How to know the first item and last item in dataTable ?

[daclan]

I used RichFaces DataTable to display the items of a list. In my UI, if this is a fist item, I will display a down arrow. And if this is the last item, I will display an up arrow.

I would like to know if there is a way in DataTable that tells me that an item is the first one or the last one in the list ?

Look into using the rowKeyVar attribute.

If it's zero then it's the first row. If it equals your table size (less 1 I think?) then it's the last row.

Cheers,

Damian.
