我在windows phone编码方面很新颖,我有我认为是新手问题:),我的网页浏览器不显示。我首先想到这是因为我曾经说过它在我班的构造函数中导航,但改变它并没有解决任何问题。无法让网页浏览器显示在我的手机页面

任何人都可以向我解释什么是错的?

这背后是我的代码:

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:

<phone:PhoneApplicationPage 
    x:Class="LaBanquePostale.MainPage" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

     </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>

您的WebBrowser和TextBlock位于同一网格行中。 TextBlock可能隐藏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,然后查看是否有效。

最终,你的电网应该有两个RowDefinitions,并且是这个样子:

<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>

好,我还是不了解UI项目在WP7中的工作方式。但我会更近一点! Thx guys –

你会发现他们中的很多人不像你期望的那样行事。 – Robaticus

这似乎是因为你设置VerticalAlignment = “顶” 反对WebBrowser控件,移除该属性设置,在我的示例项目中呈现WebBrowser控件。
