Question

我是Windows手机编码的新手，我认为这是一个新手问题:)，我的网页浏览器没有显示。我首先想到的是因为我曾经说过要在我班级的构造函数中导航，但改变它并没有解决任何问题。

有人可以向我解释有什么问题吗？

这是我背后的代码：

    public partial class MainPage : PhoneApplicationPage
    {
        string site = "http://google.com/";

        // Constructor
        public MainPage()
        {
            InitializeComponent();

            this.Loaded += new RoutedEventHandler(MainPage_Loaded);

        }


        private void MainPage_Loaded(object sender, RoutedEventArgs e)
        {
            wB.Navigate(new Uri(site, UriKind.Absolute));
            wB.Navigating += new EventHandler<NavigatingEventArgs>(wB_Navigating);
        }

        void wB_Navigating(object sender, NavigatingEventArgs e)
        {
            System.Diagnostics.Debug.WriteLine(e.Uri);
            if (e.Uri.ToString() != (site))
            {
                System.Diagnostics.Debug.WriteLine("lalala");
               // NavigationService.Navigate(new Uri("/Panorama.xaml", UriKind.Relative));
            }
        }
    }
}

这是我的Xaml：

    x:Class="LaBanquePostale.MainPage"

            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <!--TitlePanel contains the name of the application and page title-->
        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
            <TextBlock x:Name="ApplicationTitle" Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}"/>
            <TextBlock x:Name="PageTitle" Text="page name" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
        </StackPanel>

        <!--ContentPanel - place additional content here-->
        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <phone:WebBrowser Name="wB"  VerticalAlignment="Top" d:LayoutOverrides="Width"/>
            <TextBlock HorizontalAlignment="Left" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top"/></Grid>
    </Grid>

</phone:PhoneApplicationPage>

Answer 1

您的WebBrowser和TextBlock位于同一网格行中。 TextBlock可能隐藏了WebBrowser，并且WebBrowser的高度为0，因为它的verticalAlignment设置为Top。

尝试删除TextBlock并将VerticalAlignment设置为Stretch，看看是否有效。

最终，你的网格应该有两个RowDefinitions，看起来像这样：

    <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <Grid.RowDefinitions>
             <RowDefinition Height="*" />
             <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <phone:WebBrowser Name="wB"  VerticalAlignment="Stretch" Grid.Row="0" d:LayoutOverrides="Width"/>
        <TextBlock HorizontalAlignment="Left" Grid.Row="1" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top"/></Grid>
    </Grid>

Answer 2

这似乎是因为您正在针对WebBrowser控件设置VerticalAlignment =“Top”，删除此属性设置，在我的示例项目中显示WebBrowser控件。

无法在我的手机页面上显示网页浏览器
