C# LongListSelector未绑定数据数组Windows Phone 8

我正在使用LongListSelector并尝试绑定数组。但没有显示任何数据。以下是我的代码，请让我知道我做错了什么

XAML

在类中有一些属性，在xaml中有不同的绑定

 <phone:LongListSelector Name="peopleLongListSelector"   
                                            ItemsSource="{Binding ComponentData}"
                                            GroupHeaderTemplate="{StaticResource LongListSelectorGroupHeaderTemmplate}"
                                            ItemTemplate="{StaticResource LongListSelectorItemTemplate}"
                                            HideEmptyGroups ="true" 
                                            IsGroupingEnabled ="true" 
                                            LayoutMode="List">
            </phone:LongListSelector>
            <DataTemplate x:Key="LongListSelectorGroupHeaderTemmplate">
            <Border Background="Transparent" Padding="5">
                <Border Background="{StaticResource PhoneAccentBrush}" BorderBrush="{StaticResource PhoneAccentBrush}" BorderThickness="2"  
                                           Width="62" Height="62" Margin="0,0,18,0"                  
                                            HorizontalAlignment="Left">
                    <TextBlock Text="{Binding Name}" 
                                                   Foreground="{StaticResource PhoneForegroundBrush}" 
                                                   FontSize="48"
                                                   Padding="6"
                                                   FontFamily="{StaticResource PhoneFontFamilySemiLight}"
                                                   HorizontalAlignment="Left"
                                                   VerticalAlignment="Center"/>
                </Border>
            </Border>
        </DataTemplate>    
        <DataTemplate x:Key="LongListSelectorItemTemplate">
            <StackPanel Orientation="Horizontal" Margin="4,4">

            </StackPanel>

在Listview LongListSelectorGroupHeaderTemplate中，我是组件类的绑定名称属性。即使是这样，也没有被绑定。。。？？你有没有在一个示例应用程序中试用过它？你有项目吗？我有项目和多个组件。你试过这个密码了吗。这对您有用吗？您正在异步获取数据-我猜您的LLS没有更新-您有绑定，但没有INotifyPropertyChanged。尝试实现该接口并在PropertyChanged上运行。或者可能使用ObservableCollection而不是ComponentData数组。

  public class Component
    {
        public string Guid {get; set;}
        public string Name{get; set;}
        public Item[] Items{get; set;}
    }



    public class Item
        {
           public string Title{get; set;}
            public string Subtitle{get; set;}
            public string Date{get; set;}
         }

       public class MainLstViewModel : BaseViewModel
        {
             private Component[] ComponentData;
             public MainLstViewModel()
             {
               ComponentData = Proxy.GetDataAsync();
             }
        }

 <phone:LongListSelector Name="peopleLongListSelector"   
                                            ItemsSource="{Binding ComponentData}"
                                            GroupHeaderTemplate="{StaticResource LongListSelectorGroupHeaderTemmplate}"
                                            ItemTemplate="{StaticResource LongListSelectorItemTemplate}"
