Flex 4 spark datagrid selected row change with tab

Question

I'm trying to change the selected row in a spark data grid when tabbing passed the last column. In other words, I'd like to highlighted row to follow the active cell.

Any ideas?

Thank You.

Do you want just to change the active row using Tab or should each Cell in a row be visited using Tab and after visiting the last one in a row the first cell of the next row should be selected? — Anton
Change the active row with Tab. Like the default behavior found in the MX datagrid. — jayron
This helps. Although it feels like going on a cruise to buy a wrist watch. Many thanks! — jayron
I have tried to extract only the code you need, but I can't do it. If you get it done, please answer your question here. — Anton

Here's how i went about it. I have my selectionChange and caretChange events on the grid doing the same function.

<s:DataGrid id="my_rates_grid" x="0" y="0" width="100%" height="100%"
                            creationComplete="my_rates_grid_creationCompleteHandler(event)"
                            editable="true" alternatingRowColors="[#FFFFFF, #e9f1f6]"
                            gridItemEditorSessionSave="my_rates_grid_gridItemEditorSessionSaveHandler(event)"
                            requestedRowCount="4"
                            selectionChange="my_rates_grid_selectionChangeHandler(event)"
                            caretChange="my_rates_grid_selectionChangeHandler(event)">

Then in that my_rates_grid_selectionChangeHandler function (note i had to change its param type to generic type Event)

protected function my_rates_grid_selectionChangeHandler(event:Event):void
        {
            if(my_rates_grid.editorRowIndex >= 0){
                trace("it's happening");
                my_rates_grid.setSelectedIndex(my_rates_grid.editorRowIndex);
            }


        }

so everytime i tabbed it would follow and the save feature captures my new values as well.
