Wie stelle ich die Seitennavigation von Listbox auf eine andere Seite ein?
Ich verwende die unten angegebene XAML-Datei. Ich möchte in der Listbox zu einer anderen Seite navigieren.
<ListBox x:Name="NotchsList11" Grid.ColumnSpan="2"

<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0,0,0,0" Grid.ColumnSpan="3" x:Name="ControlsPanel"
Grid.Column="0"
Height="215"
VerticalAlignment="Top">
<StackPanel Background="#eb2427" Orientation="Horizontal">
<TextBlock Grid.Row="1" FontFamily="Calibri" FontSize="34" FontWeight="Bold" FontStyle="Normal" Margin="10,0,0,0"
Text="{Binding name}"
/>
</StackPanel>
<ScrollViewer ScrollViewer.HorizontalScrollBarVisibility="Visible" ScrollViewer.VerticalScrollBarVisibility="Disabled">
<StackPanel>
<StackPanel VerticalAlignment="Top" Width="Auto">
<ListBox ItemsSource="{Binding Images}" SelectionChanged="NotchsList11_SelectionChanged" Width="Auto" ScrollViewer.VerticalScrollBarVisibility="Disabled">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" VerticalAlignment="Top">

Mein MainPage.xaml.cs-Code
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));
}
}
Meine DetailPage.xaml.cs
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
base.OnNavigatedTo(e);
string parameter = this.NavigationContext.QueryString["parameter"];
}
Wenn ich auf ein Bild klicke, navigieren der zugehörige Titel und der vollständige Inhalt zur Detailseite, aber der vollständige Inhalt möchte die Webansicht auf der Detailseite anzeigen. Also habe ich diesen Code ausprobiert, aber selectedItemData bekommt einen Nullwert. Ich kann nicht zu einer anderen Seite navigieren. Kann mir jemand bei der Lösung dieses Problems helfen?
