概念上,Panorama控件是一个ItemPresenter(它继承自ItemsPresenter),即您可以将ItemsSource绑定到包含重复您的PanoramaItems的项目的列表.

要渲染PanoramaItem,您必须提供Panorama.HeaderTemplate和Panorama.ItemTemplate的模板.模板内的DataContext是代表PanoramaItem的viewmodel.如果此viewmodel包含项目列表,您现在可以使用它来生成您正在寻找的ListBoxes.

以下是样本……

编辑 – 添加其他第一个面板

最后,我明白了你想要实现的目标！但是,您仍然无需执行任何代码！你只需要一个模板……对于这个Blend确实可以帮到你,因为它可以让你为一个现有的控件提取模板……好的,这里是变化.

首先,我向Mainviewmodel添加了一个新属性来显示一些数据：

#region [MainPageProperty]

public const string MainPagePropertyPropertyName = "MainPageProperty";
private string _mainPageProperty = "Facilisi faucibus habitant inceptos interdum lobortis nascetur pharetra placerat pulvinar sagittis senectus sociosqu";

public string MainPageProperty {
    get {
        return _mainPageProperty;
    }
    set {
        if (_mainPageProperty == value) {
            return;
        }

        _mainPageProperty = value;
        RaisePropertyChanged(MainPagePropertyPropertyName);
    }
}

#endregion

然后我使用Blend获取Panorama控件的模板并将其插入控件：Panorama元素.

<controls:Panorama.Template>
    <ControlTemplate TargetType="controls:Panorama">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="auto"/>
                <RowDefinition Height="*"/>
            </Grid.RowDefinitions>
            <controlsPrimitives:PanningBackgroundLayer x:Name="BackgroundLayer" HorizontalAlignment="Left" Grid.RowSpan="2">
                <Border x:Name="background" Background="{TemplateBinding Background}" CacheMode="BitmapCache"/>
            </controlsPrimitives:PanningBackgroundLayer>
            <controlsPrimitives:PanningTitleLayer x:Name="TitleLayer" CacheMode="BitmapCache" ContentTemplate="{TemplateBinding TitleTemplate}" Content="{TemplateBinding Title}" FontSize="187" FontFamily="{StaticResource PhoneFontFamilyLight}" HorizontalAlignment="Left" Margin="10,-76,9" Grid.Row="0"/>
            <controlsPrimitives:PanningLayer x:Name="ItemsLayer" HorizontalAlignment="Left" Grid.Row="1">
                <StackPanel Orientation="Horizontal">
                    <controls:PanoramaItem Header="Main panel" Width="432">
                        <TextBlock Text="{Binding ElementName=LayoutRoot,Path=DataContext.MainPageProperty}" TextWrapping="Wrap"/>
                    </controls:PanoramaItem>
                    <ItemsPresenter x:Name="items"/>
                </StackPanel>
            </controlsPrimitives:PanningLayer>
        </Grid>
    </ControlTemplate>
</controls:Panorama.Template>

这里有两个技巧,首先我插入一个StacPanel,允许在controlPrimitives下面有多个元素：PanningLayer,名称为ItemsPanel.在这个StackPanel中,我移动了ItemsPresenter并添加了另一个PanoramaItem.但有一件重要的事情是设置PanoramaItem的Width属性,否则面板将扩展到所需的房间.

另一个技巧是,为了访问DataContext,我必须在Binding中使用ElementName.

希望这能展示MVVM和模板的力量！
