Flash Builder中不区分大小写的排序与AdvancedDatagrid头点击

阅读所有我能找到我采取了以下sortCompareFunction主题后...Flash Builder中不区分大小写的排序与AdvancedDatagrid头点击

private function value_sortCompareFunc(itemA:Object, itemB:Object):int { 
    return ObjectUtil.stringCompare(itemA.value, itemB.value, true); 
}

在DataGrid加载数据源已排序（不区分大小写）由后端数据库如下。

Ababa, Meaghan 
abadilla, Athena 
Adams, AJ Jordan 
.... 
.... 
Lin, Jia 
etc...

此时排序很好，不区分大小写。

但是，当用户单击此列的标题时，我会收到。

Lin, Jia 
Ababa, Meaghan 
abadilla, Athena 
Adams, AJ Jordan 
etc...

除了第一个名字，其余的似乎是正确排序的。难道我做错了什么？这是一个错误？

感谢，

约翰

Datgrid代码（我还没有把sortCompareFunction设置与其他α列还）....

你可以写在指定的列为sortable = false。然后，如果您点击标题，则不会有任何影响。请参阅下面的答案

<mx:AdvancedDataGrid id="myADG" width="100%" height="100%" dataProvider="{theModel.quiz_member_list}" 
        > 
    <mx:columns> 
     <mx:AdvancedDataGridColumn headerText="S.No" dataField="sNo" width="55" sortable="false" /> 
     <mx:AdvancedDataGridColumn headerText="Name" dataField="username" sortable="false" /> 
    </mx:columns> 
    </mx:AdvancedDataGrid>

但我确实希望在单击标题时对dg进行排序。我只是希望它不区分大小写。我在答案中错过了什么？问题是第一行出现故障。 – user278859
