这是我要提取享受ID的图像
我想从数据有界的选定项目中提取享受ID,但由于invalidCastException,我尝试了web中可用的所有方法仍然无法提取它。
private void listBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
SuperData data = (sender as ListBox).SelectedItem as SuperData;
ListBoxItem selected = this.listBox1.ItemContainerGenerator.ContainerFromItem(data) as ListBoxItem;
}
我试过这个和 e.AddedItem[0] 但仍然无法得到它。
<Grid>
<ListBox HorizontalAlignment="Stretch" Margin="0,0,0,0" Name="listBox1" VerticalAlignment="Stretch" SelectionChanged="listBox1_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Height="132">
<Image Source="{Binding image}" Height="73" Width="73" VerticalAlignment="Top" Margin="0,10,8,0"/>
<StackPanel Width="370">
<TextBlock Text="{Binding title}" Foreground="#FFC8AB14" FontSize="28" />
<!--TextBlock Text="{Binding Message}" TextWrapping="Wrap" FontSize="24" /-->
<TextBlock Text="{Binding description}" TextWrapping="Wrap" FontSize="24" />
<TextBlock Text="Test" TextWrapping="Wrap" FontSize="24" />
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
这是我绑定数据的 UI 部分。WCF 的返回是List<REData>
数据类型,我只是用 . 绑定到列表框listBox1.ItemsSource = e.Result
。
public int category { get; set; }
public int categoryField { get; set; }
public string description { get; set; }
public string descriptionField { get; set; }
public int enjoymentID { get; set; }
public int enjoymentIDField { get; set; }
public string image { get; set; }
public string imageField { get; set; }
public object PropertyChanged { get; set; } << i don't know what is this
public string title { get; set; }
public string titleField { get; set; }
这也是 e.AddedItem[0] 中的内容:
