How to add an empty row in datagrid in wpf

WPF

I have a datagrid which is bound to a list in TwoWay path.
the default behavior of the enter key for the grid which i found is move down.

i used the following code to make the movement to the right

var element = e.OriginalSource as FrameworkElement;
if (e.Key == Key.Enter)
            {
                e.Handled = true;
                element.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
            }

But now the issue to my grid is that it does not add an empty row to for the new item. It is not making any new item place holder.

1) Is there a way to add manually a new empty row in DataGrid in wpf or
2) can i use any method to make my grid to be able to add a new row or move to the next new row after the last focusable column?
thank you in advance.
