UpdatePanel causing full postback with SqlDatasource

Hi I've been running around trying to fix ONE problem for days now and getting to point of giving up.

I've got a listview that's using an updatePanel with Timer so that just the listview updates not the entire page and it works fine on the local server but when up on webserver its having none of it. I stripped it back as far as I could and it looks like the full postback is occurring because the listview updates from the sqldatasource which is obviously essential or the listview can't get any data.

What's going on here? There must be a way to update the listview withing a full page postback, I've been through so many forum posts and tutorials to find different methods to do this but to no avai开发者_如何学编程l.

If anyone can help I would be extremely grateful, thankyou in advance
