C# TabControl继承的CustomControl不'；我什么也没表现出来

首先，我是一个业余爱好者，母语不是英语，所以如果你能对我耐心一点，我将不胜感激；）

在另一个stackoverflow问题之后，我做了一个TabControl，它自己展开（像一个扩展器），只是修改了原始TabControl的模板，所以我可以在选择任何选项卡时改变控件的高度。
这工作得很好，但需要一些逻辑的ViewModel属性。现在我需要再次使用该控件，我认为更好的方法是创建一个CustomControl

我遇到的问题是CustomControl只是没有外观，没有应用任何样式，尽管我在

Generic.xaml

文件中为它指定了样式，并且

Build Action

属性修改了

AsemblyInfo.cs

，并在静态构造函数中使用了

DefaultStyleKeyProperty.OverrideMetadata

。以下是所有其他问题和建议

我认为最好是展示我现在的代码，然后解释我还尝试了什么，我必须说，当我注意到这一点时，我正在编写逻辑，所以它现在不起作用

Generic.xaml：

这是我的最后一次尝试，我的第一次尝试是将

选项卡ExpanderTabControlStyle

样式直接应用于自定义控件，只需更改

TargetType

，然后我尝试了不添加

itemsProperty

，只需在“MainWindow.xaml”中使用相同语法的

选项卡控件

继承的

项目资源

，并将语法更改为：

<Grid>
    <local:TabbedExpander TabStripPlacement="Top">
        <local:TabbedExpander.ItemsS>
            <TabItem Header="prueba1">
                <TextBox Text="prueba1"/>
            </TabItem>
        </local:TabbedExpander.ItemsS>
    </local:TabbedExpander>
</Grid>

以及尝试使用

选项卡控件

继承的

项

唯一有效的方法是将

Generic.xaml

合并为

资源字典

，并将

选项卡ExpanderTabControlStyle

直接应用于自定义控件。。。我想这不是正确的方法。。。正确的？因为我必须将样式应用于我将添加到应用程序中的每个自定义控件

我想要么是我在应用样式，要么是在使用tabitems集合时做错了什么，但现在我没有主意了：（

有什么想法吗？

通常，您会将通用样式添加到窗口（或其他高级控件）资源字典中，如下所示：

<Window.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Themes/Generic.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Window.Resources>

<ResourceDictionary ...>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
        ... other imported resource dictionaries
    </ResourceDictionary.MergedDictionaries>
   ...my application specific stuff...
</ResourceDictionary>

这样所有子控件都将继承它。您尝试过吗

注意，现在您已经创建了一个自定义控件，您需要更改样式的目标类型，并且它将应用于应用程序中控件的所有实例。（尽管看起来您已经想到了这一点）

如果您在其他地方使用此控件，则在其自己的文件中使用此样式可能是值得的，然后其他项目可以将其包含在其自己的generic/windows资源目录中。这就是众所周知的库（如MahHaps.Metro）的工作方式，例如，使用其控件my generic.xaml时可能会是这样的：

<Window.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Themes/Generic.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Window.Resources>

<ResourceDictionary ...>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
        ... other imported resource dictionaries
    </ResourceDictionary.MergedDictionaries>
   ...my application specific stuff...
</ResourceDictionary>

…其他导入的资源字典
…我的应用程序特定的东西。。。

问题是，如果我错了，请纠正我，如果我在将自定义控件添加到应用程序时这样做，我将不得不手动将样式应用于它的所有实例，对吗？对不起，我在未完成注释的情况下按了enter键……我认为使用自定义控件，样式将自动应用于所有实例，因此我应该d方法。不必，不必。如果不指定键，则目标类型的所有子项都将继承样式。哦…我明白了，所以这是通常的方法？但是，很抱歉坚持这样做，如果自定义控件位于其他项目（例如dll）上会发生什么情况，我应该将样式复制/粘贴到应用程序项目中吗？您可能应该将其包含在一个单独的资源字典文件中，该文件可以添加到其他项目中（请参阅我的编辑以回答）。这是否正常？不确定。我见过使用著名的控件/主题库（如MahApps.Metro）来完成此操作。但我不能说这是否正常！
