从列表框中单击的项目中获取数据

问题描述

我是 Windows Phone 的新手，

I am new to Windows Phone,

我有一个带有文本块的列表框，我想从列表框中的选定项目中获取所有数据.

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

这是我的代码片段:

.xaml 文件

 <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 文件

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

我的控制台以这种方式显示输出:You selected Appname.Pagename.methodname

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

绑定到ListBox的类

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; }
}

推荐答案

有几种方法可以做到:

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);
}

使用 SelectedItem(索引)，您将获得一个属于您的 ItemsSource 集合类型的项目.拿到物品后，您就可以随心所欲地使用它.

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.
