我下载了一个WPFToolkit来源，因为我想重写的DatePicker的默认通用模板。例如，我想重写这个文本框：
I downloaded a WPFToolkit source, because I wanted to override the default generic template of a DatePicker. For example, I wanted to override this TextBox:
<primitives:DatePickerTextBox x:Name="PART_TextBox"
Grid.Row="0" Grid.Column="0"
Foreground="{TemplateBinding Foreground}"
HorizontalContentAlignment="Stretch"
VerticalContentAlignment="Stretch" />
这意味着，在我的项目写的：
That means that writing this in my project :
<Style TargetType="{x:Type toolkit:DatePickerTextBox}">
<Setter Property="Text" Value="Bitte wählen" />
<Setter Property="MinHeight" Value="20" />
完美的作品。
但是，如果我想改变 VerticalContentAlignment =拉伸到 VerticalContentAlignment =中心什么？默认样式始终会覆盖它。
感谢您的答复！
works perfectly.
But what if I want to change VerticalContentAlignment="Stretch" to VerticalContentAlignment="Center" ?? The default style always overrides it.
Thanks for response!
推荐答案
好吧，我下载了这些控件的来源，直接把这个风格从微软并应用它在我的DatePicker。它的工作！
Ok I downloaded a Source of those controls, took this Style directly from Microsoft and applied it on my DatePicker. It worked!
特别期待这个：
这是我风格我内心的文本框。
Look especially at this:
This is where i style my inner TextBox.
