我的 windows phone 7 应用程序中有一些页面，其中包含许多文本框。正如我们所知，windows phone 7 的默认行为是，当我们将焦点放在任何文本框上时，SIP 键盘会出现并向上滑动整个页面，并且在失去焦点时它会恢复到正常状态。我想在我的应用程序中限制这个东西。正如我在谷歌上搜索并找到的解决方案，我们将所有控件放入scrollviewer并textbox设置滚动查看器垂直偏移到该文本框位置的焦点。
现在我很困惑如何告诉滚动查看器我的垂直偏移控件的位置。
假设如果我可以设置那个东西，我需要为我的文本框
on GotFocus和On LostFocus. 有没有其他方法可以通过交互行为和触发器来调用这个东西。

但同样的结果......非常感谢您的帮助。
