Thanks all for the suggestions! "Will using the sortOptions property on a DataGridColumn do what you want?"
Hmm. I don't think that is supported in Flex 3 (http://livedocs.adobe.com/flex/3/langref/mx/controls/dataGridClasses/DataGridColumn.html), although that would have been nice. Both of the other solutions looks pretty promising. I will probably do something like what Adrian suggested, in order to keep things as simple as possible. Perhaps I will post a feature-request on JIRA sometime soon and see if it is something they could add easily :) Take care, Keith
