I am getting a run-time error when I use DataBinding, and it is driving me crazy. I have a simple UserControl that I have defined, let's call it SillyControl. Separately, I have a collection ObservableCollection<MyClass> myObjects; and a ListBox called SillyListBox which is bound to this ObservableCollection via: SillyListBox.ItemsS...
In an MMVM application, how should exceptions be handled and bubbled? If I get an exception in my model, during an Async callback, and throw an exception, this does not get bubbled to the ViewModel. I suspect that this is because the callback is not running on the UI thread. What's the best practice for this? Mark ...
I was wondering if any of you had successfully implemented DDD in a Client/Server app and would like to share some experiences. We are currently working on a smart client in Flex and a backend in Java. On the server we have a service layer exposed to the client that offers CRUD operations amongst some other service methods. I understand...

I make calls to a webservice to get information that bind to the Text property of a TextBlock. Sometimes the information will contain encoded special characters for HTML - most notably the ® which I believe to the (r) symbol. The silverlight TextBlock just displays the raw text and not the (r). Of course, I can strip out the text, but...

I am working on a typical data entry system in Silverlight. Most of my screens are basically view/edit screens. I am using a DDD approach and have domain objects for everything. A typical scenario is something like a User object with a user edit and entry page. After working on this for a few types of objects, I am seeing a pattern...
I have a thick GUI application (possibly running as a service, but also just as a normal application) on a desktop. I would like to expose a web interface to the application for some remote monitoring and control of the application. I currently am hosting a WCF service that just returns HTML in the application, which works fine, but opt...

I have writen a small applet in Silverlight and, while it works fine on Windows, it seems that on OSX the data binding part of the application (all those NotifyPropertyChanged calls) do not work.

I am intending on learning WPF and Silverlight to the extent of its advanced details. What book is good for taking a practical approach to Silverlight?

I'm working an project (pure hobby, "Sharping my skills") which has one unified back-end and multiple front-ends (ASP.NET MVC 1.0/JQuery and Silverlight 2). When I try to add reference to my business layer assembly in the Silverlight 2 project (VS2008); It gets rejected, because it's not a Silverlight assembly. Is their a way to include...
I mean the small exit/cancel button marked with an X in the top right hand corner. I want to implement a Logon dialog box that accepts a username/password so obviously I don't want the user to be able to dismiss the modal pop up.

I was wondering if anyone has gone through a process of picking a 3rd party library for Silverlight components? The major offerings I know of thus far come from Telerik, ComponentOne, and Infragistics. Rather than make this all negative can I phrase the question specifically as the following: a) Which 3rd party Silverlight components h...
My silverlight application loads data fromt he SQL fine when I build locally but when I upload it to the live site it will just wait for data to be loaded but show no errors.
