I don't think you can use the sortCompareFunction that way...it needs a
function to process your data against.
We use a number of customized sorting functions on a number of our
fields via both sort.compareFunction as well as adg.sortCompareFunction,
though funny enough, the compareFunction is a bit different depending on
which way you are using it. If you are tying it to an ADG
sortCompareFunction, it takes two arguments while when using a Sort()
compareFunction, it takes three.
When trying to do an alphabetical sort (on the ADG), we do this:
public static function compareLastNames(name1:Object,
name2:Object):int
{
var newName1:String = name1.LastName + name1.FirstName +
name1.MiddleName;
var newName2:String = name2.LastName + name2.FirstName +
name2.MiddleName;
if (newName1.toLowerCase() < newName2.toLowerCase())
{
return -1;
}
else if (newName1.toLowerCase() > newName2.toLowerCase())
{
return 1;
}
else
{
return 0;
}
}
and when using a Sort() we do the very same logic but we have to add a
"fields" parameter into the method signature:
public static function compareLastNamesWithFields(name1:Object,
name2:Object, fields:Array = null):int
In this case, we've automatically set the fields array to null as we
never have any fields to pass in but without it, flex throws errors
(we've long thought this to be a bug).
Also note that these are public and static because we've abstracted them
into a class.
Hope this helps!

I just tested, this gives me a compiler error both on a ComboBox and

What are you doing that I'm not doing?

Will using the sortOptions property on a DataGridColumn do what you want?
