Hi Martin,
Thanks for your advice. Now the column is sorted , But when I click on
heading arrow this one becomes unsorted instead desc sort and I can not return
back to sorted column?
Note: I can not set optionsgrid.og_sorted to true?
Best Regards
Med

TDBWidgetGrid has rows for the visible range of records only -> sorting must
be done in dataset. Please set according local indices where
tmsesqlquery.indexlocal[n].fields[0] is the sortfield.
If sorting should be based on a lookup value a field of FieldKind fkLookup
must be used. Do *not* activate LookupCache, set a local index on the
keyfield in lookup-dataset so directdata-access can be used.
IIRC sorting of lookup fields is supported in git master version only.
