[flexcoders] Datagrid - case-insensitive sort

[Paul Booth]

Hi,
When I click on a column header to sort a datgrid column the sort is case
sensitive
e.g. the values aa, AA, bb, BB are displayed as

AA
BB
aa
bb

I can't find a way to tell the Datagrid (or DatagridColumn) to sort in a
case-insensitive manner. Can someone please enlighten me?

Thanks,

Paul.
