Datasource OnDataChange
« on: May 30, 2020, 06:54:37 pm »
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:
