full postbacks with ASP.Net AJAX on an ASP.NET page within an IFRAME

Question

I have an ASP.Net page that is contained within an iframe the page has an update panel, that, in isolation, works however when the page is within the iframe, the update panel always produces a full postback. I guess that the problem is the iframe itself but id like to know

a) why it doesnt work b) if there is a solution beyond rolling my own controls and writing a whole load of js

EDIT

ok its ASP.Net 2.0 and the 1.0 toolkit the page broadly looks like this (Note for the pedants i haven't closed tags, this is just to show the basic structure)

Main Page
Form
     table 
         td 
             iFrame 
                ! -- contained page --
                 Form 
                     asp:ScriptManager  
                         asp:UpdatePanel 
                               asp:Repeater

Answer 1

I have been using some of my pages in IFrames using UpdatePanel, and they DO NOT produce any full page postbacks.

Can you describe the whole setup in more detail?

EDIT: Hmmm. The setup looks OK. Did you check whether the control which triggers the postback is placed inside the panel? Also, did you check for JS errors occuring before the ajax request fires?

Answer 2

Today I came across the same problem (trying to load gridviews asynchronously): A postback inside an iframe would reload the whole page, and ignore the postback event handler.

My solution was to use UFRAME.
