Or do I need to manually enforce this through the creation of a crude mutex of some sort? If I must enforce this myself, I'd look at creating a file in isolated storage as a lock and then deleting it on e...

Since my database has millions of rows, I want to query only the current page, but also to bring the total number of rows for paging purposes.

Hi I'm trying to get rid of the annoying "About Silverlight" context menu that pops up whenever you right click in a Silverlight application. I've added the usual ways: In App.xaml rootVisual.MouseRightButtonDown += ((s, args) => args.Handled = true); and the same for all ChildWindows. The problem that persist is in all "pop up"-c...
What I have doen has been based on this article: http://msdn.microsoft.com/en-us/library/aa348547.aspx I am trying to get a string from a merged dictionary that is loaded in app.xaml.

[1, 2] Expression Blend seems to happily support and encourage their use, though, and there are plenty of blog posts extolling the use of Triggers and Actions without any caveats. What is th...
Silverlight can use WCF, Web Services, REST based services, .NET RIA Services, but it seems like Silverlight and .NET RIA Services are preferred most. I want to know if there are any common issues [which can be a show stopper if one goes ahead with this combo] that you have seen in practical implementation of SL with .NET RIA Services. ...

I'm trying to avoid the default Silverlight loading screen displaying before my applet and was trying to show a blank coloured background, the same colour as my applet's. The aim is to avoid the jarring white and make it look like it's all part of one app drawing. I've discovered SplashScreenSource but I'm not sure how to hook that up ...

In order to debug I'd really like to be able to capture the debug/trace information output by the app. (The problem is in in code running in a background thread so outputting debug information to the screen isn't practical and risks creating new issues.)
