用属性绑定标签

在我的WPF应用程序页面上，我有两个绑定1. 作为可观察集合的项列表2. 使用绑定

在标签上显示一些值

我的类结构像这样

 public DbVersionModel DbVersion { get; set; }
  public ObservableCollection<BookStore> StoreCollection
  { get { return thisApp.app_Stores; } }

public class DbVersionModel : INotifyPropertyChanged
{
    private int _LocalVersion { get; set; }
    private int _ServerVersion { get; set; }
    private int _ActiveStores { get; set; }
    private string _LastModifiedLocal { get; set; }
    private string _LastModifiedServer { get; set; }
    public event PropertyChangedEventHandler PropertyChanged;
    private void NotifyChange(PropertyChangedEventArgs e)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, e);
    }
    public int LocalVersion
    {
        get { return _LocalVersion; }
        set
        {
            _LocalVersion = value;
            NotifyChange(new PropertyChangedEventArgs("LocalVersion"));
        }
    }
    public int ServerVersion
    {
        get { return _ServerVersion; }
        set
        {
            _ServerVersion = value;
            NotifyChange(new PropertyChangedEventArgs("ServerVersion"));
        }
    }
    public int ActiveStores
    {
        get { return _ActiveStores; }
        set
        {
            _ActiveStores = value;
            NotifyChange(new PropertyChangedEventArgs("ActiveStores"));
        }
    }
    public string LastModifiedLocal
    {
        get { return _LastModifiedLocal; }
        set
        {
            _LastModifiedLocal = value;
            NotifyChange(new PropertyChangedEventArgs("LastModifiedLocal"));
        }
    }
    public string LastModifiedServer
    {
        get { return _LastModifiedServer; }
        set
        {
            _LastModifiedServer = value;
            NotifyChange(new PropertyChangedEventArgs("LastModifiedServer"));
        }
    }
}   public ManagePage()
{
    InitializeComponent();
    setContext();
}
private void setContext()
{
     try
    {
       DbVersionModel db_version = new DbVersionModel();
        db_version.LastModifiedServer = //set with value;
        db_version.ServerVersion = //set with value;
        db_version.LocalVersion = //set with value;
        db_version.LastModifiedLocal = //set with value;
        db_version.ActiveStores = //set with value;
        this.DbVersion = db_version;
    }
    catch
    {
    }
}

xaml像这样

                            <ColumnDefinition ></ColumnDefinition>

                            <RowDefinition Height="Auto"></RowDefinition>
                            <RowDefinition Height="Auto"></RowDefinition>
                            <RowDefinition Height="Auto"></RowDefinition>
                            <RowDefinition Height="Auto"></RowDefinition>
                            <RowDefinition Height="Auto"></RowDefinition>
                            <RowDefinition Height="Auto"></RowDefinition>
                        </Grid.RowDefinitions>
                        <!--//    -->
                        <Label Content="Active stores[Local]"  Grid.Column="0" Grid.Row="0" ></Label>
                        <Label Content="{Binding Source=DbVersion, Path=ActiveStores}"  Grid.Column="1" Grid.Row="0" ></Label>
                        <Label Content="Current version [Local]"  Grid.Column="0" Grid.Row="1" ></Label>
                        <Label Content="{Binding Source=DbVersion, Path=LocalVersion}"  Grid.Column="1" Grid.Row="1" ></Label>
                        <Label Content="Curretn Version [Server]"  Grid.Column="0" Grid.Row="2" ></Label>
                        <Label Content="{Binding Source=DbVersion, Path=ServerVersion}"  Grid.Column="1" Grid.Row="2" ></Label>
                        <Label Content="Last modified  [Local]"  Grid.Column="0" Grid.Row="3" ></Label>
                        <Label Content="{Binding Source=DbVersion, Path=LastModifiedLocal}"  Grid.Column="1" Grid.Row="3" ></Label>
                        <Label Content="Last  modified [Server]"  Grid.Column="0" Grid.Row="4" ></Label>
                        <Label Content="{Binding Source=DbVersion, Path=LastModifiedServer}"  Grid.Column="1" Grid.Row="4" ></Label>
                        <StackPanel   Grid.Column="0" Grid.ColumnSpan="5" Grid.Row="6" HorizontalAlignment="Center">
                            <Button Name="btnSync" Content="Sync stores" Height="30" Click="btnSync_Click" Style="{StaticResource ActionButtons}"></Button>
                        </StackPanel>
                    </Grid>
    </ScrollViewer>

还有一个ItemsControl它像这样被加载并且绑定工作正常

    <ItemsControl Name="StoreListView" ItemsSource="{Binding StoreCollection}" Margin="5" VirtualizingStackPanel.IsVirtualizing="True"
                    VirtualizingStackPanel.VirtualizationMode="Recycling"  >

但是ObservableCollection列表绑定是好的，但是标签绑定不起作用。我该如何解决这个问题?

如何根据类的属性设置标签绑定
