TabItemというカスタムContentControlがあります

public class TabItem : ContentControl

ContentTemplateをリソースディクショナリからの動的リソースに設定しました

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

このアプローチを使用して、MVVMデザインパターンを利用しており、Contentプロパティがビューモデルに正常にバインドされています...プログラムは正常にビルドされて実行されますが、コンテンツテンプレートが取り込む必要のあるデータテンプレート内のコンテンツはありません。

<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>

コンテンツコントロールをそのまま使用すると、このアプローチは常に機能します。カスタムcontentcontrolがContentTemplateプロパティで機能しないのはなぜですか？

乾杯。

私が刷新している Fluent リボン ライブラリを構築する開発者の 1 人と連絡を取った後、彼は、この設計を実現するには、単に ContentPresenter を変更するだけではなく、完全な再作業が必要になると指摘しました。この場合、彼は、互いのコントロールから派生する ViewModel のリストを作成することで、私が探しているデザインが得られると提案しました。

みんなの答えに感謝しますが、このシナリオでは難しい方法が簡単な方法のようです。

乾杯。

私の推測ではThemes/Generic.xaml、Templateコントロールの に少なくともContentPresenter.

例えば

<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>
