WPF 中的停靠和定位

我来自WinForms背景，开始学习WPF。 我已经在 Pluralsight 上浏览了一组教程，但在处理大小调整时遇到了一些困难。

调整大小时，我的文本框似乎没有以我想要的方式"锚定"。 我在下面包括 xaml，其中包含有关我正在寻找的行为的注释。 如有任何关于最佳做法的反馈，将不胜感激。 代码对我来说只是"感觉"有点尴尬，但我不确定这是否是因为它对我来说只是新的，或者是否有更简单/更好的方法来做我正在尝试的事情。

若要了解事物的外观，而无需加载下面的 XAML - 下面是调整窗体屏幕截图大小之前和之后的内容。调整大小之前 http://dboasis.com/screenshots/beforeresize.jpg调整大小后 http://dboasis.com/screenshots/afterresize.jpg

我希望在看到我如何在 XAML 中尝试这样做后，提供如何处理调整大小问题以及最佳实践的建议。

另外 - xaml 确实实现了 DevExpress 控件 - 如果有人希望我重做表单而不使用 3rd 方控件，以便他们更轻松地提出建议，我很乐意这样做。
