我正在尝试在标题栏中添加一个按钮.我的XAML如下所示:

<Page
    x:Class="FullScreen.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:FullScreen"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>

        <Grid x:Name="TitleBar">
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto"/>
                    <ColumnDefinition Width="Auto"/>
                </Grid.ColumnDefinitions>
                <TextBlock Grid.Column="0" Text="Application Name" VerticalAlignment="Center"/>
                <Button Grid.Column="1" Content="Test" Click="Button_Click"/>
            </Grid>
        </Grid>

        <Grid Grid.Row="1">
            <TextBlock>Content</TextBlock>
        </Grid>
    </Grid>
</Page>

.cs页面有以下代码:

using System;
using Windows.ApplicationModel.Core;
using Windows.UI.Popups;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;

namespace FullScreen
{
    public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            InitializeComponent();

            CoreApplication.GetCurrentView().TitleBar.ExtendViewIntoTitleBar = true;
            Window.Current.SetTitleBar(TitleBar);
        }
