AFAIK, the TDBGrid and TDataSet are interacting correctly - TDataSet buffers the records it contains in memory, and won't make them available until all records are in, so to speak.
On a different approach... by TDataSet, do you mean a TTable? You might try a TQuery instead; depending on the database you're using, and what it is you're trying to achieve, it might be an appropriate solution for you. What exactly are you using as a database, and how does the user interact with the grid in your application?
