Trace AJAX webpage

I tried to trace AJAX enabled webpage and got the error:Sys.WebForms.PageRequestManagerParseErrorException. The message received from the server can not be parsed.

Any idea about that?

You can't use trace with Ajax. Trace kind of intercepts the page and reformats it so it can append the trace data. You'll have to try playing around with the debug functions that are part of Ajax Beta 1 and 2...


It should be possible to use tracing with MS AJAX. Just don't use in-page tracing. Set pageOutput to false, and look at the Trace.axd page.

Additional detailshere.


Thank you, muslon. It works.
