Rendering Ajax panels concurrently.

Question

Hello All,
I want to develop a web parts like functionality in asp.net 2.0, it means I have 4-5 panels on a page and each panel containing a gridview. I want all of them to load in their repsective panels SEPARATELY. It means that if a gridview of panel1 is having only 1 record, it should get displayed immediately without waiting to load gridview of panel2. For live example of this functionality please visit http://www.google.co.in/ig?hl=en&source=iglk. Here, each panel gets rendered separatley. Please note here that I used AJAX panels but they are meant for asynchronous postbacks, I want them to render concurrenly when NOT IS POSTBACK.
Do reply at the earliest as I am in need of this functionality urgently.
Thanks to all techies.
