Devsena updated FLEX-35222:
---------------------------
    Attachment: DataGridSortingExample.zip

I'm presently working on a very basic implementation to DataGrid sorting. This still in it's initial stage but it able to sort columns at runtime. Requested Peter or any one to review the source and advise if we're on right track and if we need to continue our effort. I'm attaching herewith the example project (DataGridSortingExample.zip) that sorts, and following are a few custom classes which we've created for this goal. 

*PNDataGridButtonBarButtonItemRenderer:* The class extended by _ButtonBarButtonItemRenderer_ which creates the button component as column header and listen to it's click event. The class override to pass our custom events with requisite information; along with showing an icon for ascending/descending sort position. 

*PNDataGridColumnSorter:* A bead which can be added to DataGrid component class, and should supply with same field references as we supply for _PNDataProviderChangeNotifier_ class - *sourceID*, *propertyName* - the class reference holding the ArrayList collection to DataGrid, and the field name for the ArrayList respectively. The class catches the event fired by _PNDataGridButtonBarButtonItemRenderer_, sort the array per column index (from which column the event fired), updates the main ArrayList and also re-renders the DataGrid. 

*Known issues:*
# Sorting icon remains to the column once sorted. It suppose to get hidden when another column sorted

Let me your views.
