使用的ContentTemplate我有自定义ContentControl中所谓的TabItem自ContentControl中不会从资源字典
public class TabItem : ContentControl
我已设置的ContentTemplate到动态资源从资源字典
<TabItem Header="Search" Content="{Binding Path=SearchRibbon}" ContentTemplate="{DynamicResource SearchRibbonTemplate}" />
未来使用这种方法我我正在利用MVVM设计模式，并且Content属性成功绑定到视图模型...并且程序成功构建并运行，但没有来自内容模板应该拉入的数据模板内的内容。
<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>
如果我按照原样使用内容控件，则此方法一直有效。为什么自定义contentcontrol不能用于ContentTemplate属性？
干杯。

您确定使用名为'TabItem'的自定义项目而不是内置的'TabItem'控件吗？标签应该看起来像''。另外，什么是'SearchRibbon'？如果它不是一个可枚举的集合，那很有可能你的ItemsControl没有找到任何要渲染的项目，所以最终的结果是什么都不显示。 –

您绑定到内容的对象的类型是什么？ – 2012-07-10 14:30:27
从技术上讲，您不必为您的自定义命名空间@Rachel设置自定义名称;） – Kolky 2012-07-10 14:32:12
