TabControl的繼承CustomControl不顯示任何

首先，我是一個業餘和非英語母語的人，所以我會很感激，如果你跟我有一點耐心;）TabControl的繼承CustomControl不顯示任何

繼另一個問題計算器，我做了一個TabControl，它擴展自己（像擴展器），只是修改原始TabControl的模板，所以我可以在選擇任何選項卡時更改控件的高度。
這工作完美，但需要邏輯的一些ViewModel屬性。現在我需要再次使用該控件，並且我認爲更好的方法是創建一個CustomControl。

我遇到的問題是，CustomControl只是無外觀，沒有風格適用於它，雖然我已經在Generic.xaml文件中指定爲它的風格，和Build Action財產Page，修改了AsemblyInfo.cs，以及所使用的DefaultStyleKeyProperty.OverrideMetadata在靜態構造函數中。所有以下其他問題的建議。

我認爲最好是展示我現在使用的代碼，然後解釋我嘗試過的更多，我必須說當我注意到這一點時我正在編寫邏輯，所以現在它不工作。

還有一點MainWindow.xaml來進行測試：

<Window x:Class="PRUEBA_TABBEDEXPANDER.MainWindow" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
    xmlns:local="clr-namespace:PRUEBA_TABBEDEXPANDER" 
    mc:Ignorable="d" 
    Title="MainWindow" Height="350" Width="525"> 
<Grid> 
    <local:TabbedExpander TabStripPlacement="Top"> 
      <TabItem Header="prueba1"> 
       <TextBox Text="prueba1"/> 
      </TabItem> 
    </local:TabbedExpander> 
</Grid>

這是我的最後一次嘗試，我第一次嘗試是直接套用TabbedExpanderTabControlStyle樣式只是改變了TargetType自定義控件，那麼我就沒有加入ItemsSProperty，只是用TabControl的嘗試繼承ItemsSource具有相同的語法在「MainWindow.xaml`，並改變了語法：

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

除了<local:TabbedExpander.Items>嘗試使用TabControl的繼承Items。

唯一有效的工作是將Generic.xaml作爲ResourceDictionary合併，並將TabbedExpanderTabControlStyle直接應用於自定義控件...我認爲這不是正確的方法...對不對？因爲我將不得不將風格應用於每一個自定義控件，我將添加到我的應用程序...

我想我或者做錯了應用樣式，或使用tabitems集合，但現在我' ？m的想法:(
任何想法

通常情況下你的常規樣式添加到您的窗口（或其他高級控制）的資源字典是這樣的：

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

讓所有的孩子控件會繼承它，你試過了嗎？

請注意，現在您已經創建了自定義控件，您將希望更改樣式的目標類型，並且它將應用於應用程序中所有控件實例。（雖然看起來像你已經想到的那樣）

如果你在其他地方使用這個控件，它可能值得在它自己的文件中有樣式，然後其他項目可以將它包含在它們自己的generic/windows資源目錄中。這就是衆所周知的庫，例如MahhApps.Metro工作，例如與他們控制我的generic.xaml可能是這樣的：

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

的事情是，糾正我，如果我錯了，如果我這樣做，當我將自定義控件添加到應用程序中，我將不得不手動將樣式應用於其所有實例，對嗎？ – Nox

對不起，我按回車沒有完成評論¬¬...我認爲，自定義控件風格將自動應用於所有實例，所以我應該找到辦法做到這一點。 – Nox

不應該，不。如果你沒有指定一個鍵，那麼所有目標類型的子類將繼承這個樣式。 – Joe

TabControl的繼承CustomControl不顯示任何
