从视图下载附件 [英] Attachment download from view

问题描述

是否有一种方法可以在视图控件(或重复控件)中列出所有文档，并具有下载按钮/链接，使用户可以下载驻留在RTF文本字段中的多个附件?

Is there a way to list all documents in a view control (or a repeat control) and have a download button / link that will allow the user to download multiple attachments that reside in a rich text field?

我已经找到了使用@AttachmentName的选项，但这会列出文档中的所有附件，并且不会将附件限制为仅一个RTF.

I have found options using the @AttachmentName, however this lists all attachments on the document and does not restrict the attachments to just one the RTF.

我有一个使用对话框的解决方法，该对话框效果很好，只是没有我想要的选项干净.

I have a work around using a dialog box, which does work well, just not as clean as the option I was looking for.

推荐答案

在视图中，您可以具有计算列.您放置在对话框中的任何代码都可以放置在计算列中. XSPviewEntry的getDocument()方法使您可以访问文档(明智地循环使用).

In a view you can have a computed column. Any code you place into a dialog could be placed into a computed column. The getDocument() method of the XSPviewEntry gives you access to the document (recycle wisely).

更新

要使用下载控件，请对数据源使用重复的视图，并在每行使用一个面板.面板上的数据源指向文档.使用tr作为面板的标签.

To use a download control, use a repeat with the view as datasource and a panel per row. The panel has the data source pointing to a document. Use tr as tag for the panel.

仅当您不想在其他字段中显示附件时才需要

This is only needed if you have attachments in other fields you don't want to show
