Windows 8应用商店应用:在flipview控件中使用多个RichTextColumns

Question

我正在尝试在翻转视图中以两种语言(并排)显示两列富文本。如何在RichTextColumns中创建两个列并将它们绑定到两个不同的数据源？

翻转视图控件如下所示：

` AutomationProperties.AutomationId="ItemsFlipView“x:Name="flipView”flipView AutomationProperties.Name="Item Details“TabIndex="1”Grid.RowSpan="2“ItemsSource="{Binding Source={StaticResource itemsViewSource}}">

        <FlipView.ItemContainerStyle>
            <Style TargetType="FlipViewItem">
                <Setter Property="Margin" Value="0,137,0,0"/>
            </Style>
        </FlipView.ItemContainerStyle>

        <FlipView.ItemTemplate>
            <DataTemplate>

                <!--
                    UserControl chosen as the templated item because it supports visual state management
                    Loaded/unloaded events explicitly subscribe to view state updates from the page
                -->
                <UserControl Loaded="StartLayoutUpdates" Unloaded="StopLayoutUpdates">
                    <ScrollViewer x:Name="scrollViewer" Style="{StaticResource HorizontalScrollViewerStyle}" Grid.Row="1">
                        <Grid>

                        <!-- Content is allowed to flow across as many columns as needed -->
                        <common:RichTextColumns x:Name="richTextColumns" Margin="117,0,117,47">
                            <RichTextBlock x:Name="richTextBlock" Width="560" Style="{StaticResource ItemRichTextStyle}" IsTextSelectionEnabled="False">
                                <Paragraph>
                                    <Run FontSize="26.667" FontWeight="Light" Text="ምዕራፍ "/>
                                    <Run FontSize="26.667" FontWeight="Light" Text="{Binding ChapterNumber }"/>
                                    <LineBreak/>

                                    <!--<Run FontWeight="Normal" Text="{Binding Subtitle}"/>-->
                                </Paragraph>

                                <Paragraph>
                                    <Run FontWeight="SemiLight" Text="{Binding ChapterContent}"/>
                                </Paragraph>

                            </RichTextBlock>

                            <!-- Additional columns are created from this template -->
                            <common:RichTextColumns.ColumnTemplate>
                                <DataTemplate>

                                        </RichTextBlockOverflow.RenderTransform>
                                    </RichTextBlockOverflow>
                                </DataTemplate>
                            </common:RichTextColumns.ColumnTemplate>
                        </common:RichTextColumns>

                        <VisualStateManager.VisualStateGroups>

                            <!-- Visual states reflect the application's view state inside the FlipView -->

如果这两个列要显示两个独立的信息，你能不能不做两个单独的richtextcolumn，将它们放在网格中，然后在flipview中。这样，您就可以将每个RichTextColumn绑定到您想要的源代码。
