Hello Harrald,

thanks for your help and the informing phone talk we had last night.

>Query.refresh retrieves the whole dataset from the server again.

Is that really so? If I scroll down on a grid showing a table with many rows mostly a dialog opens showing the "<x> rows fetched" with a incrementing value for <x>. This process takes much longer than a Query.Refersh. Therefore I think, that only the rows are fetched from the server which will be displayed in the grid. Am I wrong here?

Regards
Rainer
