Sorry about the multi-posting, but it does not seem as though the other
newsgroups are frequented enough to get any advice on this problem...If
anyone can possibly help, I would greatly appreciate it, I've spent three
days trying figure out why paging won't work for me...TIA.
I've been to gotdotnet.com/quickstart...samples and reviewed the Source
control for adding paging to datagrids, my problem is that we do not connect
to an SQL Server, we are using an RPC to get the data from a DB2 database
using COBOL. It is a difficult way to get connected, and causes problems
when I'm trying to do something that's supposed to be as simple as paging
for a datagrid. When I select the page number to go to, I get a blank
screen, with Currentpageindex is 1 and PageCount is 0. Why doesn't it page
correctly? Here is my code...Any suggestions?
