We are using the grid control and have many users that need to include a large number of columns (100+). I know that having a large number of columns affects performance. We have vertical paging enabled and that is helping some with performance, but it is still taking too long to render the grid with 100+ columns. It would be great if you could add horizontal paging support to the grid. That way, we could specify that only X columns be displayed per horizontal page and then be able to attach a paging control to also manage the horizontal paging.
