In summary: How does one differentiate between a column which is sorting ascending and not sorting at all?
Detail: Prior to Flex3 there was a property of a DataGrid (sortIndex) which afforded one the ability to determine which column was the sort column. This property was removed in Flex 3's DataGrid. (perhaps because a single value is insufficient when multicolumn sorting is inuse) In flex3's datagrid: One can read the order of the columns by the order that the DataGridColumn items are returned in the datagrid's columns attribute. One can determine if any column is sorting descending by the sortDescending attribute of the individual DataGridColumn item being set to true. However if the column is NOT sorting at all OR if it is sorting ascending the value of sortDescending is false. How does one differentiate between a column which is sorting ascending and not sorting at all? Presumably in flex2 for single column sorting one could determine this with the datagrid's sortIndex property (typically either no column or one column would be the sort column), but with this attributes removal from dataGrid I'm not sure how to do this. Any hints appreciated!
