使用DataTemplate的FlowDocument [英] FlowDocument using DataTemplate

问题描述

我想在流程文档中创建页面，在该页面中将使用DataTemplates添加页面.我试图通过将ViewModels实例添加到ItemsCollection中来在FlowDocumentScrollViewer中托管的flowDocument中具有ItemsControl. 我遇到的问题是

I want to create pages in a flow document where the pages would be added using DataTemplates. What I tried was to have an ItemsControl in a flowDocument which is hosted in a FlowDocumentScrollViewer by adding instances of ViewModels to the ItemsCollection. The problem I am having is

1.我该如何将段落保存在DataTemplate中?

1. What do I use to hold the paragraphs in a DataTemplate?

 例如:在下面的DataTemplate中包含两个段落的元素应该是什么?

  for eg: What should be the element that holds both paragraphs in the below DataTemplate?

  < DataTemplate DataType = {x:Type MyPage1}>

  <DataTemplate DataType={x:Type MyPage1}>

      < Paragrah BreakPageBefore ="True">

      <Paragrah BreakPageBefore="True">

        .....

        .....

      </Paragraph>

      </Paragraph>

       < Paragraph>

       <Paragraph>

       </Paragraph>

       </Paragraph>

  </DataTemplate

  </DataTemplate

2.除了使用ItemsContainer之外，还有一种更好的方法来执行此操作，以便渲染后我可以将其看起来像单独的页面.

2. Instead of using an ItemsContainer is there a better way to do this so that I can have it look like seperate pages once it is rendered.

添加所有页面后，它应表现为单个文档的页面.

After I add all the pages, it should behave as pages of a single document.

谢谢

据我所知，没有内置的方法可以处理此问题，建议您阅读本文:

As far as I know, there is no build-in way to handle this, I would suggest you reading this article:

作者创建了自定义的Section类: ItemsContent ，用法:

The author created customized Section class: ItemsContent, the usage:

<FlowDocumentScrollViewer>
            <FlowDocument>
                <flowdoc:ItemsContent ItemsSource="{Binding Source={StaticResource DataSource},XPath=NorthwindNames/Person}" >
