ContentDialog doesn't scroll - xaml

Question

In UWP the ContentDialog resizes only to a certain size and then the content is clipped - not scrolled. If I include a ScrollViewer in the Content it just grows with its' contents indefinately and nevers scrolls.

Answer 1

Since I found no solution to this elsewhere, here is mine:
From https://msdn.microsoft.com/en-us/library/windows/apps/mt299120.aspx copy the default Style for the ContentDialog and change the ScrollViewer's Properties from:
<ScrollViewer x:Name="ContentScrollViewer"
HorizontalScrollBarVisibility="Disabled"
VerticalScrollBarVisibility="Disabled"
to
<ScrollViewer x:Name="ContentScrollViewer"
HorizontalScrollBarVisibility="Auto"
VerticalScrollBarVisibility="Auto"
Sounds simple, but I spent too much time debugging the visual tree to figure this out...
Here is the complete Style that you apply to the ContentDialog you want to be scrollable:
<!-- Default style for Windows.UI.Xaml.Controls.ContentDialog -->
<Style TargetType="ContentDialog" x:Key="ScrollableContentDialogStyle">

<Setter Property="MaxHeight" Value="{ThemeResource ContentDialogMaxHeight}" />

Answer 2

Not sure if there has been some related enhancements in the latest SDKs, but at least this works now (very simple way to display long text in a dialog without any new 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();
}

Answer 3

You have to modify the deafult ContentDialog with this content template o créate a new style to use it in your ContentDialog:
<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}"
FlowDirection="{TemplateBinding FlowDirection}"
BorderThickness="{ThemeResource ContentDialogBorderWidth}"
BorderBrush="{ThemeResource SystemControlForegroundAccentBrush}"
MaxWidth="{TemplateBinding MaxWidth}"
MaxHeight="{TemplateBinding MaxHeight}"
MinWidth="{TemplateBinding MinWidth}"
MinHeight="{TemplateBinding MinHeight}">
<Grid x:Name="DialogSpace"
VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<!-- Modify to 'Height="*"' intead of 'Height="Auto"'-->
<RowDefinition Height="*" />
<!-- Modify to 'Height="Auto"' intead of 'Height="*"'-->
<RowDefinition Height="Auto" />
<!-- Delete' RowDefinition -->
<!--<RowDefinition Height="Auto" />-->
</Grid.RowDefinitions>
<ScrollViewer x:Name="ContentScrollViewer"
HorizontalScrollBarVisibility="Disabled"
VerticalScrollBarVisibility="Disabled"
ZoomMode="Disabled"
Margin="{ThemeResource ContentDialogContentScrollViewerMargin}"
IsTabStop="False">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<!-- Delete 'Height="Auto"' of RowDefinition.-->
<RowDefinition />
</Grid.RowDefinitions>
<ContentControl x:Name="Title"
Margin="{ThemeResource ContentDialogTitleMargin}"
Content="{TemplateBinding Title}"
ContentTemplate="{TemplateBinding TitleTemplate}"
FontSize="20"
FontFamily="Segoe UI"
FontWeight="Normal"
Foreground="{TemplateBinding Foreground}"
HorizontalAlignment="Left"
VerticalAlignment="Top"
IsTabStop="False"
MaxHeight="{ThemeResource ContentDialogTitleMaxHeight}">
<ContentControl.Template>
<ControlTemplate TargetType="ContentControl">
<ContentPresenter Content="{TemplateBinding Content}"
MaxLines="2"
TextWrapping="Wrap"
ContentTemplate="{TemplateBinding ContentTemplate}"
Margin="{TemplateBinding Padding}"
ContentTransitions="{TemplateBinding ContentTransitions}"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
</ControlTemplate>
</ContentControl.Template>
</ContentControl>
<ContentPresenter x:Name="Content"
ContentTemplate="{TemplateBinding ContentTemplate}"
Content="{TemplateBinding Content}"
FontSize="{ThemeResource ControlContentThemeFontSize}"
FontFamily="{ThemeResource ContentControlThemeFontFamily}"
Margin="{ThemeResource ContentDialogContentMargin}"
Foreground="{TemplateBinding Foreground}"
Grid.Row="1"
TextWrapping="Wrap" />
</Grid>
</ScrollViewer>
<Grid x:Name="CommandSpace"
Grid.Row="1"
HorizontalAlignment="Stretch"
VerticalAlignment="Bottom">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Border x:Name="Button1Host"
Margin="{ThemeResource ContentDialogButton1HostMargin}"
MinWidth="{ThemeResource ContentDialogButtonMinWidth}"
MaxWidth="{ThemeResource ContentDialogButtonMaxWidth}"
Height="{ThemeResource ContentDialogButtonHeight}"
HorizontalAlignment="Stretch" />
<Border x:Name="Button2Host"
Margin="{ThemeResource ContentDialogButton2HostMargin}"
MinWidth="{ThemeResource ContentDialogButtonMinWidth}"
MaxWidth="{ThemeResource ContentDialogButtonMaxWidth}"
Height="{ThemeResource ContentDialogButtonHeight}"
Grid.Column="1"
HorizontalAlignment="Stretch" />
</Grid>
</Grid>
</Border>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
Hope this help you.

For WinUI 3 (Windows.App.SDK):
The solution is similar but a bit different from #Markus Hütter 's solution.
First, note an easy way to get to the default template for copying and pasting, as #Markus Hütter suggested, is to add Style="{StaticResource DefaultContentDialogStyle}" to your content dialog, Right Click, and select Go To Definition. You can keep the style setting in your content dialog and later replace the style name with the new style name (discussed below).
In my application (and I assume, by default, in all WinUI 3 apps), the style exists in generic.xaml.
Copy the entire style into your App.xaml ResourceDictionary and change the ScrollViewer Disabled settings in the style to Auto, like this:
<ScrollViewer x:Name="ContentScrollViewer" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" ZoomMode="Disabled" IsTabStop="False">
Also, give your new custom style a unique name, such as:
<Style x:Key="MyCustomScrollableContentDialogStyle" TargetType="ContentDialog"> ...
Note, as mentioned, your ContentDialog will need to reference the new style name with Style="{StaticResource MyCustomScrollableContentDialogStyle}"
It's a bit long, but here is my final style:
<!-- 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}" />
