Question

我在我的应用程序页面上添加了一个ScrollViewer对象，并且我在ScrollViewer对象上添加了许多控件对象，但使用该应用程序的最终用户无法查看所有元素，因为Scroll滚动不够低，而且页面在用户有机会输入任何信息之前，它会一直回到原来的位置。

这是我的XAMLCode：

Answer 1

定义Scrollviewer的高度以使其适合屏幕。

Answer 2

我猜问题就在于这两个陈述。您忘记更改Grid.Row值。请进行更改，然后重试

    <ScrollViewer Grid.Row="1"
     Name="mainScrollViewer"
     Margin="0,175,0,0"
     VerticalScrollBarVisibility="Visible" AllowDrop="False" ManipulationMode="Control">

    <!--ContentPanel - place additional content here-->
    <Grid x:Name="ContentPanel" Margin="12,0,12,0">

如何使ScrollViewer在Windows Phone中正常工作
