Hi Steven I wrote an article (for Silverlight 2, but still valid), which covers creating an IFrame and displaying HTML/PDF/Word/etc inside it using their browser plugins: www.silverlightshow.net/items/Building-a-Silverlight-Line-Of-Business-Application-Part-6.aspx. To me, it does look as though it's a part of the application (assuming the user has the corresponding plugin installed). It resizes with the browser window, and you get all the functionality of that plugin (particularly printing). Alternatively, check out the Document Toolkit from First Floor Software (by Koen Zwikstra, of Silverlight Spy fame): http://firstfloorsoftware.com/documenttoolkit. It displays XPS, and he discussed displaying PDF using it too (not sure on the status of that though). Check out my example anyway too, and see what you think. I also discuss this topic (primarily in regards to reporting) in my upcoming book Pro Business Applications with Silverlight 4 (for Apress).
In terms of displaying RTF, you might want to look at some open source RTF parsers in C# like: http://www.codeproject.com/KB/string/nrtftree.aspx http://www.codeproject.com/KB/recipes/RtfConverter.aspx I'm sure it would take little (or no) effort to port to Silverlight. Hope this helps... Chris On 15 May 2010 08:52, Steven Nagy <[email protected]> wrote: > You’re right to a degree. We get stuff in a variety of formats from > different systems.
