Save grid data from PageEventsBase plugin

If you programmatically are changing data in e.g. Record_PropertyChanged(…) { … }, you may want your changes to persist, and make sure the entity is saved.

Using the CrudAPI to either update or insert will create some tricky and annoying situations, so avoid that.

Instead, you can do this using the gridControl on the page entity provided by the PageEventsBase superclass.

NOTE: This will trigger the OnInsert override of the PageEventsBase plugin.
