我在windows phone編碼方面很新穎,我有我認爲是新手問題:),我的網頁瀏覽器不顯示。我首先想到這是因爲我曾經說過它在我班的構造函數中導航,但改變它並沒有解決任何問題。無法讓網頁瀏覽器顯示在我的手機頁面

任何人都可以向我解釋什麼是錯的?

這背後是我的代碼:

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)); 
      } 
     } 
    } 
} 

這是我的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位於同一網格行中。 TextBlock可能隱藏WebBrowser,並且WebBrowser的高度爲0,因爲它的verticalAlignment設置爲Top。

嘗試刪除TextBlock並將VerticalAlignment設置爲Stretch,然後查看是否有效。

最終,你的電網應該有兩個RowDefinitions,並且是這個樣子:

<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,我還是不瞭解UI項目在WP7中的工作方式。但我會更近一點! Thx guys –

你會發現他們中的很多人不像你期望的那樣行事。 – Robaticus

這似乎是因爲你設置VerticalAlignment = 「頂」 反對WebBrowser控件,移除該屬性設置,在我的示例項目中呈現WebBrowser控件。

老兄你是要命的,這就是你今天幫了我第二次,爲什麼會這樣? –

沒問題,看Robaticus提供的推理 –
