            width="300"
            rowCount="8">
        <mx:columns>
            <mx:DataGridColumn dataField="c1"

            <mx:DataGridColumn dataField="c2"

        </mx:columns>
    </mx:DataGrid>

</mx:Application>

View source is enabled in the following example.

You can also set the sortArrowSkin style in an external .CSS file or <mx:Style /> block, as shown in the following snippet:

<mx:Style>
    DataGrid {
        sortArrowSkin: Embed("assets/thumb_down.png");
    }
</mx:Style>

Or, you can set the sortArrowSkin style using ActionScript, using the following snippet:

<mx:Script>
    <![CDATA[
        [Embed("assets/thumb_down.png")]
        private var thumbDownIcon:Class;

        private function init():void {
            dataGrid.setStyle("sortArrowSkin", thumbDownIcon);
        }
    ]]>
</mx:Script>
