XAML 内容对话框不滚动

在UWP中，ContentDialog只会调整到一定的大小，然后内容会被剪切-而不是滚动。如果我在内容中包含一个ScrollViewer，它只会随着内容的无限增长而永远不会滚动。

由于我在其他地方找不到这个问题的解决方案，下面是我的解决方案：
从https://msdn.microsoft.com/en-us/library/windows/apps/mt299120.aspx复制ContentDialog的默认样式，并将ScrollViewer的属性从：

<ScrollViewer x:Name="ContentScrollViewer"
                    HorizontalScrollBarVisibility="Disabled"
                    VerticalScrollBarVisibility="Disabled"

到

<ScrollViewer x:Name="ContentScrollViewer"
                    HorizontalScrollBarVisibility="Auto"
                    VerticalScrollBarVisibility="Auto"

听起来很简单，但是我花了太多时间调试可视化树才弄明白这一点...
以下是应用于您希望可滚动的ContentDialog的完整样式：

<!-- Default style for Windows.UI.Xaml.Controls.ContentDialog -->
        <Style TargetType="ContentDialog" x:Key="ScrollableContentDialogStyle">
            <Setter Property="Foreground" Value="{ThemeResource SystemControlPageTextBaseHighBrush}" />
            <Setter Property="Background" Value="{ThemeResource SystemControlBackgroundChromeMediumLowBrush}" />
            <Setter Property="HorizontalAlignment" Value="Center" />
            <Setter Property="VerticalAlignment" Value="Top" />
            <Setter Property="IsTabStop" Value="False" />
            <Setter Property="MaxHeight" Value="{ThemeResource ContentDialogMaxHeight}" />

不确定在最新的SDK中是否有一些相关的增强，但至少现在可以使用（在对话框中显示长文本的非常简单的方法，而不需要任何新的XAML）：

async Task ShowDialogAsync(string title, string text)
{
    var dialog = new ContentDialog()
    {
        Title = title,
        Content = new ScrollViewer()
        {
            Content = new TextBlock() { Text = text },
        },
        CloseButtonText = "ok"
    };

    await dialog.ShowAsync();
}

您必须使用此内容模板修改默认的ContentDialog，或创建新样式以在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}"

对于WinUI 3（Windows应用程序开发工具包）：
这个解决方案与@Markus Hütter的解决方案相似但稍有不同。
首先，请注意，一个简单的方法来获得复制和粘贴的默认模板，如@Markus Hütter所建议的，是将Style="{StaticResource DefaultContentDialogStyle}"添加到您的内容对话框，右键单击，并选择转到定义。您可以将样式设置保留在您的内容对话框中，稍后用新的样式名称替换样式名称（下面讨论）。
在我的应用程序中（我假设默认情况下，在所有WinUI 3应用程序中），样式存在于generic.xaml中。
将整个样式复制到App.xamlResourceDictionary中，并将样式中的ScrollViewerDisabled设置更改为Auto，如下所示：

<ScrollViewer x:Name="ContentScrollViewer" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" ZoomMode="Disabled" IsTabStop="False">

此外，为新的自定义样式指定一个唯一的名称，例如：

<Style x:Key="MyCustomScrollableContentDialogStyle" TargetType="ContentDialog"> ...

注意，如上所述，您的ContentDialog需要使用Style="{StaticResource MyCustomScrollableContentDialogStyle}"引用新样式名称
这是有点长，但这是我的最终风格：

<!-- Derived from Default style for Windows.UI.Xaml.Controls.ContentDialog. Scrollviewer settings were changed in this version -->
        <Style x:Key="SSXScrollableContentDialogStyle" TargetType="ContentDialog">
            <Setter Property="Foreground" Value="{ThemeResource ContentDialogForeground}" />
            <Setter Property="Background" Value="{ThemeResource ContentDialogBackground}" />
            <Setter Property="BorderThickness" Value="{ThemeResource ContentDialogBorderWidth}" />
            <Setter Property="BorderBrush" Value="{ThemeResource ContentDialogBorderBrush}" />
            <Setter Property="IsTabStop" Value="False" />
            <Setter Property="PrimaryButtonStyle" Value="{ThemeResource DefaultButtonStyle}" />
            <Setter Property="SecondaryButtonStyle" Value="{ThemeResource DefaultButtonStyle}" />
            <Setter Property="CloseButtonStyle" Value="{ThemeResource DefaultButtonStyle}" />
            <Setter Property="CornerRadius" Value="{ThemeResource OverlayCornerRadius}" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ContentDialog">
                        <Border x:Name="Container">
