Delphi calculated field and OncalcFields eventYour TDataSet, Ttable or TQuery has AutoCalcFields property set to try, by the event OnCalcFields didn't fire. In the case of a query, you opened the query Code:query1.open;
while not query1.EOF do
query1.next;
You may have missed the definition of the calculated filed, eg. Code: object TblDevDesc: TStringField
FieldKind = fkCalculated
FieldName = 'Desc'
Size = 40
Calculated = True
end
TQuery example:Code: object Query1: TQuery
AfterScroll = Query1AfterScroll
OnCalcFields = Query1CalcFields
DatabaseName = 'ARESLITEDB'
SQL.Strings = (
...
}
object TblDevDesc: TStringField
FieldKind = fkCalculated
FieldName = 'Desc'
Size = 40
Calculated = True
end
