如何在AdvancedDataGrid中获取标题列的列索引

问题描述

当用户单击标题时，我想知道AdvancedDataGrid中标题的列索引-左键单击还是右键单击.

I want to know column index of header in AdvancedDataGrid when a user clicks on header - either left click or right click.

推荐答案

AdvancedDataGrid调度headerRelease事件.此事件具有从零开始的 columnIndex 属性

AdvancedDataGrid dispatches a headerRelease event when you click on its header. This event has a zero based columnIndex property.

但是有一个问题:仅当单击的列是可排序的，并且数据提供程序支持排序.

There is one problem though: The headerRelease event is dispatched only if the clicked column is sortable and the data provider supports sorting.

<mx:AdvancedDataGrid headerRelease="handleHeaderClick(event)">
  <!-- Columns and stuff -->
</mx:AdvancedDataGrid>
<mx:Script>
  <![CDATA[

    private function handleHeaderClick(event:AdvancedDataGridEvent):void
    {
      var index:Number = event.columnIndex;
    }

  ]]>
</mx:Script>
