You could also extend DataGrid and override the selectItem method like so:

override protected function selectItem(item:IListItemRenderer, shiftKey:Boolean, ctrlKey:Boolean, transition:Boolean = true):Boolean
{
    return super.selectItem(item, shiftKey, true, transition )
}

Less code and less likely to have impact on other elements that might be listening for that MouseEvent.
