I don't understand. Do you want to tell the IDataProvider to retrieve new data (as you explained that you are doing database requests) or do you want to update the view for a single row. The last one should be achievable by fireing a RowUpdateEvent.
Thnx, I think RowUpdateEvent was, what i was looking for.
My workflow is the following:
- I trigger a RowUpdateEvent
- the NatTable asks the Body IDataProvider for new Data for this row
- IDataProvider looks up the DB
- the NatTable repaints the row with new data from IDataProvider
