mmhhh… I was looking with firebug, the scripts are not altered… the problem looks like in certain cases ajax needs the “original version” of the html that the page rendered, and only 1 change (like adding some text something to the response) causes the failture to the postback…
anyway, I already solved 80% of the performance issue I had on this site, so I am pretty happy…
Thanks a lot for your code and your answers and have a nice day!!

I think you might be altering script in addition to html. Try using fiddler or firebug to see the response you're getting back from the server to make sure it's what you're expecting.

At least you're able to create a workaround for the broken pages. It might be a minor enough issue that it's not worth digging deeper. The real killers are full page loads more than ajax updates.

eehhh… I tried to disable eventvalidation, but with no results… I am using VS2008, .Net Framework 3.5 and Ajax 3.5.
Actually, I have this error only on few pages, so I created a new class for my pages and I am inheriting the new class only in the pages that do not have this error…

Could this possibly be a fix?

If not, what version of Ajax & .net are you using?

Hi, Thanks for the reply. The error I get is:

Errore: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near 'ol”>IvaTotale<'.
File sorgente: http://localhost/Memento/ScriptResource.axd?d=m...
Riga: 5

if I just execute writer.write(strHtml) without any replace it works (but of course the page code is still with whitespaces)

I don't use update panels in .net. I use jQuery and JavaScript calls instead but maybe I can still help. What's the error you're getting?

Hello, great code, but unfortunately it's not compatible with .net ajax… if controls are inside an updatepanel you receive an error…
do you have any solutions?
Thanks
