C# WPF自定义控件不可见-找不到主题？

c# wpf

C# WPF自定义控件不可见-找不到主题？,c#,wpf,C#,Wpf,我正在尝试构建一个WPF自定义控件库，以便从不同的WPF软件项目中使用。我正在使用VisualStudio2019。我使用WPF自定义控件库（.NET Framework）模板创建了一个新项目，其中定义了文本框的子类： CustomControl1.cs: using System.Windows; using System.Windows.Controls; namespace CCL1 { public class CustomControl1 : TextBox {

普通文本框只是用来比较的。我可以看到我的CustomControl1类，它是设计模式下TextBox的一个子类，但当我构建并启动应用程序时，它并不在那里。我的搜索告诉我这是因为找不到自定义控件的主题，特别是以下问题：告诉我，如果我将第二个答案中详细说明的行添加到AssemblyInfo中，那么它应该可以工作-但是这一行已经包含在AssemblyInfo中（从一开始就是这样，它是项目模板的一部分），并且没有任何区别。我可以通过注释自定义控件的静态构造函数来显示它，但这似乎是一个残酷的攻击，我不想被限制为控件的默认主题，我希望它能按预期工作

最奇怪的是，几个小时前这确实奏效，但后来突然变成了我刚才描述的行为。我不记得有什么特别的改变来实现这一点

很抱歉重新发布了一个以前被问到的问题，但我只是不知道我在做什么，与已经给出的答案不同

编辑：重新构建时，自定义控件现在在设计模式下甚至不可见…

使用您提供的示例代码，控件模板没有任何显示。您正在设置

Text=“Hello”

，但是您没有

ContentPresenter

，也没有绑定到

Text

属性

我建议提取文本框的控件模板，并将其用作自定义控件的起点。

尝试在

控件模板的边框中添加一些内容。您当前的模板似乎为空。这有助于感谢您。我在这里也得到了一些很好的信息：以防有人还在寻找。
