This response does not have sense , since you use datatype as funcion.

Check what you do in this function and what you return from it.

Regards

any help will be appreciated. thank you in advance.

my js code is below:

$(document).ready(function () {

     $("#table").jqGrid({

         datatype: function () { getData(); },

         editurl: "About.aspx",

         height: 120,

         colNames: ['ID', 'CODEID', 'COMPID', 'UNAME', 'IVALUE', 'SNAME', 'MNAME', 'PNAME', 'CDATE'],

        colModel: [

           { name: 'ID', index: 'ID', jsonmap: 'ID', width: 80, sortable: true },

  { name: 'CODEID', width: 80, sortable: true, editable: true, editrules: { required: true, number: true} },

  { name: 'COMPID', width: 80, sortable: true, editable: true, editrules: { required: true} },

    { name: 'UNAME', width: 80, sortable: true, editable: true, editrules: { required: true} },

 { name: 'IVALUE', width: 80, sortable: true, editable: true, editrules: { required: true} },

 { name: 'SNAME', width: 80, sortable: true, editable: true, editrules: { required: true} },

 { name: 'MNAME', width: 80, sortable: true, editable: true, editrules: { required: true} },

 { name: 'PNAME', width: 80, sortable: true, editable: true, editrules: { required: true} },

 { name: 'CDATE', width: 120, sortable: false, editable: true, editrules: { required: true, date: true} }],

        imgpath: "Styles\images",

sortname: 'ID',

pager: '#gridpager',

sortorder: "asc",

loadtext: "Loading....",

viewrecords: true,

viewpages: true,

loadui: "block",

rownumbers: true,

loadonce: true,

rowNum: 5,

rowList: [5, 10, 20],

caption: "Jquery,JqGrid,WCF,Linq,Json",

onSelectRow: function (id) {

if (id && id !== lastsel) { lastsel = id; } }

  });

function getData() {

beginGridRequest("table");

var page = $('#table').getGridParam('page');

var rowNum = $('#table').getGridParam('rowNum');

var sortorder = $('#table').getGridParam('sortorder');

var sortname = $('#table').getGridParam('sortname');

var params = "page=" + page + "&rowNum=" + rowNum + "&sortorder=" + sortorder + "&sortname=" + sortname;

var url = "http://localhost:32775/WcfService/AjaxWcf.svc/SearchItem?" + params;

$.getJSON(url, {}, function (data) {

ReceivedClientData(JSON.parse(getMain(data)).rows);

});

setTimeout('endGridRequest("table")', 300);

 }

Json from wcf :  "page":"1","total":3,"records":"13",

data on pager is        Page  1of 0             View 1 - 5 of 5   ,  the right data should be   Page  1 of 3             View 1 - 5 of 13

does anyone have the same problem?
