Flex datagrid headerColor style is not working....

Question

Hello guys. I am trying to change the datagrid header color by editing headerColor style. I could change the font size, font family...etc except the headerColor. Would someone help me about it? Thanks a lot.

My code

Mxml

<mx:DataGrid id="dataGrid" creationComplete="dataGrid_creationCompleteHandler(event)" dataProvider="{cityinfoResult3.lastResult}">
<mx:columns>
<mx:DataGridColumn headerText="Detail" dataField="detail"/>
<mx:DataGridColumn headerText="Name" dataField="name"/>
</mx:columns>
</mx:DataGrid>

Style

#dataGrid{
headerColors: #ff6600;    //everything works except this one. The color can't be                  
                          //changed?
rollOverColor: #33ccff;
textRollOverColor: #ffffff;
iconColor: #ff0000;
fontFamily: Arial;
fontSize:12;
dropShadowEnabled: true;
alternatingItemColors: #330099, #0000cc;
color: #ffffff;
borderColor: #ffffff;
}

Answer 1

headerColors needs an array of 2 items in order to draw a gradient. If you want a solid color, I bet something likethis would work:

headerColors: #ff6600, #ff6600 ; 

Answer 2

In Flex's CSS, you don't want the [] brackets around your values (though you would want them if you were doing this in straight-up ActionScript).

This should do the trick:

headerColors: #ff6600, #ff6600;
