Question

my problem is exactly similar to this article

但我需要在wp8.1运行时实现。我在滚动时想要textblock（name = txt_latest_update）

这是我的XAML代码

<Grid Name="Root_content" Background="#FFF7FDF7">
    <Grid.RowDefinitions>
        <RowDefinition Height="70"/>          
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>

    <Border Grid.Row="0" Background="Red">
        <Image Source="/Assets/nepaltoday.png" HorizontalAlignment="Left" Margin="10,0,0,0"/>     
    </Border>

    <ScrollViewer Grid.Row="1"   Name="frontpage_scrollview" VerticalScrollBarVisibility="Visible"

有什么建议吗？

Answer 1

嘿，我认为你的问题是，你希望在列表滚动时保持你的文本块固定。所以你必须将你的列表保存在需要修复的不同网格中的不同网格和文本块中。并制作包含列表scrolable = true的网格。
