public mainpage() {     initializecomponent();     wcfreference.service1client obj = new wcfreference.service1client();     obj.getdataasync(10);         obj.getdatatabledataasync();         obj.getdatatabledatacompleted +=          new eventhandler<wcfreference.getdatatabledatacompletedeventargs>             (obj_getdatatabledatacompleted);  }  void obj_getdatatabledatacompleted(object sender,  wcfreference.getdatatabledatacompletedeventargs e) {     //pivotgridcontrol1.datasource = e.result.any1.tostring();      var data = e.result.any1.tostring();     xdocument xdoc = xdocument.parse(data);     list<string> lstnodes = new list<string>();      foreach (xnode item in xdoc.descendants("empname"))     {         lstnodes.add(item.tostring());     }      pivotgridcontrol1.datasource = lstnodes;    // pivotgridcontrol1.datacontext = lstnodes;  }
