我有这个枢轴控件，它将与一些数据绑定：

[编辑] 这是我的完整xaml，我试图放置Grid.Row定义但仍然无法正常工作。

    </phone:Pivot>


</Grid>

但是滚动浏览器不起作用，我不知道为什么会发生这种情况。

我尝试了这个Thread的建议，但它没有用。有人可以帮帮我吗？

感谢。

Answer 1

尝试在Grid ContentPanel下添加以下代码：

<Grid.RowDefinitions>
    <RowDefinition Height="*"/>
</Grid.RowDefinitions>

实际上，您的代码在我测试时运行良好。

如果您需要进一步的帮助，可能需要粘贴整个xaml。

Answer 2

我在PivotItem中有一个与ScrollViewer类似的问题。问题是ScrollViewer中的内容（网格）与PivotItem的高度相同，因此ScrollViewer实际上没有任何内容可以滚动。我通过使PivotItem高度小于ScrollViewer内容的高度来解决问题。

Answer 3

问题是由于使用了多个ScrollViewer;当LongListSelector中的项超过控件的大小时，它具有默认的滚动机制，因此我们不需要在LongListSelector上显式地放置ScrollViewer。

在您的情况下，将有两个滚动查看器，一个来自LongListSelector，另一个是您明确放置的。所以滚动没有发生。

因此，只需从所有数据透视表项中删除ScrollViewer，并将Grid.Row属性设置为LongListSelector。

枢轴项目不垂直滚动
