我下载并安装了 WPF 工具包（它提供了 VS2008 无法及时发布的控件）。
但是，DatePicker 控件看起来不像它的 WinForms 表亲。
替代文字 http://www.angryhacker.com/toys/datepicker.png
首先，下拉按钮不是下拉菜单，而是日历的小图。其次，日历在控件的右侧而不是在其下方打开。如何使控件看起来像普通的日期选择器？还是我应该使用其他东西？

如果有的话，您还可以使用 Expression Blend 提取默认控件模板。只需在新项目中创建 DatePicker 的实例，然后选择它 - 在“对象”菜单中应该有编辑控件样式和模板的选项，包括编辑现有模板副本的选项。
修改模板后，只需将其粘贴到资源字典中并从您的 xaml 中引用它。我这样做是因为我想为 DatePicker、GridView 和 ListBox 控件创建自定义模板。

您可以从 CodePlex 下载源代码并从 generic.xaml 中检索当前的 ControlTemplate。然后，您可以将其复制到您的应用程序资源中并从那里修改控制模板。
与重新定义 .NET 3.5 附带的控件的 ControlTemplates 没有什么不同，它们也是二进制的。我今天才真正做到这一点，很抱歉包含一大堆 XAML，但这是我将“15”按钮重新设置为更“网格”日历外观的方法。您要么必须将其放入 App.Xaml 中，要么将其作为合并字典包含在内。
