Hi everybody, My app needs to filter table. So I do it on server side( in OnFilterRecord Event). But on client side, I have to use clientDataset.refresh() to get the changed data. This make my app very slowly. I tried to close ClientData and then open it, but it does'nt work. Furthermore, the first time when ClientData fetching the data, there are some errors: The server side filter the data from 100 records to 34 records, but the client side still get 90 records, displaying there are 34 records. But the second time, everything works fine. It display 34 records and telling you there are 34 records there. Any one has any idea? Thanks
