UWP 中的 ContentDialog，错误的滚动行为

Question

我特意用一个高大的 StackPanel 创建了这个 ContentDialog，但即使内容在 ScrollViewer 中，当它没有足够的空间时内容也会被剪裁 space。那里发生了什么？

<ContentDialog x:Name="ContentDialog">
    <ScrollViewer>
        <StackPanel>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
        </StackPanel>
    </ScrollViewer>
</ContentDialog>

但是，页面中的相同内容会正确显示滚动条。

因为ScrollViewer的高度设置为"Auto"。尝试将其绑定到内容对话框高度：

 <ContentDialog x:Name="ContentDialog">
    <ScrollViewer Height="{Binding ActualHeight, ElementName=ContentDialog}"  >
        <StackPanel>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
            <Button>Hola</Button>
        </StackPanel>
    </ScrollViewer>
</ContentDialog>

我改变主意了，对不起，我发现我现在错了！完美的解决方案是，

"modify the VerticalScrollBarVisibility Value Disabled to Auto"不需要！

我和你有同样的问题，我在bing或google中搜索了很多结果。但都没有用。

不过哈哈，我找到了简单的搞定方法

乍一看是这样的： https://social.msdn.microsoft.com/Forums/windowsapps/en-US/9112c2fe-1d93-48c9-9638-815be8005b86/uwpwindows-10-uap-scrollviewer-in-contentdialog

but it useless too in my case. and i changed anther line and 搞定 it.

in the ScrollViewer Node, i modify the VerticalScrollBarVisibility Value Disabled to Auto and it 搞定.

我的英语很差，希望能帮到你。我的开发环境是win10版本10240

完整代码如下：

Answer 3

这是您拥有的另一个解决方案：标题、文本框和按钮以及 ListView。
您必须使用此内容模板修改默认的 ContentDialog 或创建新样式以在您的应用程序的任何 ContentDialog 中使用它：

<Style x:Key="MyCustomToolsContentDialog"
    TargetType="ContentDialog">
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="ContentDialog">
            <Border x:Name="Container">
                <Grid x:Name="LayoutRoot">
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto" />
                    </Grid.RowDefinitions>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="Auto" />
                    </Grid.ColumnDefinitions>
                    <Border x:Name="BackgroundElement"
                            Background="{TemplateBinding Background}"
