Do you mean JSON? "Does not work" is not informative.

Yes its Json, I have this code for autocomplete action for textbox, this is simply works if i open property pages and set build option to framework 3.5 rather than 2.0
but i want this to be worked in asp.net framework 2.0
i got Error in below setion :
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(request.term);
alert(XMLHttpRequest);
alert(textStatus);
}

this XMLHttpRequest alert is showing me "object XMLHttpRequest" error.
and my reqest is not even sent to webservice method(my method is not calling).
i hope this helps you to solve my issue.

Just forget about calling mentioned method, just make it work that it can call any webmethod.
