These guys are the experts

But my problem involves a Silverlight 4 RIA Services application which utilizes Windows Authentication and needs to run or operate as an out of browser application. The application must obtain detailed or descriptive user info in order to correctly construct the initial application user interface. However, the dilemma is that the Authentication Service call was timing out every time I executed the application, and my RIA Service was never even executed.

So if I can receive any help, then that will be great from the blog readers, then that will be great.

Can you explain how to do the hiding links / menu items as promised above?

Many Thanks,

Shane

The Refresh command helped to solve my problem to enforce navigation after login. Simple but perfect.

Please accept my apologies for not checking your downloads page for a more recent build of SLaB prior to sending my previous email. I subscribed to your blog, and assumed there would be an article to follow a new release. I check your home page periodically, but usually not the downloads. 

At-any-rate, here is a link (below paragraph) to your Sitemaps.xaml file with a very small change (with comments). If you replace your Sitemaps.xaml file in the ScratchContent project with the one provided in the link below, hit F5, you’ll notice that the browser hangs and is non-responsive for about 7.976 seconds. The progress bar is visible, but motionless.

The small change in the Sitemaps.xaml file is simply an addition of a few more Sitemapnodes. To continue, adding only a few more nodes magnifies the hang-time by ^2. (Please see comments in Sitemaps.xaml file to see a longer hang-time)

In my previous email I mentioned where I believe this problem exists. Do you get my last email regarding the BreadCrumNavigator? I can resend it if need be.

Is there any chance you might be able to take a look at the BreadCrumNavigator & the SLaB.Utilities.ChangeLinq project to see where the performance can be improved? I will be forever grateful. Just to recap, the TreeViewNavigator is perfectly fine, that is, it doesn’t override the OnTrimmedSitemapChanged method. I really want to use the BreadCrumNavigator, however, the size of the Sitemap I am producing can range anywhere from 10 nodes to 200 nodes. The original Sitemap.xaml file in your sample project only has 27 Sitemap nodes.

Again, I Just wanted to say a huge thank you for providing some awesome libraries to aide us all with SL development. They have saved me a lot of dev time.

I look forward to hearing from you regarding the Sitemap size / performance problem with the BreadCrumNavigator.

Sincerely,
