title: AS3 Datagrid multiple selection
body: <p>I am working with Flash AS3 (not Flex) .
  I have a datagrid with <strong>"allowMultipleSelection = true";</strong>
  I want get and store the selected rows in my Data Base only when the row selection is completed using a button. (I don't want use "ListEvent.ITEM_CLICK" because a row can be selected and removed from the selection using the CTRL key)</p>
  
  <p>How can I retrieve the selected rows in the datagrid?</p>
