OK, im really lost and really hoping you experts can help me. I have a datagrid that is bound by a dataset. I have paging enabled and 5 per page. So far everything works, untill you go to view the second, third, etc page. Then it stops. From what I understand, I need to tell it to pull teh data from the dataset. How do I do this?
