Javascript jqGrid Treegrid日期排序无法正常工作

我使用jqGrid 4.4.0和jQuery 1.7.2（我还尝试了最新版本的jqGrid和jQuery）。我这样使用treegrid：

    jQuery('#projects_grid').jqGrid({
                treeGrid: true,
                treeGridModel: 'adjacency',
                ExpandColumn: 'ProjectName',
                url: 'jqGridTestHandler.ashx?q=tree',
                treedatatype: 'xml',
                mtype: 'POST',
                colNames: ['RID', l_('ProjectName'), l_('CustomerName'), l_('StartDate'), l_('EndDate'), l_('ManagerName'), l_('SourceLang'), l_('TargetLang'), l_('DomainName'), '', ''],
                colModel: [
{ name: 'RID', index: 'RID', hidden: true, key: true },
{ name: 'ProjectName', index: 'ProjectName' },
{ name: 'CustomerName', index: 'CustomerName' },
{ name: 'StartDate', index: 'StartDate', width: '80px', align: 'center'},
{ name: 'EndDate', index: 'EndDate', width: '80px', align: 'center' },
{ name: 'FullName', index: 'FullName', align: 'center' },
{ name: 'SourceLang', index: 'SourceLang', width: '110px', align: 'center', formatter: flagFormatter },
{ name: 'TargetLang', index: 'TargetLang', width: '110px', align: 'center', formatter: flagFormatter },
{ name: 'DomainName', index: 'DomainName', width: '110px', align: 'center', formatter: domainNameFormatter },
{ name: 'IsExternal', index: 'IsExternal', hidden: true },
{ name: 'myac', fixed: true, sortable: false, resize: false, width: '30px'}],
                height: '345px',
                loaded: false,
                shrinkToFit: false,
                pager: '#projects_pager',
                rowNum: 10,
                autowidth: true,
                rowList: [10, 20, 30],
                viewrecords: true,
                sortorder: 'desc',
                altRows: true,
                toolbar: [true, 'top'],
                ExpandRowClick: true,
...some events (loadcomplete etc..)

我错了什么？

您应该在

'StartDate'

和

'EndDate'

列中使用

格式设置程序：“日期”

和正确的

格式选项。当前设置（默认选项）通知jqGrid将数据解释为字符串。要以类似于
22.04.2013
的格式对日期进行正确排序，应在列定义中包含以下附加属性：

格式化程序：“日期”，格式化选项：{srcformat:“d.m.Y”，newformat:“d.m.Y”}
日期列的数据类型不是日期类型。将数据类型从
varchar
更改为
date
。在此之后，您必须使用单元格设置日期格式。谢谢您Oleg和@Amit Garg。我已经把你的两个答案结合起来了，这是正确的。最终代码：
sorttype:'date'，formatter:'date'，formattoptions:{srcformat:'d.m.Y'，newformat:'d.m.Y'}
