TDataSet:OnPreChange()
Publicado: Lun Mar 02, 2009 4:37 am
The documentation says "Event that is produced before the navigation pointer
changes position in the TDataSet."
I am wondering if this event is similar to OnPreAppend, however. In other
words, I am wondering if this event is fired every time the record pointer
changes in the dataset (like the documentation states), or instead, if this
event actually fires when a TDataSet:Edit() method is invoked.
I like to datestamp appends, edits, and deletes. I can datestamp a newly
added record very well with OnPreAppend, however I would like to do the same
with edits and deletes. I see that there is a OnPreAppend() event and
OnPreDelete() event, so datestamping appends and deletes shouldn't be a
problem, but I don't see a OnPreEdit. How can I do the same with edits?
TIA,
Gary
