asp.net ajax update some part after loading the rest of the webpage

A portion of my site requires data from a web service, with takes 7-8 seconds. How can I load the rest of the website, show a Updateprogress for the data which comes from开发者_Go百科 the service, than show the data once obtained trough a updatepannel.

Some working project would be great. Thanks

I need the server to retun the page before the data from service is obtained, and add that data later using ajax

if you are using Visual Studio 2008 then You can use AJAX Extensions tab in toolbox. There you can use UpdatePanel and UpdateProgress controll
