Hello,
I have integer fields in the database which I can edit in NextDbGrid - also TNxDbLookupColumn-fields.
1. How do I empty them - get null in the Database?
That doesn't work: " nxgrdVermBericht.Cell[nxgrdVermBericht.SelectedCol, nxgrdVermBericht.SelectedRow].Empty := True;"
2. if TNxDbLookupColumn are null (new record) and I click on them it says "Variante des Typs (OleStr) konnte nicht in Typ (Integer) konvertiert werden" => "Typ OleStr couldn't be converted into Typ Integer"
how can it show empty when there is null in the database?
kind regards,
Lothar
