Question

为什么这不起作用： -

<toolkit:Accordion x:Name="___No_Name_"  Margin="0"  SelectionMode="OneOrMore" HorizontalAlignment="Stretch" VerticalAlignment="Top" Width="{Binding ActualWidth, ElementName=grid}"
                       >
        <toolkit:AccordionItem Header="Welcome" Margin="10,0" IsSelected="True" >
             <TextBlock Margin="3" TextWrapping="Wrap" Text="This site was created using FMT. This is a great system that allows anyone This site was created using FMT. This is a great system that allows anyone This site was created using FMT. This is a great system that allows anyone This site was created using FMT. This is a great system that allows anyone " FontFamily="Verdana" FontSize="13.333" Foreground="#FF033C68"/>
        </toolkit:AccordionItem>
        <toolkit:AccordionItem Header="Family news" Margin="10,0" />
        <toolkit:AccordionItem Header="Random photos" Margin="10,0" />
        <toolkit:AccordionItem Header="News articles" Margin="10,0" />
    </toolkit:Accordion>

我只能看到第1行。其余内容将被剪裁。为什么即使我对文本块进行换行，高度也不会自动设置？为什么这种控制会如此骚扰我？我做错了什么？为什么我无法通过此控件获得正常的预期行为？

即使这个最简单的标记也行不通。

除非TextBlock也设置TextBlock，否则Width中的文字不会换行。

我采用了“最简单的标记”，将Width=1000添加到TextBlock，文字按照我的预期包装。
