Howdy,

Pretty new to AS3, but thought I'd see if you can help me out here.

I have a datagrid with some numeric columns. I created an item itemRenderer to
add commas to those columns. But now the columns won't sort numerically. I
saw some code that I have attached, the problem is, the code references the
columns by name "testvalue." and I need it to work generically, no matter what
column I am sorting.

Help?

<?xml version=?1.0? encoding=?utf-8??>
<mx:Application xmlns:mx=?http://www.adobe.com/2006/mxml? layout=?absolute?>
<mx:XMLList id=?testdata?>
<testdata> <name>a</name> <testvalue>1</testvalue> </testdata>
<testdata> <name>aa</name> <testvalue>11</testvalue> </testdata>
