Question

すべて正常に動作するデータ テンプレート内のさまざまなボタンの複数値コンバーターに同じ値を渡すシナリオがあります。しかし、同じコンテンツを

<telerik:RadButton.Visibility>
    <MultiBinding Converter="{StaticResource multiValueToBooleanConverter}" ConverterParameter="ViewCommentsDialog">
        <Binding Path="DataContext.CanEdit" RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type UserControl}}" />
        <Binding Path="DataContext.CanView" RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type UserControl}}" />
        <Binding Path="Comment"/>
        <Binding Path="ExecutionId"/>
    </MultiBinding>
</telerik:RadButton.Visibility>
