A DataRepeater would probably be a better way to do that.
That way you can spit out the full edit page GUI, and still have the paging.
The best way to do this is probably to just use the normal edit pages, and add prev/next buttons to it.
These buttons would then find the ID of the next/previous record, and redirect to the edit page passing that in the URL.
Finding the next/prev ID is the hard part, and why a DataRepeater may be nicer, though then you lose the ability to jump to specific IDs.
