I am using Atlas April Release for building the application.

1) Our application has a page that loads menu items/actions dynamically based on the user profile.

2) The rest of the page has Webparts placed in Webpart Control Zones which inturn are placed in Atlas Update Panel.

So on the application initialization, I have the following page loaded:

http://myatlas/Default.aspx?Page=Profile

And when the user navigates to another menu item on the page, the query string is changed (for example to Service Info) to retrieve the relevant items for that page. We had overwritten the Personalizatin Providers to take query string as path. So far everything is fine and webparts were loading smoothly.

The problem is, the whole page gets refreshed. Ofcourse, we are using Response.redirect method.

So how do we avoid page refresh and give the user AJAX experience?

The application consists of only webparts and it is suffice to reload the webparts based on the Query string?

Any ideas? Pointers?!! Greatly appreciated?

Hi Mike,

Thanks for the reply.

The page is not redirected to a new page in the project. The page is being redirected to the same page with a different query string.

Let me clarify myself again.

I have a page called Default.aspx.

The Default.aspx, has four different tabs and has three static webpartzones.

When the application is started, default.aspx is loaded. The application user is given ability to add relevant Webparts/User controls dynamically on to the page. When the user clicks on tab1, we are required to load the tab1 associated information. (To accomplish this, we had overwritten methods in the SQLPersonalization provider, to store the path information with the query string, eg Default.aspx?tabid=1 etc).

It is in this scenario, when the application user moves from tab1 to tab2, the page is getting refreshed? Is there any way to avoid this?  (Will Postback work in this scenario?)

(We have seen websites like Pageflakes, netvibes accomplishing this task. Is there a way similar to that?) We are using Atlas April CTP and our webpart zones are placed within Atlas Update Panel.
