Просто используйте sortByColumn
метод:
var columnIndexes:Vector.<int> = Vector.<int>([ 0 ]);
dataGrid.sortByColumns(columnIndexes, true);
Вот полный пример:
DataGridSort.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
