Custom Paging in datagrid

[anon]

hi all,
i have tried implementing custom paging using the example from 4 guys
from rolla....however example doesnot work as desired.....i.e when the
pagecount is 1...and current page index is 0(for the first page...then
nothing hapens and it does not move to next page...am i missing
something?

http://www.4guysfromrolla.com/webtech/code/CustPaging.aspx.html

this is the part i m talking about...
Select arg
Case "next":
If (Pubs.CurrentPageIndex < (Pubs.PageCount - 1)) Then
Pubs.CurrentPageIndex += 1
End If

note...i have implemented it in C#....but logic is the same

thanks..
Ben
