不工作（使用修改的模板）WPF日期選擇日曆按鈕

我提前道歉，如果這是已經在那裏（我做了一個先進的搜索，但沒有找到這個具體問題。）不工作（使用修改的模板）WPF日期選擇日曆按鈕

我使用一個自定義WPF Datepicker日曆模板（只需更改顏色），但現在我的按鈕不起作用。它會彈出日曆，但從這一點來說沒有任何作用，我錯過了什麼？這裏的代碼如下：

注：我有設置在應用程序級別此資源字典，我約束力的全球性的calendarstyle屬性所有datepickers。

這是一個應用程序級別的資源字典：

<Style TargetType="{x:Type DatePicker}"> 
    <Setter 
     Property="CalendarStyle" 
     Value="{StaticResource CalendarStyle1}" /> 
</Style>

而且這是在資源字典中引用（如果我沒有錯，我是新來的XAML

<Application.Resources> 
    <ResourceDictionary> 
     <ResourceDictionary.MergedDictionaries> 
      <ResourceDictionary 
       Source="ResourceDictionary/CustomCalendar.xaml" /> 
      <ResourceDictionary 
       Source="ResourceDictionary/GlobalStyles.xaml" /> 
     </ResourceDictionary.MergedDictionaries> 
    </ResourceDictionary> 
</Application.Resources>

您的問題與您的風格TargetTypes有關如果您發現您的日曆風格定義爲：

<Style x:Key="CalendarStyle1" TargetType="{x:Type Calendar}">

並確定您CalendarItem的風格：

<Style x:Key="CalenderStyleNew" TargetType="primitives:CalendarItem">

的問題是，日曆類型與標準System.Windows.Controls方案，但CalendarItem是從命名空間Microsoft.Windows.Controls（這是wpftoolkit命名空間你已經定義爲primitives）。所以要解決這個問題，你必須在你的樣式中使用所有的System.Windows.Controls，或者使用所有的Microsoft.Windows.Controls命名空間。

我固定您的問題使用所有Microsoft.Windows.Controls：

<Style x:Key="CalendarStyle1" TargetType="{x:Type Controls:Calendar}">

全球風格必須改爲：

<Style TargetType="{x:Type Controls:DatePicker}"> 
    <Setter 
    Property="CalendarStyle" 
    Value="{StaticResource CalendarStyle1}" /> 
</Style>

並以實例化一個datepicker，您必須使用正確的：

<Controls:DatePicker />

不

<DatePicker />

如果您沒有從WpfToolkit命名空間中引用它，它將不會有您的自定義樣式。

乾杯，埃裏克
