WEB PROJECT IN ASP NET C#

Question

I'm working on a WEB PROJECT IN ASP NET C#.

 

I'm looking for bests practises for :

 

- ListView (and sub listview in the same page)

- handle large datas in listview with datapager

- manage postbacks and keep datas in listview (without sessions because i've heard that was not terrible) 

 

I prefer to set datasource of the listview in code behind (c#) 

 

THANKS FOR YOUR HELPS !
