your datatype text , response in json

try this

 datatype: "json",

and think success function should be

  success: function (data) {       alert(data.d.length);               $("#<%=txtfname.clientid%>").val(data.fname);             $("#<%=txtlname.clientid%>").val(data.lname);             $("#<%=txtaddress.clientid%>").val(data.address);             $("#<%=txtemail.clientid%>").val(data.email);               debugger;          }        }
