problem loading data in details jqGrid from master grid?

问题

When I am making a call first time it shows data in my details grid from master grid but when selecting other row its not populating the new data in the details grid..

jQuery("#list10").jqGrid({
    sortable: true,
    url: '/cpsb/unprocessedOrders.do?method=getInitialUnprocessedList',
    datatype: 'json',
    colNames: ['Order', 'Load', 'Gate Time', 'Stop', 'Customer', 'Status'],
    colModel: [
        { name: 'orderNumber', index: 'orderNumber', width: 120, align: "center",
          sorttype: "int", key: true },
        { name: 'loadNumber', index: 'loadNumber', width: 100, align: "center",
          sorttype: "int" },
        { name: 'latestTime', index: 'latestTime', width: 160, align: "center",
          align: "center" },
        { name: 'stopSeq', index: 'stopSeq', width: 80, align: "center",
          sorttype: "int" },
        { name: 'customerNumber', index: 'customerNumber', width: 60,
          align: "center", sorttype: "int" },
        { name: 'orderStatus', index: 'orderStatus', width: 120, align: "center" }
    ],
    rowNum: 10,
    rowList: [10, 20, 30],
    jsonReader: { repeatitems: false,
        root: function (obj) {
            return obj;
        },
        page: function (obj) { return 1; },
        total: function (obj) { return 1; },
        records: function (obj) { return obj.length; }
    },
    pager: '#pager10',
    sortname: 'Gate Time',
    sortorder: "desc",
    gridview: true,
    loadonce: true,
    viewrecords: true,
    multiselect: true,
    multikey: 'ctrlKey',
    caption: "Order Header",
    onSelectRow: function (ids) {
        if (ids == null) {
            ids = 0;
            if (jQuery("#list10_d").jqGrid('getGridParam', 'records') > 0) {
                jQuery("#list10_d").jqGrid('setGridParam', { url:
"/cpsb/unprocessedOrders.do?method=getUnprocessedOrderDetails&orderNum=" + ids });
                jQuery("#list10_d").jqGrid('setCaption',
                        "Order Header: " + ids).trigger('reloadGrid');
            }
        }
        else {
            jQuery("#list10_d").jqGrid('setGridParam', { url:
"/cpsb/unprocessedOrders.do?method=getUnprocessedOrderDetails&orderNum=" + ids });
            jQuery("#list10_d").jqGrid('setCaption',
                      "Order Details: " + ids).trigger('reloadGrid');
        }
    },
    height: '100%'
}); 
jQuery("#list10").jqGrid('navGrid','#pager10',
       {view:true,add:false,edit:false,del:false,searchtext:"Filter"},
       {},{},{},{multipleSearch:true});
$("#list10").jqGrid('hideCol', 'cb');

2nd grid for order details

jQuery("#list10").jqGrid('reloadGrid');
jQuery("#list10_d").jqGrid({
    height: 100,
    url: "/cpsb/unprocessedOrders.do?method=getUnprocessedOrderDetails&orderNum=",
    datatype: "json",
    colNames: ['Order', 'SKU', 'UPC', 'Item Description', 'Quantity Ordered',
               'Teach in Hold?'],
    colModel: [
        { name: 'orderNumber', index: 'orderNumber', width: 55 },
        { name: 'sku', index: 'sku', width: 55 },
        { name: 'upc', index: 'upc', width: 40, align: "right" },
        { name: 'itemDescription', index: 'itemDescription', width: 150,
          align: "right" },
        { name: 'quantityOrdered', index: 'quantityOrdered', width: 150,
          align: "right", sortable: false, search: false },
        { name: 'teachInId', index: 'teachInId', width: 150,
          align: "right", editable: true, edittype: "checkbox",
          formatter: 'checkbox', editoptions: { value: "true:false"} }],
    rowNum: 5,
    rowList: [5, 10, 20],
    jsonReader: { repeatitems: false,
        root: function (obj) {
            return obj;
        },
        page: function (obj) { return 1; },
        total: function (obj) { return 1; },
        records: function (obj) { return obj.length; }
    },
    pager: '#pager10_d',
    sortname: 'SKU',
    loadonce: true,
    viewrecords: true,
    sortorder: "asc",
    multiselect: true,
    multikey: 'ctrlKey',
    caption: "Order Detail",
    height: '100%'
}).navGrid('#pager10_d', { view: true, add: false, edit: false, del: false },
            {}, {}, {}, { multipleSearch: true });
$("#list10_d").jqGrid('hideCol', 'cb');
jQuery("#ms1").click(function () {
    var s;
    s = jQuery("#list10_d").jqGrid('getGridParam', 'selarrrow');
    alert(s);
});

Edit: I am able view different records once I refresh the page...But after one selection other selection don't work

edit2: after debugging i saw that I am appending the orderNum parameter correctly but this is not making any call to the action class....any idea? thanks!

It seems to me that the answer on your main problem you find here: JqGrid Reload not working.

Because you use loadonce:true in both grids, the datatype in every grid will be changed from "json" to "local" after the first load. It seems to me that you should just remove loadonce:true for the second (detailed) grid. If you do want use loadonce:true for example for local sorting or local paging, then you should reset datatype to "json" in the same call jQuery("#list10_d").jqGrid('setGridParam',{url:"...", datatype: "json"}); .
