我定义了一个类名 TextColumns.cs,它有一个 DependencyProperty RichTextBlockContentProperty:
public static readonly DependencyProperty RichTextBlockContentProperty =
DependencyProperty.Register("RichTextBlockContent", typeof(string),
typeof(RichTextColumns), new PropertyMetadata(""));
public string RichTextBlockContent
{
get { return (string)GetValue(RichTextBlockContentProperty); }
set //Debug, but the SetValue won't fire
{
SetValue(RichTextBlockContentProperty, value);
}
}
在 XAML 中,我将其用作
<FlipView x:Name="flipView"
ItemsSource="{Binding Source={StaticResource itemsViewSource}}">
<FlipView.ItemTemplate>
<DataTemplate x:Name="myDataTemplate">
<UserControl Loaded="StartLayoutUpdates" Unloaded="StopLayoutUpdates">
<ScrollViewer x:Name="scrollViewer" Style="{StaticResource HorizontalScrollViewerStyle}" Grid.Row="1">
<!-- Content is allowed to flow across as many columns as needed -->
<common:RichTextColumns x:Name="richTextColumns" Margin="117,0,117,47"
RichTextBlockContent="{Binding title}">
<RichTextBlock x:Name="richTextBlock" Width="560" Style="{StaticResource ItemRichTextStyle}">
<Paragraph>
<Run x:Name="RunText" FontSize="26" FontWeight="SemiBold" Text="{Binding title}"/>
</Paragraph>
</RichTextBlock>
</common:RichTextColumns>
</UserControl>
</DataTemplate>
</FlipView.ItemTemplate>
</FlipView>
当页面加载时,假设 RichTextBlockContent 将获取 Binding“标题”的值,而 RichTextBlock 中的 Binding 工作。
有什么我错过的吗?
