控制是白色的設置DefaultStyleKey

Question

時，我似乎無法找到具有類似於此的任何地方的一個問題...

所以我有一個從按鈕繼承的自定義控制人。當我不應用默認樣式時，它會加載通用的Button樣式，並且一切都很好，並且很棒。當我應用樣式時，控件呈現爲沒有任何功能的純白色方塊（點擊不起作用等）。我敢肯定這是我的風格，這是搞砸了，但是當我通過XAML中的一個鍵應用風格，它工作正常。

我的代碼...

[TemplateVisualState(Name = "Normal", GroupName = "Common"), 
TemplateVisualState(Name = "Disabled", GroupName = "Common"), 
TemplateVisualState(Name = "Pressed", GroupName = "Common"), 
TemplateVisualState(Name = "MouseOver", GroupName = "Common"), 
TemplateVisualState(Name = "Alert", GroupName = "AlarmStates"), 
TemplateVisualState(Name = "NoAlert", GroupName = "AlarmStates"), 
TemplateVisualState(Name = "Warning", GroupName = "AlarmStates")] 
public class AlarmButtonControl : Button 
{ 
    /// <summary> 
    /// Constructor 
    /// </summary> 
    public AlarmButtonControl() 
    { 
     this.DefaultStyleKey = typeof(AlarmButtonControl); 
    } 
} 

和XAML的風格...

<ControlTemplate x:Key="StatusButton" > 
     <Grid> 
      <VisualStateManager.VisualStateGroups> 
       <VisualStateGroup x:Name="Common"> 
        <VisualStateGroup.Transitions>

您還沒有包括Style只是ControlTemplate。同樣對於默認樣式，您應該只分配樣式的TargetType屬性。像後續的東西應該是在主題\ generic.xaml文件：

<Style TargetType="local:AlarmButtonControl"> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="local:AlarmButtonControl"> 
       <!-- Your template contents here --> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style>
