Hello! I'm using WCF RIA + Silverlight 4.0 in my project. On client and server side I need to check (via validation process) if collection (e.g. Orders) that belongs to e.g. Manager is filled or not.

I am a bit confused about the difference between Silverlight and Expression Blend. From my understanding, Silverlight is used to create a better interface, and Blend is used to create animations? Meaning you can use Silverlight without having to use Expression Blend (there is much demand for Silverlight developers, but I from what I know...

I have an odd problem in silverlight. I use the following XAML to bind the content of a label to a double property in my viewmodel. Content="{Binding FeePeriodActual, Mode=OneWay,StringFormat=\{0:c\}}" However, the display string always shows the $ Dollar Currency symbol rather than the the £. This is the same on the production serv...

I need to create a fairly complicated layout for a widget in Expression Blend, with the visual design not yet set to stone, while having fairly refined functional wireframes. So I started to lay out the UI controls and choosing layout structures based on the wireframes, but as far as I have seen so far while experimenting, PSD files wil...
I've looked at the Drop and ItemDroppedOn Target event handlers but it appears that you can only access the source. The sender is the TreeViewDragDropTarget when I actually want to see the item in the TreeView that is being dropped on. ...

While all of my machines are Macs, I actually really enjoy working in .NET. I thought it would be fun to try my hand at writing a Silverlight application. Unfortunately, as near as I can tell, Silverlight is not a part of Mono that actually works on OS X. Is it possible to develop Silverlight on OS X, or will I need to use a VM? If it's...

Hi guys, Is it possible to change (maybe there is a T4 hidden somewhere...) the way Silverlight Ria Services generates the Domain Contexts classes? I would like to add an interface to them so my ViewModels can use the interface instead of the class making them more unit testable. Tks, André Carlucci ...
