In this tutorial, we will create the standard Silverlight ListBox will be customized to be functionally similar to a ListBox you would find on a Mac.

The XAML for this tutorial contains a custom style that we use to disable the scrollbar:

<UserControl x:Class="CustomListBox.Page"
    Width="400" Height="300">
    <Grid x:Name="LayoutRoot" Background="White">
            <Style x:Key="ListBoxStyle1" TargetType="ListBox">
                <Setter Property="Template">
                        <ControlTemplate TargetType="ListBox">
                            <Grid x:Name="LayoutRoot">
                                <Border Padding="5" BorderBrush="#000000" BorderThickness="1" Background="#ffffff" CornerRadius="0">
                                    <ScrollViewer x:Name="ScrollViewer" VerticalScrollBarVisibility="Hidden" Padding="{TemplateBinding Padding}" Background="{TemplateBinding Background}" BorderBrush="Transparent" BorderThickness="0">
                                        <ItemsPresenter />
        <StackPanel Margin="4" HorizontalAlignment="Left">
            <RepeatButton Width="200" Height="22" Click="Up_Click">
                <Polygon Points="5,0 10,10 0,10 5,0" Fill="#222222" />
            <ListBox x:Name="listbox" Width="200" Height="150" Style="{StaticResource ListBoxStyle1}">
                <ListBoxItem Content="Item 1" />
                <ListBoxItem Content="Item 2" />
                <ListBoxItem Content="Item 3" />
                <ListBoxItem Content="Item 4" />
                <ListBoxItem Content="Item 5" />
                <ListBoxItem Content="Item 6" />
                <ListBoxItem Content="Item 7" />
                <ListBoxItem Content="Item 8" />
                <ListBoxItem Content="Item 9" />
                <ListBoxItem Content="Item 10" />
                <ListBoxItem Content="Item 11" />
                <ListBoxItem Content="Item 12" />
            <RepeatButton Width="200" Height="22" Click="Down_Click">
                <Polygon Points="5,10 10,0 0,0 5,10" Fill="#222222" />

In XAML, just apply the custom style and populate it with some test data.  There are also two repeat buttons, an up and down that will handle the scrolling for us:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace CustomListBox
    public partial class Page : UserControl
        public Page()

        private void Up_Click(object sender, RoutedEventArgs e)
            if (listbox.Items.Count > 0)
                int newIndex = listbox.SelectedIndex - 1;

                if (newIndex < 0)
                    newIndex = 0;
                listbox.SelectedIndex = newIndex;

        private void Down_Click(object sender, RoutedEventArgs e)
            if (listbox.Items.Count > 1)
                int newIndex = listbox.SelectedIndex + 1;

                if (newIndex >= listbox.Items.Count)
                    newIndex = listbox.Items.Count - 1;
                listbox.SelectedIndex = newIndex;
