未启用jqgrid分页按钮

Question

我不知道分页按钮的代码有什么问题不能显示

function LoadAgencies(Action, User, FA) {
$grid = $("#grdAgencies");
$grid.jqGrid({
    url: "dhFollowUp.ashx?1=1",
    postData: {
        Action: Action,
        User: User,
        FANo: FA
    },
    height: 320,
    width: 760,
    datatype: "json",
    mtype: "GET",
    colNames: ['Mark for Reports', 'OA #', 'Oper. Agency', 'OB #', 'Building Name','Survey Count', 'CADR', 'Select', 'EntID'],
    colModel: [
            { name: 'ab', index: 'ab', width: 45, formatter: 'checkbox', formatoptions: { disabled: false }, align: 'center', sortable: false, search: false, hidden: true},   //,  align: 'center' 
            { name: 'OANo', index: 'OANo', width: 30, sortable: false, search: false, align: 'center', editable: false },
            { name: 'OANm', index: 'OANm', width: 125, sortable: true, search: true, align: 'left', editable: false },
            { name: 'OBNo', index: 'OBNo', width: 30, sortable: false, search: false, align: 'center', editable: false },
            { name: 'OBNm', index: 'OBNm', width: 125, sortable: true, search: true, align: 'left', editable: false },
            { name: 'FCnt', index: 'FCnt', width: 60, sortable: false, search: false, align: 'center', editable: false },
            { name: 'ab1', index: 'ab1', width: 40, sortable: false, search: false, align: 'center', formatter: CADRLink},   // 
            { name: 'ab2', index: 'ab2', width: 40, sortable: false, search: false, align: 'center', formatter: SurveyLink},      // 
            { name: 'EntID', index: 'EntID', width: 10, hidden: true },
    ],
    emptyrecords: "No records for this Agency",
    loadtext: "Loading Agency Records...",
    viewrecords: true,
    gridview: true,
    rowNum: 1,
    rowList: [1,2,5],
    contentType: "application/json; charset=utf-8",
    caption: "Follow Up Agencies",
    multiselect: true,
    pgbuttons: true,
    pager: '#pgrdAgencies',
    gridComplete: function () {
    }, // end of gridcomplete
    onSortCol: function (index, idxcol, sortorder) {
        if (this.p.lastsort >= 0 && this.p.lastsort !== idxcol
               && this.p.colModel[this.p.lastsort].sortable !== false) {
            $(this.grid.headers[this.p.lastsort].el).find(">div.ui-jqgrid-sortable>span.s-ico").show();
        }
    },
    loadError: function (xhr, status, error) {
        MsgBox("Loading FollowUp Agency Grid: " + error);
    } //end of loadError
});      // end of grdAgencies

colModel = $grid.jqGrid('getGridParam', 'colModel');
$('#gbox_' + $.jgrid.jqID($grid[0].id) +
            ' tr.ui-jqgrid-labels th.ui-th-column').each(function (i) {
                var cmi = colModel[i], colName = cmi.name;

                if (cmi.sortable !== false) {
                    $(this).find('>div.ui-jqgrid-sortable>span.s-ico').show();
                } else if (!cmi.sortable && colName !== 'rn' && colName !== 'cb' && colName !== 'subgrid') {
                    $(this).find('>div.ui-jqgrid-sortable').css({ cursor: 'default' });
                }
            });

var AgencyGrid = jQuery("#grdAgencies").jqGrid('navGrid', "#pgrdAgencies", { edit: false, add: false, del: false, search: false, refresh: false });

jQuery("#grdAgencies").jqGrid('navButtonAdd', "#pgrdAgencies", {
    caption: "Toggle Search", title: "Toggle Search Toolbar", buttonicon: 'ui-icon-pin-s',
    onClickButton: function () {
        AgencyGrid[0].toggleToolbar()
    }
});
jQuery("#grdAgencies").jqGrid('navButtonAdd', "#pgrdAgencies", {
    caption: "Clear Search", title: "Clear Search", buttonicon: 'ui-icon-refresh',
    onClickButton: function () {
        AgencyGrid[0].clearToolbar()
    }
});

jQuery("#grdAgencies").jqGrid('filterToolbar');

} // LoadAgencys的结尾

有一个下拉列表，用户可以从中选择以填充网格。打开页面时页面上会显示网格结构。 这就是代码：

    $('#ddlSelectFA').change(function () {
    if ($('#ddlSelectFA').val() == 0) {
        MsgBox('Please select a Fiscal Agency');
    }
    else {
        $('#grdAgencies').jqGrid('setGridParam', { postData: { Action: "MANAGEAGENCIES", User: $('#hdfldUser').val(), FANo: $('#ddlSelectFA').val() } }).trigger("reloadGrid");
    }
}); // end of ddlSelectFA change

我希望上面的内容足以让我知道为什么我没有看到按钮，即使我有（4）条记录并且每页显示1条。

谢谢
