Aspx page looses css sytles when coming from another aspx page

Really weird problem I am running into.  When I load my main aspx page it comes up just fine with all the css styling intact and all fucntions on the page work.  however when i come from another page and pass a vlue to my main page to automatically load information it looses all styling and none of the ajax toolkit things work on the page.  As soon as I post back the page everything return to normal.  It is just when I pass a value into the page to load from another aspx page.  Never had this happen beofer and its quite perplexing.

I am using a master page with both page but that is not affected at all it just the css on the form where i am showing data.
