Hi All,

Is it possible to make the OnDataChange event only get called on move
event (NEXT, FIRST, ....)?

Thanks in advance.

Phil.

Not without a deep change in fcl-db, but you can always ignore any
event in your handler. If you only want to react to "scroll" events
then do nothing unless: not Assigned(Field)

As the documentation states:
QuoteIf the dataset has scrolled, then the Field parameter is Nil
