HTML编辑器ASP.NET中的HTML到PDF [英] HTML to PDF from HTML Editor ASP.NET

问题描述

我需要创建一个由多个页面组成的PDF。整个内容需要在HTMLEditor中显示，以便可以编辑并保存为PDF格式。



我使用的是Visual Studio 2012和C＃。



我面临的问题是HTMLEditor存在浏览器兼容性问题。用户将通过HTMLEditor更新HTML的内容，并将其保存为PDF。由于用户更新了内容，我无法使用iTextSharp。任何解决方案都会有所帮助。



问候，

I need to create a PDF consisting of Multiple pages. The entire content need to be displayed in HTMLEditor so that it can be edited and saved as PDF.

I am using Visual Studio 2012 and C#.

The problem I am facing is HTMLEditor has browser compatability problem. The user will update the contents of HTML via HTMLEditor and will save it as PDF. Since the user updates the content I am not able to go for iTextSharp. Any solution will be helpful.

Regards,
Bala
