Windows Phone 7的ListPicker控件未打开完整选择窗口

Question

以下是空闲时的样子：

在这里，当我点击它时，它应该弹出全屏选择模式（根据我读过的内容）：

如您所见，它似乎没有打开全屏选择模式。

这是我的XAML：

关于我可能做错的任何想法？

Answer 1

您已在ListPicker控件上设置ItemCountThreshold="0"，以便立即进入全屏选择模式。

Answer 2

您还可以在listpicker上设置ExpansionMode="FullScreenOnly"来解决此问题。

Answer 3

控件将包含在Grid.Row中，并将遵守其大小限制。话虽如此，它不会越过第二排的边界。您需要将其放在另一个具有较大高度的Grid.Row内或在弹出窗口中打开它。
