Question

手风琴项目Visibility属性可以这样绑定：

<layoutToolkit:Accordion x:Name="MyAccordion">
    <layoutToolkit:AccordionItem Visibility="{Binding IsVisible, Converter={StaticResource VisibilityConverter}}">
        ...
    </layoutToolkit:AccordionItem>
</layoutToolkit:Accordion>

但是在使用Accordion.ItemTemplate时如何绑定它？

<layoutToolkit:Accordion ItemsSource="{Binding AcordionItems}" x:Name="MyAccordion">
    <layoutToolkit:Accordion.ItemTemplate>
        <DataTemplate>
            ...
        </DataTemplate>
    </layoutToolkit:Accordion.ItemTemplate>
    <layoutToolkit:Accordion.ContentTemplate>
        <DataTemplate>
            ...
        </DataTemplate>
    </layoutToolkit:Accordion.ContentTemplate>
</layoutToolkit:Accordion>

我可以将IsVisible绑定到DataTemplate中的元素，但是会显示一个空的折叠项。我需要能够显示/隐藏整个手风琴项目。

我最终使用StackPanel和多个Accordions：

<StackPanel Orientation="Vertical">
    <ItemsControl ItemsSource="{Binding AcordionItems}">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <StackPanel Orientation="Vertical"/>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>

        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <layoutToolkit:Accordion Visibility="{Binding IsVisible, Converter=
                    {StaticResource VisibilityConverter}}">
                    <layoutToolkit:AccordionItem>
                        ...
                    </layoutToolkit:AccordionItem>
                </layoutToolkit:Accordion>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</StackPanel>

如何在Silverlight中使用Accordion.ItemTemplate时绑定AccordionItem可见性？
