 private void dataGrid1_KeyUp(object sender, KeyEventArgs e)
        {
            DependencyObject dep = (DependencyObject)e.OriginalSource;
            //here we find the Row is selected
            //then we check is the row last row

            while ((dep != null) && !(dep is DataGridRow) && !(dep is DataGridColumnHeader))
            {
                dep = VisualTreeHelper.GetParent(dep);
            }

            if (dep == null)
                return;

            if (dep is DataGridRow)
            {
                DataGridRow row= dep as DataGridRow;
                //untill here we find the selected row and here we check if it
                //the last row our focus go to next control after datagrid
               if (row.GetIndex() == dataGrid1.Items.Count - 1)
            {
                dataGrid1.MoveFocus(new TraversalRequest(FocusNavigationDirection.Down));
                dataGrid1.UnselectAll();
            }
            }
        }

set this event as key up of your datagrid . use this refrence too using System.Windows.Controls.Primitives . put datagrid and some other control to your window . when you get to last row it will change focuse to next control. i will occur when you rich last row because of this if (row.GetIndex() == dataGrid1.Items.Count - 1)

i use datagrid with fullrowselect as selection mode.if you want use datagrid with cell selection mode leave comment for me please.
