如何使用这些标签的用户控件

我已经为wp7创建了一个web浏览器应用程序。我在应用程序栏菜单项中添加了6个标签。但现在我想分别在用户控制页面中的这6个选项卡，如果我点击选项卡2或任何选项卡上，它应该现在工作。如何使用这些标签的用户控件

MainPage.xaml中

<Grid x:Name="LayoutRoot"> 
<Grid.RowDefinitions> 
<RowDefinition Height="Auto" /> 
<RowDefinition Height="*" /> 
</Grid.RowDefinitions> 
<TextBox x:Name="UrlTextBox" 
    KeyDown="UrlTextBox_KeyDown" /> 
<Grid x:Name="BrowserHost" 
    Grid.Row="1" /> 
</Grid> 

<phone:PhoneApplicationPage.ApplicationBar> 
<shell:ApplicationBar> 
<shell:ApplicationBar.MenuItems> 
    <shell:ApplicationBarMenuItem Text="1" 
            Click="TabMenuItem_Click" /> 
    <shell:ApplicationBarMenuItem Text="2" 
            Click="TabMenuItem_Click" /> 
    <shell:ApplicationBarMenuItem Text="3" 
            Click="TabMenuItem_Click" /> 
    <shell:ApplicationBarMenuItem Text="4" 
            Click="TabMenuItem_Click" /> 
</shell:ApplicationBar.MenuItems> 
</shell:ApplicationBar> 
</phone:PhoneApplicationPage.ApplicationBar>

MainPage.xaml.cs中

public partial class MainPage : PhoneApplicationPage 
{ 
private const int NumTabs = 4; 

private int currentIndex; 
private string[] urls = new string[NumTabs]; 
private WebBrowser[] browsers = new WebBrowser[NumTabs]; 

public MainPage() 
{ 
InitializeComponent(); 
ShowTab(0); 
} 

private void ShowTab(int index) 
{ 
this.currentIndex = index; 
UrlTextBox.Text = this.urls[this.currentIndex] ?? ""; 
if (this.browsers[this.currentIndex] == null) 
{ 
    WebBrowser browser = new WebBrowser(); 
    this.browsers[this.currentIndex] = browser; 
    BrowserHost.Children.Add(browser); 
} 
for (int i = 0; i < NumTabs; i++) 
{ 
    if (this.browsers[i] != null) 
    { 
     this.browsers[i].Visibility = i == this.currentIndex ? Visibility.Visible : Visibility.Collapsed; 
    } 
} 
} 

private void UrlTextBox_KeyDown(object sender, KeyEventArgs e) 
{ 
if (e.Key == Key.Enter) 
{ 
    Uri url; 
    if (Uri.TryCreate(UrlTextBox.Text, UriKind.Absolute, out url)) 
    { 
     this.urls[this.currentIndex] = UrlTextBox.Text; 
     this.browsers[this.currentIndex].Navigate(url); 
    } 
    else 
     MessageBox.Show("Invalid url"); 
} 
} 

private void TabMenuItem_Click(object sender, EventArgs e) 
{ 
int index = Int32.Parse(((ApplicationBarMenuItem)sender).Text) - 1; 
ShowTab(index); 
} 
}

像下面的浏览器有它。 enter image description here
