[RESOLVED] Can't trace what's causing the full page postback

[ssystems]

I have a page that have multiple user web controls in it. On one of the controls I have a datalist wrapped in an update panel. The items in the datalist is another control wherein I have a delegate. My issue is on the first firing of the event I got a full page postback then the next clicks don't. I want to eliminate the full page postback as I have a reset on my Page_Load (!IsPostBack). Using viewstates is not possible as the object I'm using is not serializable. Need tips on where to look at. Thanks

Guess 34 views is not enough to point out any direction.

Ok for some reason it works perfectly on my sandbox but not on the development box. Yes they are the same code and libraries used. Now I'm wondering what's in my dev box's settings that's causing it. Will just add this to my long list of whys but if anyone got an idea as to "WHY" just let me know.thanks.
