C# 是否可以在UWP中的弹出窗口中显示网络视图？

我想在a中显示一个简单的代码，我尝试了这段代码，但似乎不起作用

<Popup  x:Name="StandardPopup">
    <Border BorderBrush="{StaticResource ApplicationForegroundThemeBrush}" 
        Background="{StaticResource ApplicationPageBackgroundThemeBrush}"
        BorderThickness="2" Width="200" Height="200">
        <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
            <WebView x:Name="webView1" Source="https://www.bing.com/" HorizontalAlignment="Center"/>
            <Button Content="Close" Click="ClosePopupClicked" HorizontalAlignment="Center"/>
        </StackPanel>
    </Border>
</Popup>

在弹出控件中显示网站的WebView上没有问题。如果您在VisualStudio中检查visual树，则问题只是由于WebView的实际大小为零。您可以为它设置适当的大小，然后您将看到WebView运行良好

<Popup  x:Name="StandardPopup">
        <Border BorderBrush="{StaticResource ApplicationForegroundThemeBrush}"
    Background="{StaticResource ApplicationPageBackgroundThemeBrush}"
    BorderThickness="2" Width="200" Height="200">
            <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
                <WebView x:Name="webView1" Source="https://www.bing.com/" Width="200" Height="200" HorizontalAlignment="Center" NavigationCompleted="WebView1_NavigationCompleted" />
                <Button Content="Close" Click="ClosePopupClicked" HorizontalAlignment="Center" />
            </StackPanel>
        </Border>
    </Popup>
