the web service.asmx methods not being fired @ when inspect network request through firebug .the url not being resolved correctly.try putting full path website service path this
servicepath="http://smirdex.gr/orderform2.2/webservice.asmx" or resolve url
servicepath="<%# resolveurl('~/orderform2.2/webservices.asmx') %>" let me know how goes
