It works great. Thanks. But I turned my forms authentication back on and now the load on demand page's web services don't work. The pages still load okay but the web service calls fail. The load on demand pages exist in sub folders on the web server and each page has its own web config and web service. Any ideas? Thanks, Michael Hi David,

It's all extensible and doesn't have to be defined in XAML -- this is just the experience I chose for the 90% case. If you run into something that's broken with it, please do let me know :) As for your second issue, it really depends on what their content is. If users are using the RichTextBox control to generate content, for example, you might store the XAML they generate directly into a database (just as a string) and use XamlReader.Load() on the content to pull it back out. I actually have a richer example of this here: http://www.davidpoll.com/2010/07/25/to-xaml-with-love-an-experiment-with-xaml-serialization-in-silverlight/ If the RichTextBox only has plain inlines (e.g. Hyperlinks, Runs, Bolds, Italics, etc.) and nothing richer (e.g. Images, inline UI, etc.), then you can just use the .Xaml property of the RichTextBox to get the XAML back out. Otherwise, the UiXamlSerializer in my post above may be able to help. I hope that helps! -David Sagar,

As for rebuilding, I've seen this error before (it happens to me occasionally too). I've found that usually closing the TestPrinter.xaml file resolves it. I'm still not sure why it's happening, since all of the dependencies are indeed there. The CreateExtmap task is there to generate the extmap files for all of my assemblies. It's not an after-build event so that I can easily reuse it without being fully dependent on file paths, etc. It was just the solution I ultimately chose :). You can remove the task and things should still build correctly, although I'm not sure why you want to get rid of them. Anyway, I hope that helps! -David Wolf,

We have two issues one related to SL navigation and another general concept. We need ur suggestion. Issue 1#: We need to generate the menu and submenu at run time depending on user role. User role name and pages(URL) they can authorize to access are being defined in database( we have separate interface for that). On login we need to read the database and generate menu/submenu according to role of the user. What is best option to do this in SL. Issue 2#: Second issue is general architectural concept. What is best way to store article submitted by user while developing a community site. Please share your knowledge and useful link to solve our problem and help us to develop a robust Sl application): Thanks Sagar Hi,

I tried to rebuild your SLaB solution and had no problems, however, when I delete the extmap.xml files (clean doesn't remove these) I am getting errors during the rebuild. After a few cycles of rebuilds the errors clear up. To duplicate I delete the .extmap.xml file in SLaB\Source\SLaB.Navigation.ContentLoaders\Bin\Debug then rebuild and I get: Error 1 The type or namespace name 'CollectionPrinter' could not be found (are you missing a using directive or an assembly reference?) C:\Users\Wolf\Documents\Visual Studio 2010\Projects\Samples\Navigation\SLaB\Source\ScratchPrintingProject\obj\Debug\TestPrinter.g.i.cs 36 40 ScratchPrintingProject I looked at the project file and the only cause I can see is related to the CreateMapExt "using task". I am not sure what this actually does, can you please explain? Also is there a reason why this is a using task versus a 'After Build' event? Thanks, Wolf Hi David,

I would really like to use your method of printing a document, but I can't figure out how to properly group the items and still have the printer create multiple pages when needed. It's as if it doesn't know that it has reached the bottom of the page. Please, if you are not too busy I would really appreciate some further information regarding grouping.
