Greg, not 100% sure about SL as I am more WPF worldly, but I would think you'll
likely need to programmatically assign the appropriate ResourceDictionary(s)
after login.
something.Resources.MergedDictionaries.Add(somesource.GetResourceDictionaryForUser());
where 'something' is your app or a particular window or control etc. and
'somesource' is either assembly internal as in Resource files, or a WebService
proxy etc?
If its a Xaml string from a Web Service you may need to use SL's equivalent of
the XamlReader class to read in the String and cast to a ResourceDictionary as
follows (at least for WPF):
ResourceDictionary rd = XamlReader.Load(s) as ResourceDictionary;
(rd != null)
{
//etc, etc
}
Hope this helps,
Dan.

Subject: Dynamic themes and resources
Folks, it's an action-packed day, I just received word that my SL3 app will
soon need to have a feature to assign a different appearance and different
string resources according to who is authenticated (via the initial login
screen).
I took precautions to allow the app to have a different appearance and strings
in different installations, but I wasn't really prepared to cater for the more
granular approach of changing appearance for different logins.
The strings are all in a spreadsheet-style resource file, so that's only a
minor problem for me. However, dynamically changing themes is more frightening
as I haven't needed to do that before. I've tried to be neat with my styles and
put them in the controls or in the App page, but I feel that to get dynamic
themes in Silverlight I will have to be ultra-strict and use clever binding.
I'm just not sure of the best way to structure the styles and templates
globally within the app to make theming easier. I'm going to search to web
article guidance on this, but I'm keen to hear from anyone who's done this
before and has some tips and tricks to share.
Cheers,
Greg
