Question

我的评论部分有评论，每个评论都可以留下回复。它看起来像这样：

<ListBox x:Name="list" ScrollViewer.VerticalScrollBarVisibility="Hidden" ItemsSource="{Binding Comments}">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel>
                <TextBlock x:Name="comment" FontSize="15" Foreground="Black" Text="{Binding Text}" TextWrapping="Wrap" Margin="0,1,0,5" Padding="{Binding Depth, Converter={StaticResource LevelToPaddingConverter}, ConverterParameter=15}"/>
                <Grid Grid.Row="1">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="auto"/>
                     </Grid.ColumnDefinitions>
                     <StackPanel Orientation="Horizontal">
                         <TextBlock x:Name="author" Style="{StaticResource commentInfo}" Text="{Binding UserId, Converter={StaticResource UserIdToUserNameConverter}}" Padding="{Binding Depth, Converter={StaticResource LevelToPaddingConverter}, ConverterParameter=15}"/>
                         <TextBlock Text="," Style="{StaticResource commentInfo}"/>
                         <TextBlock x:Name="timeAgo" Style="{StaticResource commentInfo}" Text="{Binding CreatedAt, Converter={StaticResource TimestampToAgoConverter}}"/>
                     </StackPanel>
 <!-- THIS BUTTON --><HyperlinkButton x:Name="reply" Grid.Column="1" FontSize="10" Foreground="Blue" Content="Reply" HorizontalAlignment="Right" Tapped="reply_Tapped"/>
                     <StackPanel x:Name="replyBox" Visibility="Collapsed" Margin="0,19,0,0">
                         <TextBox PlaceholderText="Write Comment..." FontSize="11" BorderBrush="Gray" BorderThickness="1" Margin="0,0,0,3" Height="50" GotFocus="TextBox_GotFocus" LostFocus="commentBox_LostFocus" TextWrapping="Wrap"/>
                         <Button Content="Post Reply" FontSize="12" Background="CornflowerBlue" BorderThickness="0" Style="{StaticResource ButtonStyle1}" Width="75" Height="25" HorizontalAlignment="Right" Tapped="PostCommentButton_Tapped"/>
                     </StackPanel>
                 </Grid>
             </StackPanel>
         </DataTemplate>
     </ListBox.ItemTemplate>
 </ListBox>

当用户点击该按钮时，可以看到TextBox和Button以进行纪念。但是，如果用户在其他评论上点击回复，则有两个{{1}}可见（每个用于相关评论）。但我希望当用户点击回复到另一条评论时，之前的TextBox会崩溃，因此当时只能看到一个TextBox。我怎么能这样做？

我找到了解决方案。我遍历控制中的所有$('body, html')并找到名称为 replyBox 的那些，然后我将它们折叠。
我是这样做的：

StackPanels

foreach (StackPanel sp in FindVisualChildren<StackPanel>(this)) { if (sp.Name == "replyBox") { sp.Visibility = Visibility.Collapsed; } } //and here showing function for the one I wnat to be visible函数看起来像这样：

FindVisualChildren

我从this answer获得了想法

仅显示用户点击的项目，折叠其他项目
