  },
  {name:'action'}
],
rowNum:10,
rowList:[10,20,30],
autowidth: true,
height: "100%", 
pager: '#pager',
sortname: 'id',
viewrecords: true,
rownumbers: true,
sortorder: "asc",
editurl: "control.php?case=8",
onSelectRow: function(id){
  if(id && id!==lastsel){
    grid.jqGrid('restoreRow',lastsel);
    grid.editRow(id,true);
    lastsel=id;
  }
}

});

everything works fine but i can't figure how to check the server response after row is saved

any help would be great

Thanks

You can use aftersavefunc and errorfunc parameters of saveRow.
