Ok! this is to show the data in a gridview but how would I do it when I am using a panel where I have all the textboxes to display the data. I am not using any tools like gridview or detailsview..I might have to have a loop where for previous records, I would have i-- and for next records, I would have i++. But I don't know how to actually write it...
