silverlight - 当外部 Accordian 中的项目过多时，内部 Accordion 项目出现扩展问题

Question

我有以下使用accrodian的xaml代码。基本上问题是我正在使用两个嵌套在另一个中的手风琴。两者都被 ScrollViewer 屏蔽。如果外部手风琴中的项目超过 14 个，则扩展的内部项目不可见，这意味着它正在扩展，但由于没有空间，它不可见。

<toolkit:AccordionItem x:Name="test2" Style="{StaticResource ContentEditorAccordionItemStyle}" Header="{Binding LogicBlock, Source={StaticResource ResourceString}}" HorizontalAlignment="Stretch">
    <ScrollViewer BorderBrush="Red" BorderThickness="2" Grid.Row="3" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Style="{StaticResource ScrollViewerStyle}">
        <toolkit:Accordion Grid.Row="1"  x:Name="testnew" ItemsSource="{Binding DynamicContentBlocks.Source, Mode=TwoWay}" FontSize="10" BorderBrush="{x:Null}">

Answer 1

这是 Accordion 和 AccordionItem 的问题，我用 Expander 控件替换了 Accordion 并解决了问题...

Answer 2

请参考以下代码：

<Accordion>
     <ScrollViewer>
          <Accordion>
          </Accordion>
     <ScrollViewer>
</Accordion>
