Silverlight TabItemの内容がスクロールしない

Question

私はこのXAMLを使用して、TabItemの内容をスクロールさせようとしました（成功なし）。

<ex:TabControl> 
    <ex:TabItem Header="General"> 
    <ContentPresenter Content="{Binding }" ContentTemplate="{StaticResource tabMenuItem}" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto" /> 
    </ex:TabItem> 
    <ex:TabItem Header="Prices (Item)"> 
    <ScrollViewer VerticalScrollBarVisibility="Visible" HorizontalScrollBarVisibility="Auto"> 
     <ContentPresenter Content="{Binding NonModifierPricesView}" ContentTemplate="{StaticResource tabMenuItemPrices}" /> 
    </ScrollViewer> 
    </ex:TabItem> 
</ex:TabControl> 

のTabItemはすべてのコンテンツを表示するには小さすぎるように私のTabControlのサイズが変更されても、何のスクロールバーは表示されません。私はどこかで何か間違ったことをしましたか？

のために要求XAML ScrollViewerのの子は、それが自分の高さと幅です管理する必要があります。それはストレッチの値をデフォルトですので、あなたのContentTemplateであなたの最も外側のグリッドがたHorizo​​ntalAlignmentまたはVerticalAlignmentをを指定していない...あなたは次のように左と一番上にアライメントを設定してみてくださいすることができます

<Grid HorizontalAlignment="Left" VerticalAlignment="Top"> 

一番下の行は、ありますコントロールテンプレート内の一番外側のコンテナは、親コンテナではなく、コンテンツの高さと幅を設定する必要があります。
