Silverlight 3 商业应用程序:如何从 Mainpage 传递查询字符串到 About 页面?
原标题:Silverlight 3 Business application : How to pass query string from Mainpage to About Page?

主页面由列表框、框架和少数超链接组成。单击超链接,相应的页面将加载到框架中。

我该如何通过查询字符串在Silverlight 3中将列表框上的选定项目值传递到正在加载的页面(例如:关于页面)?

任何提示将不胜感激。

最佳回答

根据MSDN页面,您可以使用以下格式指定查询字符串

<uriMapper:UriMapping Uri="/Products/{type}" 
  MappedUri="/Views/ProductDetail.xaml?producttype={type}">
</uriMapper:UriMapping>

我不知道如何通过XAML将类型链接到值,但导航到该页面时,您可以添加一个OnClick事件而不是一个navigateuri。 在OnClick事件中,您将指定类似于以下内容的内容:

private void Link2_Click(object sender, RoutedEventArgs e)
{
    Uri x = new Uri(String.Format(/Products/{0},yourcombo.SelectedItem), UriKind.Relative);

    //ContentFrame is the Navigation Frame
    ContentFrame.Navigate(x);
}

这将导航到ProductDetail.xaml页面。从这里,您可以通过使用string type = this.NavigationContext.QueryString["producttype"];来获取producttype值。

时间 Heuer还拥有一个很好的web 关于导航解决办法。
