注意:我已经在应用程序级别设置了此资源字典，并且将Calendarstyle属性全局绑定到所有datepicker.
Note: I've got this resource dictionary set at an application level and I'm globally binding the calendarstyle properties to all datepickers.
这在应用程序级资源字典中:
This is in an app level resource dictionary:
<Style TargetType="{x:Type DatePicker}">
<Setter
Property="CalendarStyle"
Value="{StaticResource CalendarStyle1}" />
</Style>
这是引用资源字典的地方(如果我做错了，我是xaml的新手
And this is where the resource dictionaries are referenced (In case I did it wrong, I'm new to xaml
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary
Source="ResourceDictionary/CustomCalendar.xaml" />
<ResourceDictionary
Source="ResourceDictionary/GlobalStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
推荐答案
您的问题在于您的样式TargetType.如果您发现自己的日历样式定义为:
Your problem is with your style TargetTypes. If you notice you have the style for your calendar defined as:
<Style x:Key="CalendarStyle1" TargetType="{x:Type Calendar}">
并将CalendarItem的样式定义为:
And the style for your CalendarItem defined as:
<Style x:Key="CalenderStyleNew" TargetType="primitives:CalendarItem">
问题是Calendar类型来自标准System.Windows.Controls包，而CalendarItem来自命名空间Microsoft.Windows.Controls(这是您已定义为 primitives 的wpftoolkit命名空间).因此，要解决此问题，您必须使用自己样式中的所有System.Windows.Controls或使用所有Microsoft.Windows.Controls命名空间.
The problem is that the Calendar type is from the standard System.Windows.Controls package but the CalendarItem is from the namespace Microsoft.Windows.Controls (that's the wpftoolkit namespace you have defined as primitives). So to fix this you have to either use ALL System.Windows.Controls in your styles or use ALL Microsoft.Windows.Controls namespaces.
我已解决您使用所有Microsoft.Windows.Controls的问题:
I fixed your issue to use all Microsoft.Windows.Controls:
<Style x:Key="CalendarStyle1" TargetType="{x:Type Controls:Calendar}">
全局样式必须更改为:
<Style TargetType="{x:Type Controls:DatePicker}">
<Setter
Property="CalendarStyle"
Value="{StaticResource CalendarStyle1}" />
</Style>
要实例化DatePicker，必须使用正确的DatePicker:
And to instantiate a DatePicker you must use the correct one:
<Controls:DatePicker />
不
<DatePicker />
如果不从WpfToolkit命名空间引用它，它将没有您的自定义样式.
If you don't reference it from the WpfToolkit namespace it won't have your custom styles.
