In my quest to develop a pretty data-driven silverlight app, I seem to continually come up against some sort of race condition that needs to be worked around. The latest one is below. Any help would be appreciated. You have two tables on the back end: one is Components and one is Manufacturers. Every Component has ONE Manufacturer. ...
A call from a Silverlight 2.0 control to a WebService, returned via MyWebServiceNameEventArgs is not returning contained List<> aggregates.

I'm having a problem with this this XAML... When I run it, it hangs because of the TextBox. (By "hangs" I mean that the hosting aspx page shows in the browser, but the usercontrol object will not appear on the page, and there are some little green bars in the bottom of the Internet Explorer window that fill up but never go away.) I hav...

Hi, I am trying to implement a Silverlight 2 client application that takes data from a server via socket-based communication. I've heard that in Silverlight 2, this process is more complicated due to the fact that it is required to use a policy server, and that could slow down my application, not to mention that each string passed throu...
Sorry if this is generic in nature, but I have a question that maybe is related to my lack of understanding of some core underlying rules of .NET and Silverlight. I have a basic project at the moment that simply: An ASP.NET generic handler writes out XML Within Silverlight, I am using the WebClient object to get the XML output, in fac...
I'm building a custom control in Silverlight by deriving from ContentControl and doing some special formatting to put a dropshadow behind the contents. I've nearly got it working but have recently ran into a bizarre error. It works fine if it contains anything besides a Border, or a Grid/Stackpanel/etc that does not have an explicitl...
When a MessageBox is being displayed from Silverlight, any calls to a WCF service being executed in a BackgroundWorker are blocked. The OpenFileDialog.ShowDialog allows these calls to go through.

The client is using WinXP + IE7 and has the SL2 runtime installed. On the client's machine the following error pops up: Error: Unhandled Error in Silv...

I w...
I am trying to create a custom panel that utilizes absolute positionioning but will re-arrange items so that none of the children overlap. This panel will be used for the ItemsPanel of an ItemsControl. The ItemsControl is bound to data that is displayed as an inset on a map for various cities so the goal is to keep the insets as close to...
Hello: I'm pretty mightily surprised and sheepishly stumped: Have a new UserControl backed by UserControl01.cs that is exposing two properties. One is a plain old CLR property, the other the newer DP property format. eg: string PropertyOne {get;set;} and the second property is a public DP (construct is too long to list here). From ...
