wpf - 在自定义控件中未调用OnApplyTemplate

Question

我有一个使用某些PART控件的自定义控件：

 [TemplatePart(Name = "PART_TitleTextBox", Type = typeof(TextBox))]
    [TemplatePart(Name = "PART_TitleIndexText", Type = typeof(Label))]
    [TemplatePart(Name = "PART_TimeCodeInText", Type = typeof(TextBlock))]
    [TemplatePart(Name = "PART_TimeCodeOutText", Type = typeof(TextBlock))]
    [TemplatePart(Name = "PART_ApprovedImage", Type = typeof(Image))]
    [TemplatePart(Name = "PART_CommentsImage", Type = typeof(Image))]
    [TemplatePart(Name = "PART_BookmarkedImage", Type = typeof(Image))]
    public class TitleBoxNew : Control
    {
        static TitleBoxNew()
        { 
            DefaultStyleKeyProperty.OverrideMetadata(
                typeof(TitleBoxNew),
                new FrameworkPropertyMetadata(typeof(TitleBoxNew)));
        } 

        public TitleBoxNew() { }

        // ... rest of class
    }

此控件将覆盖OnApplyTemplate：

public override void OnApplyTemplate()
{
      base.OnApplyTemplate();

      InitializeEvents();
}

在大多数情况下，效果很好。我已将该控件添加到窗口中的自定义选项卡控件中，并且以某种方式从未为该控件调用OnApplyTemplate！为什么这不能按我预期的那样工作？

对于可能偶然发现本文的其他人，我遇到了同样的问题，我设法通过将以下内容添加到包含我的自定义控件的项目的AssemblyInfo.cs中来解决了这个问题：

[assembly: ThemeInfo(
    ResourceDictionaryLocation.None, //where theme specific resource dictionaries are located
    //(used if a resource is not found in the page, 
    // or application resource dictionaries)
    ResourceDictionaryLocation.SourceAssembly //where the generic resource dictionary is located
    //(used if a resource is not found in the page, 
    // app, or any theme specific resource dictionaries)
)]

我控件的模板位于与控件相同的项目中的Theme / Generic.xaml文件中。
