how to get a list of Datakeys from an ajax.net Reorderlist

[Stimp]

Say I have an ajax.net reorderlist with datakeys like:

- 1233
- 4556
- 994
- 3555

(all unique rows)

Say I move the 1st item to the 3rd position so I have:

- 4556
- 994
- 1233
- 3555

How can I create a comma-delimited string of these values in the
ItemReorder() function of the reorderlist.

e.g. I want "4556,994,1233, 3555" when I reorder the list as above.

I can't seem to access the updated list on the ItemReorder.

Any ideas??
Thanks.
