AdvancedDataGrid自定义排序问题
之前在DataGrid写了一个排序方法，public function sortList(colName:String,sortType:String):void{
var sortField:SortField;
this.colName = colName;
if(sortType=="desc"){
sortField = new SortField(colName);
sortField.descending = true;
}
if(sortType=="asc"){
sortField = new SortField(colName);
sortField.descending = false;
}
var sort:Sort = new Sort();
sort.fields = [sortField];
dpFlat.sort = sort;
dpFlat.refresh();
}
很好用，但是在AdvancedDataGrid中，这个方法就不好使了。
我的想法是，在AdvancedDataGrid中，不打乱分组，然后对某一列进行排序，应该如何实现？请赐教
