have you tried <asp:Repeater … EnableViewState=“False” >

you already seeing the problem. more data = more time to load
get used to using enableviewstate=false :slight_smile:

The only time I ever use viewstate, is only if it is needed. For forms or other pages with post backs that need to persist their data. I usually disable viewstate site wide in the web.config and then only enable it on pages that need it.

And on another note, why would you be loading 400 records into a repeater? I would strongly suggest paging on a control like this. Paging is easy with linq2sql, but can be done with normal ADO.NET if your not using linq2sql

Switch to MVC and you can avoid all of this.
