this goes beyond the scope of NatTable itself. What you need to do is write your own IDataProvider (or IRowDataProvider) and try to react on scrolling. You might also need to rewrite some code that will call the DB instead of working on the local list.
As we are consultants, feel free to book us for such advanced topics that are going beyond the scope of the NatTable as a widget to visualize and deal with local content.
Thnx Dirk, I will book you as consultants, when I stuck somewhere
Regarding my question:
I have allready a IRowDataProvider, which triggers the DB.
It was unclear, whether or not I will need the GlazedLists? I suppose not, because I do not have any Lists, which I can monitor...
