使用ItemsControl打印多页FlowDocument [英] Print Multipage FlowDocument with ItemsControl

问题描述

我正在尝试使用FlowDocument打印巨大的TreeView.为了实现这一点，我向Flow文档中添加了多个HierarchicalDataTemplates并生成页面，我只需将DataContext设置为TreeView的DataContext.当我显示此文件时 使用FlowDocumentScrollViewer看起来很完美，但是当我要打印FlowDocument时，由于我用来显示项目的ItemsControl，我总是只能得到一个页面.看来FlowDocument的DocumentPaginator无法打印 对多个页面的单一控制.有谁知道这个问题的解决方案?

I'am trying to print a huge TreeView using a FlowDocument. To achieve this I've added multiple HierarchicalDataTemplates to the Flowdocument and to generate the page I simply set the DataContext to the DataContext of the TreeView. When I display this document with an FlowDocumentScrollViewer it looks perfect, but when I want to print the FlowDocument I allways get only a single page because of the ItemsControl I am using to display the items. It seems that the DocumentPaginator of the FlowDocument cannot print a single control over multiple pages. Does anyone knows a solution for this problem?

推荐答案

The NetStriker，您好，

请提供一些代码给我们看看您是如何实现DocumentPaginator的?

PrintVisual打印任何Visual，但不能打印在页面之间拆分视觉效果.如果您希望多页打印屏幕上看到的内容，则需要实施 DocumentPaginator，然后使用PrintDialog.PrintDocument.分页器可能不得不重用视觉效果+翻译和剪切它们以模拟跨页面的断裂. 

PrintVisual prints any Visual but cannot split Visuals across pages. If you want multi-page printing of what you see on screen you'll need to implement a DocumentPaginator and use PrintDialog.PrintDocument. The paginator probably has to reuse visuals + translate and clip them to simulate breaking across pages.
