There is a lot of effort in the Silverlight community to keep a XAML's code behind file as free of code as possible. What is the real motivation behind this? For example, what is the advantage of using a command instead of an event handler? If I have <Button x:Name="SaveButton" Content="Save" Click="SaveButton_Click" /> ... private...

In this thread from a year ago it's explained that WriteableBitmap will block read access when any part of it comes from an outside domain - say a free image server. It's further elaborated upon that this is for "DRM". I guess there's some big threat of someone writing a movie-ripper in Silverlight that includes a movie from another do...

So why it is possible to access an object of class System.Windows.Threading.Dispatcher which is associated with the main UI thread from other worker threads when we want to delegate some work to be done on the User Int...
I'm fairly new to Silverlight but experienced in web development, and I'm finding myself highly annoyed with Silverlight's default combobox. It seems to be lacking any concept of use for regular data entry. Primarily I'm wishing it would function like an HTML select box, where you can hit the drop down, then type a letter and it takes yo...

I'm creating a simple messaging system for a windows phone silverlight app. The idea is various xaml pages & other objects will subscribe to a messaging object, passing in the type of message they want to recieve/handle and an Action<> Delegate as the handler. When an action happens a message (with payload) will be sent to the correct ...
The following code works for stretching the child Grid within the ListBoxItem in Silverlight 3, but not in Windows Phone 7. Is this a bug or am I doing something wrong? No matter what element I put in the ListBoxItem, it never grows to the size of the ListBoxItem, only to the size of its own content. My end goal is to get the text to ali...
I have a Silverlight application which uses 2 separate databases. I have a situation where I have an Id column in one database, and the lookup table in another database. Obviously I cannot enforce this as a foreign key, and the Entity Framework will not let me build a single Entity Data Model for 2 databases, so I cannot define this rela...
I'm new to Silverlight programming, and the DependencyProperty is still relatively new to me, which causes the following issue: I'd like to attach to an event, when Canvas.LeftProperty of Canvas.TopProperty changes for an UIElement (a UserControl in my case). For example, I'm able to do the following: source.SizeChanged += del...
