Get data from clicked item in ListBox

问题:

I am new to Windows Phone,

I have one listbox with textblocks in it, I want to fetch all data from selected item in listbox.

Here is my code snippet:

.xaml file

 <ListBox HorizontalAlignment="Left" Name="listbox1" ItemsSource="{Binding}" Margin="9,10,0,0" SelectionChanged="listBox1_SelectionChanged">
              <ListBox.ItemTemplate>
                    <DataTemplate>
                            <StackPanel Margin="0,0,0,5">
                                 <Image HorizontalAlignment="Left" Height="100" Margin="0,15,0,0" VerticalAlignment="Top""/>
                                 <TextBlock Text="{Binding AttractionName}" Foreground="Yellow" Margin="120,-110,0,0""/>
                                 <TextBlock Text="Price:" Foreground="White" TextWrapping="Wrap" FontSize="30""/>
                                 <TextBlock Text="£" Foreground="Green" TextWrapping="Wrap" FontSize="40" Margin="200,-50,12,0""/>
                                 <TextBlock Text="{Binding price}" Foreground="Green" FontSize="40""/>
                                 <Line X1="0" X2="420" Y1="10" Y2="10" Stroke="White" VerticalAlignment="Bottom"/>
                        </StackPanel>
                    </DataTemplate>
              </ListBox.ItemTemplate>
</ListBox>

.cs file

    void listBox1_SelectionChanged(object sender, SelectionChangedEventArgs args)
    {
        Debug.WriteLine(" You selected " +listbox1.SelectedItem.ToString());
    }

My console shows output this way: You selected Appname.Pagename.methodname

Class which is bound to ListBox

    public class Attractions { 
[JsonProperty("AttractionName")]
 public string AttractionName { get; set; }
[JsonProperty("IphoneImage")] 
public string IphoneImage { get; set; } 
[JsonProperty("price")] public string price { get; set; } 
}

回答1:

There are few ways to do it:

private void listBox1_SelectionChanged(object sender, SelectionChangedEventArgs args)
{
    if (listBox1.SelectedIndex == -1) return;

    Attractions first = listbox1.SelectedItem as Attractions ;
    Attractions second = (Attractions)listBox1.Items[listBox1.SelectedIndex];
    Attractions third = (sender as ListBox).SelectedItem as Attractions;
    Attractions fourth = args.AddedItems[0] as Attractions;

    Debug.WriteLine(" You selected " + first.AttractionName);
}

With SelectedItem (Index) you get an item that is Type of your ItemsSource Collection. Once you get the item you can do what you want with it.

Inside SelectionChange Event put the following code

Attractions  lbi = (sender as ListBox).SelectedItem as Attractions;

you can access the properties of the class using

lbi.price
