Description

1. Drag and drop a datagrid to stage and set backgroundColor to one of the columns
or use the following MXML

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:DataGrid x="10" y="10">
<mx:columns>
<mx:DataGridColumn headerText="Column 1" dataField="col1" backgroundColor="0x555555"/>
<mx:DataGridColumn headerText="Column 2" dataField="col2"/>
<mx:DataGridColumn headerText="Column 3" dataField="col3"/>
</mx:columns>
</mx:DataGrid>

</mx:Application>

2. Run the swf

You will get the following runtime error
