Мой код MainPage.xaml.cs
void ParseXMLFile(string dataInXmlFile)
{
try
{
//Parsing XML File
XDocument xmlDoc = XDocument.Parse(dataInXmlFile);
var query = from l in xmlDoc.Descendants("Category")
select new Notch
{
name = (string)l.Attribute("name").Value,
Titles = l.Element("Articles").Elements("article")
.Select(s => s.Attribute("title").Value)
.ToList(),
Images = l.Element("Articles").Elements("article")
.Elements("thumb_image").Elements("image")
.Select(x => x.Attribute("url").Value).ToList(),
};
foreach (var result in query)
{
Console.WriteLine(result.name);
foreach (var detail in result.Titles.Zip(result.Images, (st, si) => string.Format("{0} {1}", st, si)))
{
Console.WriteLine(detail);
}
}
NotchsList11.ItemsSource= query;
}
catch(Exception e)
{
MessageBox.Show("Binding Failed");
}
}
private void NotchsList11_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
Notch selectedItemData = (sender as ListBox).SelectedValue as Notch;
if(selectedItemData != null)
{
NavigationService.Navigate(new Uri(string.Format("/Test.xaml?parameter",selectedItemData.articleid), UriKind.Relative));
}
}
Мой DetailPage.xaml.cs
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
base.OnNavigatedTo(e);
string parameter = this.NavigationContext.QueryString["parameter"];
}
Если я щелкну любое изображение, связанный заголовок и полный контент перейдут на страницу сведений, но полный контент захочет показать веб-просмотр на странице сведений. поэтому я попробовал этот код, но selectedItemData получает нулевое значение. Я не могу перейти на другую страницу. Так кто-нибудь может помочь мне решить эту проблему?
