ContentDialog Windows 10 移动 XAML - 全屏 - 填充

Question

我在我的项目中放置了一个 ContentDialog 用于 Windows 10 上的登录弹出窗口。 当我在移动设备上运行这个项目时，ContentDialog 没有全屏显示并且在这个元素周围有一个最小的填充。在键盘上是可见的（例如在焦点元素文本框上）在键盘和内容对话框之间存在边距

对于如何在全屏上显示此问题有任何解决方案吗？我将属性“FullSizeDesired”设置为true，问题是否相同？

有人帮助删除这个：- 填充，- 全屏

我的代码是：

<ContentDialog
    x:Class="ExampleApp.SignInContentDialog"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:ExampleApp"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    Title="SIGN IN">

    <Grid x:Name="GridMobile" VerticalAlignment="Center" HorizontalAlignment="Center">

            <Button x:Name="MakeOff" 
            Height="32" BorderThickness="1" 
            HorizontalAlignment="Center"
            Foreground="Red" Background="Black"
            Style="{StaticResource ButtonStyle}"
            Margin="0">

            <HyperlinkButton x:Name="btnRegister"
            Height="32" BorderThickness="1" 
            HorizontalAlignment="Center"
            Foreground="Red" Background="Black"
            Margin="0"
            NavigateUri="www.google.pt"
            Style="{StaticResource HyperLinkButtonStyleMobile}"
            Content="Register">
                <HyperlinkButton.ContentTemplate>
                    <DataTemplate>
                    <TextBlock Text="{Binding}" />
                    </DataTemplate>
                </HyperlinkButton.ContentTemplate>
            </HyperlinkButton>
    </Grid>

我认为页面按钮中的边距/空间是为“PrimaryButton”和“SecondaryButton”保留的 但我需要更多按钮，而且这个边距/空间不适合我。我想删除它。

谢谢。

您看到两者之间的差距的原因不是因为任何特定的Padding 值，而是因为在ContentDialog 的默认样式中，高度和宽度设置为Auto，这意味着您的内容只会考虑到它需要的大小。

因此，让内容拉伸以适合其父级，您只需要通过应用您自己的默认样式 local:SignInContentDialog 并将其放入您的 App.xaml 中来覆盖默认样式。

<Style TargetType="local:SignInContentDialog">
    <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}" />
    <Setter Property="MinHeight" Value="{ThemeResource ContentDialogMinHeight}" />
    <Setter Property="MaxWidth" Value="{ThemeResource ContentDialogMaxWidth}" />
    <Setter Property="MinWidth" Value="{ThemeResource ContentDialogMinWidth}" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="local:SignInContentDialog">
                <Border x:Name="Container">
                    <Grid x:Name="LayoutRoot">                                                     
                        <Grid.RowDefinitions>
                            <RowDefinition Height="Auto" />
                        </Grid.RowDefinitions>

                        <!-- COMMENT OUT THESE FOLLOWING LINES -->

                        <!--<Grid.ColumnDefinitions>
                            <ColumnDefinition Width="Auto" />
