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：
