Question

我一直在尝试为Windows Phone 8.1制作应用程序我决定使用集线器模板。我设计了我的应用程序，现在当我尝试运行它时，每次都会抛出一个exeption。这让我非常困惑，因为我使用vs自己的控件进行了所有设计并且没有编写任何我自己的xaml。但我得到一个windows.UI.Xaml.UnhandledException任何关于这个的帮助真的很棒这是我为Windows手机制作的第一批应用之一，所以我对这个主题相当新。如果有任何用途，这是xaml。

再次感谢您的帮助。

您正在替换HubSection的模板。

通过设置

来设置HubSection的ControlTemplate

<HubSection Template="{...}">...</HubSection>

此模板需要具有名称＆＃34; WrappingTransform＆＃34;的CompositeTransform。在它的根元素上，Hub Control可以正常工作。

您真的只想设置HubSections子DataTemplate。

<HubSection Header="Add Hours">
    <DataTemplate>...</DataTemplate>
</HubSection>

HubSection的内容是DataTemplate可能有点令人困惑，但请记住，内容属性（也就是HubSection内部的内容）而不是模板属性（也就是HubSection本身的外观，它想要修改的边框，间距等。
