我的代码如下所示,我收到以下错误。
码:
<controls:PanoramaItem Header="headlines"> <TextBlock Text="{Binding Tones}" /> <!--Double line list with image placeholder and text wrapping--> <ListBox Margin="0,-12,0" ItemsSource="{Binding Tones}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Margin="0,17"> <!--Replace rectangle with image--> <Image Source="{Binding ImageUrl}" Height="75" Width="100" Margin="12,10,9,0" VerticalAlignment="Top"/> <!--<Rectangle Height="100" Width="100" Fill="#FFE5001b" Margin="12,0"/>--> <StackPanel Width="311"> <TextBlock Text="{Binding Title}" TextWrapping="Wrap" Style="{StaticResource PhoneTextLargeStyle}"/> <!--<TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>--> </StackPanel> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </controls:PanoramaItem>
一个PanoramaItem只能有一个子控件,但是你目前有一个TextBlock和一个ListBox。要解决这个问题,只需添加另一个父控件来保存TextBlock和ListBox(如StackPanel或Grid)。例如:
