is there datatype mismatching happened?. warm google time without success. please help..

your data object needs json string. try

var datatosend = json.stringify({'path':'mydata'});  $.ajax({     type: 'post',     url: 'itemmaster.aspx/uploadfile',     contenttype: 'application/json; charset=utf-8',     data: datatosend,     datatype: 'json',     success: function (msg) {         alert(msg.d);     } }); 

be sure include json.js if supporting older browsers.
