Try ro raise an exception on the DataSet's Table's on RowChanging event.
Not exception raises
why ?????
Same behavior on the ItemChanged event of the CurrencyManager
Dimitris
Basicly relative to my prior post (See DATASET vs CURENCYMANAGER vs
CONTROL)
Does anyone have any idea where to write NewRecord Field assignments and
where to do checks (nulls , business logic or set some values ) of
before post of DataRow on System.DataSet ??????
You consider this
Most of all you use this events on VCL
AfterScroll
NewRecord
BeforePost
BeforeDelete
Hot simulate these events on System.DataSet's dataTable ?????
Thanks
Dimitris
