How to make a dynamic menu in Windows Phone 7

Question

Windows phone

In general, I decided to try myself in this business, to write a client for my site for the purpose of self-education. No monetization is foreseen

:) for example, I get a list of objects from the site. Then I want that when tapping on an object, a page with a description of the object opens.

So far I've done it like this:

XAML:

                    <ListBox  HorizontalAlignment="Left" Margin="9,0,0,0" Name="listBox1" VerticalAlignment="Top" SelectionChanged="OnChange" ItemsSource="{Binding}" SelectionMode="Single" >
                        <ListBox.ItemTemplate>
                            <DataTemplate>
                                <StackPanel Orientation="Horizontal" Margin="4">
                                    <Image Source="{Binding Path=Logo}" Width="82" Height="62" Stretch="Fill" />
                                    <StackPanel Margin="4,0,0,0">
                                        <TextBlock Text="{Binding Path=Name}" TextWrapping="Wrap" TextTrimming="WordEllipsis" />
                                        <StackPanel Orientation="Horizontal">
                                            <TextBlock Text="Инвестиции от " TextWrapping="Wrap" />
                                            <TextBlock Text="{Binding Path=Invest}" TextWrapping="Wrap" />
                                            <TextBlock Text=" руб." TextWrapping="Wrap" />
                                        </StackPanel>
                                    </StackPanel>
                                </StackPanel>
                            </DataTemplate>
                        </ListBox.ItemTemplate>

WITH#:

                    var searchResults = from result in resultXml.Descendants("fr")
                                        select new FranchiseOnMain
                                        {
                                            // Get the Title, Description and Url values.
                                            Logo = result.Element("logo").Value,
                                            Name = result.Element("name").Value,
                                            Id = result.Element("id").Value,
                                            Invest = result.Element("invest").Value
                                        };
                    listBox1.DataContext = searchResults;

Those. there is a listbox in which I load the data received from the server in xml format.

Now I need to tap on the listbox element to open another page with an extended description of this object.

I did it like this:

        private void OnChange(object sender, SelectionChangedEventArgs e)
        {
            if (listBox1.SelectedItem != null)
            {
                TextBlock textblock1 = new TextBlock();
                FranchiseOnMain fr = (FranchiseOnMain)listBox1.SelectedItem;
                string uri = "/FranchisePage.xaml?id=" + fr.Id + "&name=" + fr.Name;
                NavigationService.Navigate(new Uri(uri, UriKind.RelativeOrAbsolute));
                listBox1.SelectedItem = null;
            }
        }

Those. after selecting an object, I open another page with a parameter using the navigation service, and reset the selection so that when I return back to the main page, nothing is selected in the listbox.

If the selection is not reset, then the problem arises that when I return to the list of objects, I cannot get to the same one again because it is already selected in the listbox and SelectionChanged does not work.

But I don't like this solution, I want to do it right. How to do it right? Do I need to use not a listbox, but some other control? Are there other controls that can automatically load a collection of objects or will it be necessary to do this manually? In principle, doing it manually is not a problem if you tell me which control to set to navigate between pages (with a normal click animation).

Answer 1

Alternatively, you can use OnTap on the ListBox, then you don't have to deselect the element (besides, it's generally bad from a UX point of view).
