json 数据也是正常的，有_parentId,也有根节点。
$('#test').treegrid({ title:'详情', iconCls:'icon-save', width:700, height:350, nowrap: false, rownumbers: true, animate:true, collapsible:true, url:"/OtherHtml/handler/02503/content.ashx?keyId="+keyId+"", idField:'id', treeField:'ym00402', frozenColumns:[[ {title:'编号',field:'ym00402',width:200, formatter:function(value){ return '<span style="color:red">'+value+'</span>'; } } ]], columns:[[ {field:'bs00203',title:'商品名称',width:150}, {field:'bs00102',title:'商品类别',width:220,rowspan:2}, {field:'st00102',title:'计量单位',width:150,rowspan:2}, {field:'ym00405',title:'数量',width:150,rowspan:2}, {field:'bs00205',title:'规格',width:150,rowspan:2}, {field:'ym00410',title:'单价',width:150,rowspan:2}, {field:'ym00411',title:'金额',width:150,rowspan:2}, {field:'ym00406',title:'损耗',width:150,rowspan:2}, {field:'ym00408',title:'备注',width:150,rowspan:2} ]]
})
为什么没数据
问题补充：
无力吐槽了，尼玛 这是回事，我在easyui官方网站上下载的demo，demo 里面包含的jq和easyui 2个版本居然有问题。下了个最新版本什么问题都没有

jq和easyui 版本问题

后台访问数据库用的是什么？
LINQ to Sql还是EF还是ADO.net
收获园豆：6
ADO.net,返回来的json 应该是没问题的
@亦有哭亦有笑:
我也遇到过这样的问题，
json数据没问题，后台调试也没问题，但是前台就是数据不显示，最后我自己手动创建了一些实体类，然后在后台装箱拆箱，前台数据展示的是我实体类的类型，然后数据就出来了。
因为我用的是EF，同事说这是EF自动创建的实体类类型有问题，必须要自己再创建实体类，
不知道你那是不是和我以前一样的情况

看了下你的数据，发现你的数据可能有问题。id和_parentId一致，这个应该不对，而且，第一条数据没有_parentId

第一条数据 是根节点，是没有_parentId，他去子节点格式不一样。另外，我将id和_parentId都改为int类型，还是没结果
@亦有哭亦有笑: 把你的新的数据贴出来看下？我觉得可以去官方demo上拿数据格式下来，然后套上你自己的数据。

给个思路解决问题：
1、easyui的官方示例代码中有关于treegrid的示例，将原有的json数据改为你问题中贴的json数据，看是否能出来treegrid
2、若没有出来证明不是你js生成treegrid的问题，是你生成的json数据有问题，检查你的url请求的地址，重新组织json（个人感觉这个问题概率大）
3、若是出来了，就麻烦了，应该是你的js生成treegrid的问题，对照示例程序，看看是不是有属性设置不合适

我将treegrid 改为原始的datatgrid 正常显示

json数据的最外层去掉。。只留json数组看看
收获园豆：6
去掉最外层的话，子节点没有包含在根节点下面，
根节点的json数据，没有_parentId
bs00102: "第一类" bs00202: "SPZL000001" bs00203: "自行车" bs00205: "山地自行车" id: 1
子节点
_parentId: 1 bs00102: "第一类" bs00202: "SPZL000002" bs00203: "车轮胎" bs00205: "山地轮胎" id: 2
@亦有哭亦有笑: 看错了 以为是datagrid...
你设置的主键 idField:'id'，但是你最外层没有id这个字段呀。。？
编号就是id （1，2，3）就是id啊,设置在第一列还是一样
@亦有哭亦有笑: 你的数据源是不是这个
{"total":3,"rows": [{"id":"4060d01f-c6a1-4b8e-9b03-a2904d4cfebe","ym00402":"4060d01f-c6a1-4b8e-9b03-a2904d4cfebe","ym00403":"","ym00404":"","ym00405":1.0000,"ym00406":0.00,"ym00408":"","ym00410":0.00,"ym00411":0.00,"bs00202":"SPZL000015","bs00203":"W=2A(2x+4y)+3B(x+3y)","bs00205":"","bs00102":"测试组","st00102":"个"}]}？
是的话 根节点哪里有id 了 ,,?
@咦？:
{"total":4,"rows": [{"Id":1,"ym00402":"b32300e4-e647-4e48-944a-62e959142507","ym00403":"","ym00404":"","ym00405":1.0000,"ym00406":0.00,"ym00408":"","ym00410":0.00,"ym00411":0.00,"bs00202":"A2","bs00203":"2-A","bs00205":"","bs00102":"多层测试","st00102":"个","ym00301":"0","_parentId":""},{"Id":2,"ym00402":"b32300e4-e647-4e48-944a-62e959142507","ym00403":"0ddc9fb5-7423-43e4-afe8-85d2d34d0684","ym00404":"c3dec451-43db-4117-a4bb-2124fcb77c52","ym00405":2.000000,"ym00406":"","ym00408":"","ym00410":0.000000,"ym00411":0.000000,"bs00202":"C3","bs00203":"3-C","bs00205":"","bs00102":"多层测试","st00102":"个","ym00301":"","_parentId":1},{"Id":3,"ym00402":"b32300e4-e647-4e48-944a-62e959142507","ym00403":"faf8af33-031e-4166-b377-b520388601f5","ym00404":"c3dec451-43db-4117-a4bb-2124fcb77c52","ym00405":1.000000,"ym00406":"","ym00408":"","ym00410":0.000000,"ym00411":0.000000,"bs00202":"B3","bs00203":"3-B","bs00205":"","bs00102":"多层测试","st00102":"个","ym00301":"","_parentId":1},{"Id":4,"ym00402":"b32300e4-e647-4e48-944a-62e959142507","ym00403":"f27d6129-2557-4b94-ad60-d26e55aaa331","ym00404":"c3dec451-43db-4117-a4bb-2124fcb77c52","ym00405":1.000000,"ym00406":"","ym00408":"","ym00410":0.000000,"ym00411":0.000000,"bs00202":"A3","bs00203":"3-A","bs00205":"","bs00102":"多层测试","st00102":"个","ym00301":"","_parentId":1}],"footer":[{"bs00202":"sss"}]}
这和官方给的demo中的json数据结构一样，但是不显示。去掉外层的total和rows的话，显示但不分层
@亦有哭亦有笑: 不清楚。。可能版本不一样吧。。你先把你补充问题说的那个错误解决掉吧。打断点调试看看。 undefined is not a function 是执行了某个未赋值的函数变量
