private void ChangeExpandDirection(object sender, RoutedEventArgs e)

    else if ((Boolean)ExpandUp.IsChecked)
        myExpander.ExpandDirection = ExpandDirection.Up;
    else if ((Boolean)ExpandLeft.IsChecked)
        myExpander.ExpandDirection = ExpandDirection.Left;
    else if ((Boolean)ExpandRight.IsChecked)
        myExpander.ExpandDirection = ExpandDirection.Right;

    //Expand myExpander so it is easier to see the effect of changing

}

Private Sub ChangeExpandDirection(ByVal Sender As Object, ByVal e As RoutedEventArgs)
    If (ExpandDown.IsChecked) Then
        myExpander.ExpandDirection = ExpandDirection.Down
    ElseIf (ExpandUp.IsChecked) Then
        myExpander.ExpandDirection = ExpandDirection.Up
    ElseIf (ExpandLeft.IsChecked) Then
        myExpander.ExpandDirection = ExpandDirection.Left
    ElseIf (ExpandRight.IsChecked) Then
        myExpander.ExpandDirection = ExpandDirection.Right
    End If
