treegrid 收缩问题

wankaiss

json :
{"total":86,"data":
[
{"ParentTaskUID":"-1","Name":"xxx","isLeaf":false,"Start":"2007-01-01T00:00:00","_level":1,"Critical":0,"Finish":"2007-01-10T00:00:00","PercentComplete":0,"Milestone":0,"OutlineLevel":1,"Summary":1,"UID":"1","Duration":8,"PredecessorLink":[],"OutlineNumber":"1"},
{"ParentTaskUID":"1","Name":"asd","isLeaf":true,"Start":"2007-01-01T00:00:00","_level":2,"Critical":0,"Finish":"2007-01-01T23:23:59","PercentComplete":30,"Milestone":0,"Summary":0,"UID":"2","Duration":1,"PredecessorLink":[],"OutlineNumber":"1.1","OutlineLevel":2}
]
}

随便做了个测试下,
点击xxx前面的减号,下面的明细怎么不会收缩?

dforce

你用的是什么控件
用你这数据，本地测试treegrid下可以收缩展开
