自ContentControl中不會從資源字典

使用的ContentTemplate我有自定義ContentControl中所謂的TabItem自ContentControl中不會從資源字典

public class TabItem : ContentControl

我已設置的ContentTemplate到動態資源從資源字典

<TabItem Header="Search" Content="{Binding Path=SearchRibbon}" ContentTemplate="{DynamicResource SearchRibbonTemplate}" />

未來使用這種方法我我正在利用MVVM設計模式，並且Content屬性成功綁定到視圖模型...並且程序成功構建並運行，但沒有來自內容模板應該拉入的數據模板內的內容。

<DataTemplate x:Key="SearchRibbonTemplate"> 
    <ItemsControl ItemsSource="{Binding}"> 
     <ItemsControl.ItemTemplate> 
      <DataTemplate> 
       <TabGroupBox Header="{Binding Path=DisplayName}" Width="100"> 
        <TabButton Width="100" Icon="{Binding Path=TemplateResource}" LargeIcon="{Binding Path=TemplateResource}" Command="{Binding Path=Commands}" /> 
       </TabGroupBox> 
      </DataTemplate> 
     </ItemsControl.ItemTemplate> 
    </ItemsControl> 
</DataTemplate>

如果我按照原樣使用內容控件，則此方法一直有效。爲什麼自定義contentcontrol不能用於ContentTemplate屬性？

乾杯。

您確定使用名爲'TabItem'的自定義項目而不是內置的'TabItem'控件嗎？標籤應該看起來像''。另外，什麼是'SearchRibbon'？如果它不是一個可枚舉的集合，那很有可能你的ItemsControl沒有找到任何要渲染的項目，所以最終的結果是什麼都不顯示。 – Rachel 2012-07-10 14:30:04

您綁定到內容的對象的類型是什麼？ – 2012-07-10 14:30:27

從技術上講，您不必爲您的自定義命名空間@Rachel設置自定義名稱;） – Kolky 2012-07-10 14:32:12

與該建流利絲帶庫，我改造的開發商一一對應後，他指出，爲了實現這樣的設計會花費更多的然後就修改ContentPresenter和一個完整的返工會必要。在這種情況下，他曾建議建立一個ViewModels列表，它可以提供我期待的設計。

感謝大家的回答，但困難的方式似乎是這種情況下的簡單方法。

乾杯。

我的猜測是，你沒有定義默認樣式在Themes/Generic.xaml控制應控制的Template設定爲至少包含一個ContentPresenter。

例如

<Style TargetType="local:TabItem"> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="local:TabItem"> 
       <!-- Usually there is also a Border which template binds the Margin, Padding, etc. --> 
       <ContentPresenter /> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style>

我有一個ControlTemplate的樣式的模板屬性的值...你說這應該是一個ContentPresenter，而不是？ – bl4kh4k 2012-07-10 14:42:08

@ bl4kh4k：我說ControlTemplate需要包含一個ContentPresenter，否則內容將不會顯示。此外，ControlTemplate上的TargetType需要使ContentPresenter綁定到相應的屬性。 – 2012-07-10 14:44:35

嗯，所以我確實在ControlTemplate中有邊框和網格，所以我應該在ControlTemplate的結束標記之前放置？我不明白爲什麼這個工作？ – bl4kh4k 2012-07-10 14:46:20

自ContentControl中不會從資源字典
