C# WindowPhone FlipView System.ArgumentException

我在WindowsPhone应用程序中使用FlipView时遇到问题。 我有一个带有FlipView的页面，其中包含绑定到ItemsGroup的ItemsSource和绑定到CurrentItem的SelectedItem。FlipView的DataTemplate包括WebView，该WebView具有绑定到CurrentItem的Html的附加属性Html。一切都进行得很顺利，但应用程序会不时出现System.ArgumentException崩溃，我不知道出了什么问题

XAML：

错误：

参数不正确。System.ArgumentException:值不在预期范围内

我已经用自定义模板替换了FlipView的默认模板，在自定义模板中删除了边框的2.5点边距。我不知道怎么做，但它是有效的。可能它与进入边距区域的指针有关，因为从边缘滑动时出错

我观察到了同样的行为。我认为在用户与控件交互时添加项目是flipview中的一个错误。遗憾的是，我们无法重现或定位错误。问题似乎出现在FlipView默认模板的2.5点空白处，但我不知道这与此问题有何关系。我已经删除了它们，问题就消失了。你能详细介绍一下你的解决方案吗？过去几天我遇到了类似的问题。然而，问题似乎不是高度或边距，而是比例。在分配项目时，如果在启动时更改了这些内容，则可能会出现一些问题。
