如何在XAML中设置绑定上下文到其他类?

我有一段代码,我正试图绑定到一个名为BandInfoRepository的类。cs,它与名为PaginaB的XAML位于同一文件夹中。我看不到VisualStudio上没有显示任何语法错误,但仍然没有显示文本(我添加backgroundColor只是为了查看标签是否正在显示,但文本没有显示)。

也许有必要指出我使用的是syncfusion的listview。

           <syncfusion:SfListView x:Name="listView"
                ItemsSource="{Binding Source={local2:BandInfoRepository}, Path=BandInfo}" 
                ItemSize="100"
                AbsoluteLayout.LayoutBounds="1,1,1,1" 
                AbsoluteLayout.LayoutFlags="All" >
                <syncfusion:SfListView.ItemTemplate>
                    <DataTemplate>
                        <Grid Padding="10">
                            <Grid.RowDefinitions>
                                <RowDefinition Height="0.4*" />
                                <RowDefinition Height="0.6*" />
                            </Grid.RowDefinitions>
                            <Label Text="{Binding Source={local2:BandInfoRepository}, Path=BandName}"
                                BackgroundColor="Olive"
                                FontAttributes="Bold" 
                                TextColor="Black" 
                                FontSize="20" />
                            <Label Grid.Row="1"
                                BackgroundColor="Navy"
                                Text="{Binding Source={local2:BandInfoRepository}, Path= BandDescription}" 
                                TextColor="Black" 
                                FontSize="14"/>
                        </Grid>
                    </DataTemplate>
                </syncfusion:SfListView.ItemTemplate>
            </syncfusion:SfListView>

这是BandInfoRepository。cs文件:

public class BandInfoRepository
{
    private ObservableCollection<BandInfo> bandInfo;

    public ObservableCollection<BandInfo> BandInfo
    {
        get { return bandInfo; }
        set { this.bandInfo = value; }
    }

    public BandInfoRepository()
    {
        GenerateBookInfo();
    }

    internal void GenerateBookInfo()
    {
        bandInfo = new ObservableCollection<BandInfo>();
        bandInfo.Add(new BandInfo() { BandName = "Nirvana", BandDescription = "description" });
        bandInfo.Add(new BandInfo() { BandName = "Metallica", BandDescription = "description" });
        bandInfo.Add(new BandInfo() { BandName = "Frank Sinatra", BandDescription = "description" });
        bandInfo.Add(new BandInfo() { BandName = "B.B. King", BandDescription = "description" });
        bandInfo.Add(new BandInfo() { BandName = "Iron Maiden", BandDescription = "description" });
        bandInfo.Add(new BandInfo() { BandName = "Megadeth", BandDescription = "description" });
        bandInfo.Add(new BandInfo() { BandName = "Darude", BandDescription = "description" });
        bandInfo.Add(new BandInfo() { BandName = "Coldplay", BandDescription = "description" });
        bandInfo.Add(new BandInfo() { BandName = "Dream Evil", BandDescription = "description" });
        bandInfo.Add(new BandInfo() { BandName = "Pentakill", BandDescription = "description" });
    }
}
