpFld.FieldName = 'SOMENAME' then
begin
Make some test on field SOMENAME;
if Something wrong then
raise EBadValueError.Create('The value is bad')
end;
.....
except
on E: EBadValueError do
begin
TmpFld.FocusControl;
raise
end
end
end
end;

The problem is that TmpFld.FocusControl does nothing. But maybe it's not
the correct usage?

Regards
Salvatore
