Couple of options...
几个选项...
You could copy the entire style for the DatePicker control and edit the XAML and use that as the default resource making the TargetType DatePicker which will force it to be used across the application.
您可以复制 DatePicker 控件的整个样式并编辑 XAML 并将其用作创建 TargetType DatePicker 的默认资源，这将强制它在整个应用程序中使用。
You could also edit the style locally and place your own TextBox in the style and hide the DatePickerTextBox and then setup the binding appropriately.
您还可以在本地编辑样式并将您自己的 TextBox 放在样式中并隐藏 DatePickerTextBox，然后适当地设置绑定。

the issue is you are attempting to access date with time. that doesn't work.
问题是您正在尝试随时间访问日期。那行不通。
the date today is represented in "DateTime.Today"
今天的日期用“DateTime.Today”表示

If you need to set the date programmatically (or in the code behind) you could try...
如果您需要以编程方式（或在后面的代码中）设置日期，您可以尝试...
datePicker.Text = DateTime.Now.Date.ToString();
