UWP 中的 ContentDialog，糟糕的滚动行为 [英] ContentDialog in UWP, bad scrolling behavior

问题描述

我特意用一个高的 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.那里发生了什么?

<滚动查看器><堆栈面板><按钮>你好</按钮><按钮>你好</按钮><按钮>你好</按钮><按钮>你好</按钮><按钮>你好</按钮><按钮>你好</按钮><按钮>你好</按钮><按钮>你好</按钮><按钮>你好</按钮><按钮>你好</按钮><按钮>你好</按钮><按钮>你好</按钮></StackPanel></ScrollViewer></ContentDialog>

但是，页面内的相同内容会正确显示滚动条.

解决方案

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，

将禁用的 VerticalScrollBarVisibility 值修改为自动" 是不需要的！

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~@20151122

我和你有同样的问题，我在 bing 或 google 中搜索了很多结果.但都无济于事.

不过哈哈，我找到了一个简单的搞定方法.

首先看这个:https://social.msdn.microsoft.com/Forums/windowsapps/en-US/9112c2fe-1d93-48c9-9638-815be8005b86/uwpwindows-10-uap-scrollviewer-in-contentdialog><块引用>

但在我的情况下也无用.然后我换了花药系，搞定了.

在 ScrollViewer 节点中，我修改了 VerticalScrollBarVisibility值禁用到自动和它搞定.

我的英文很差，希望能帮到你.我的开发环境是 win10 版本 10240

完整代码如下:

<ContentControl x:Name="UserInfoDialogContentControl"/><ContentDialog.Template><ControlTemplate TargetType="ContentDialog"><Border x:Name="Container"><Grid x:Name="LayoutRoot"><Grid.RowDefinitions><RowDefinition Height="自动"/></Grid.RowDefinitions><Grid.ColumnDefinitions><ColumnDefinition Width="Auto"/></Grid.ColumnDefinitions><Border x:Name="背景元素"背景="{模板绑定背景}"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><RowDefinition Height="自动"/><RowDefinition Height="*"/><RowDefinition Height="自动"/></Grid.RowDefinitions><ScrollViewer x:Name="ContentScrollViewer"Horizo​​ntalScrollBarVisibility="禁用"VerticalScrollBarVisibility="自动"ZoomMode="禁用"边距="{ThemeResource ContentDialogContentScrollViewerMargin}"IsTabStop="假"><网格><Grid.RowDefinitions><RowDefinition Height="自动"/><!--这里，我删除了 RowDefinition 的 'Height="Auto"'.--><行定义/></Grid.RowDefinitions><ContentControl x:Name="标题"Margin="{ThemeResource ContentDialogTitleMargin}"内容="{模板绑定标题}"ContentTemplate="{TemplateBinding TitleTemplate}"字体大小=20"FontFamily="Segoe UI"FontWeight="正常"Foreground="{TemplateBinding Foreground}"水平对齐=左"垂直对齐=顶部"IsTabStop="假"MaxHeight="{ThemeResource ContentDialogTitleMaxHeight}" ><ContentControl.Template><ControlTemplate TargetType="ContentControl"><内容展示者内容="{模板绑定内容}"MaxLines="2"TextWrapping="Wrap"ContentTemplate="{TemplateBinding ContentTemplate}"边距="{模板绑定填充}"ContentTransitions="{TemplateBinding ContentTransitions}"Horizo​​ntalAlignment="{TemplateBinding Horizo​​ntalContentAlignment}"VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/></控制模板></ContentControl.Template></内容控制><ContentPresenter x:Name="内容"ContentTemplate="{TemplateBinding ContentTemplate}"内容="{模板绑定内容}"FontSize="{ThemeResource ControlContentThemeFontSize}"FontFamily="{ThemeResource ContentControlThemeFontFamily}"边距="{ThemeResource ContentDialogContentMargin}"Foreground="{TemplateBinding Foreground}"Grid.Row="1"TextWrapping="Wrap"/></网格></ScrollViewer><Grid x:Name="CommandSpace" Grid.Row="1" Horizo​​ntalAlignment="Stretch" VerticalAlignment="Bottom"><Grid.ColumnDefinitions><列定义/><列定义/></Grid.ColumnDefinitions><Border x:Name="Button1Host"Margin="{ThemeResource ContentDialogBu​​tton1HostMargin}"MinWidth="{ThemeResource ContentDialogBu​​ttonMinWidth}"MaxWidth="{ThemeResource ContentDialogBu​​ttonMaxWidth}"Height="{ThemeResource ContentDialogBu​​ttonHeight}"Horizo​​ntalAlignment="拉伸"/><Border x:Name="Button2Host"Margin="{ThemeResource ContentDialogBu​​tton2HostMargin}"MinWidth="{ThemeResource ContentDialogBu​​ttonMinWidth}"MaxWidth="{ThemeResource ContentDialogBu​​ttonMaxWidth}"Height="{ThemeResource ContentDialogBu​​ttonHeight}"Grid.Column="1"Horizo​​ntalAlignment="拉伸"/></网格></网格></边框></网格></边框></控制模板></ContentDialog.Template></ContentDialog>

I've created this ContentDialog with a tall StackPanel on purpose, but even though the contents are inside a ScrollViewer, the content appears clipped when it doesn't have enough space. What's going on there?

<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>

However, the same content inside a Page shows the ScrollBars properly.

解决方案
