格式2：

主要区别于正常datagrid 的就是多俩属性：

idField: 'id',
treeField: 'YearTitle',

$('#billlist_PaidUse').treegrid({
            url: 'FinancialAuditService.ashx?Method=GetBillList_PaidUse_TreeGrid&ContractGuid=' + $("#contractid").val(),
            nowrap: false,
            rownumbers: false,
            singleSelect: false,
            fitColumns: true,
            idField: 'id', //注释该属性 否则getSelections方法返回总数只能为1
            treeField: 'YearTitle',
            loadMsg: '正在加载数据……',
            toolbar: '#toolbar',
            columns: [[
               { title: '唯一guid', field: 'Year',  100, checkbox: true },
                { title: '年份', field: 'YearTitle',  80, align: 'center' },
                { title: '应收金额', field: 'Receivable',  80, align: 'right' },
                { title: '<span class="jeClass">已收金额</span> ', field: 'Paid',  80, align: "right" },
                { title: '欠收金额', field: 'Arrears',  80, align: 'right' },
                { title: '有效期限', field: 'TimeLimits',  140 }
            ]],
            toolbar: '#tbBillToolPaidUse', // id 为tb的Div 详细 查看前台页面HTML代码
            onBeforeLoad: function () {
                $(this).datagrid('rejectChanges');
            },
            onClickRow: function (rowIndex, rowData) {

            },
            onDblClickRow: function (rowIndex, rowData) {
            }
        });
