Expander控件样式：

前端界面：

 <Expander Margin="30,0,0,0" IsExpanded="True">
                    <Expander.Header>
                        <TextBlock Text="设备类型" Foreground="White"/>
                    </Expander.Header>
                    <Expander.Content>
                        <ListBox Margin="10,0,0,0" VerticalAlignment="Stretch" Name="AssetListBox" ItemsSource="{Binding }"
                                 Style="{StaticResource ListBoxAsset}" SelectionChanged="AssetListBox_SelectionChanged">
                            <ListBox.ItemTemplate>
                                <DataTemplate>
                                    <TextBlock Margin="2" Foreground="White" Text="{Binding Name}"/>
                                </DataTemplate>
                            </ListBox.ItemTemplate>
                        </ListBox>
                    </Expander.Content>
                </Expander>

后台cs代码：建立一个类，绑定数据

 public class Test
    {
        public string Name { get; set; }
        public int ID { get; set; }
    }

private void UserControl_Loaded(object sender, RoutedEventArgs e)        

{     

         List<Test> list = new List<Test>();
            for (int i = 0; i < 10; i++)
            {
                Test info = new Test();
                info.ID = i;
                info.Name = i.ToString();
                list.Add(info);
            }
            AssetListBox.DataContext = list;

 }

如下图所示：
