I want to add a state called TextBlock and I want the VisualStateManager to go to that state when the IsTextBlock property/dependency property is true.

Analysing log files I've noticed that ~1% of service calls ended with TimeoutException on the Silverlight client side. The services (wcf) are quite simple and do not perform long computations. According the log all calls to the services are always processed in less that 1 sec (even when TimeoutException is occurred on the client!), so it...
The docs for Silverlight's IsolatedStorageFile.GetUserStoreForApplication just say that the isolated storage is specific to the "application", and that each different application will have its own storage independent of all other "applications" (but with one quota for the entire domain). That's great, but I haven't found anything yet th...

I need to make sure certain essential data are loaded before a module is loaded and shown on screen. considering the async nature of data loading in silverlight, I was wondering if there is a pattern I should follow to load my data (like an event on the module or the bootstrap to hook into, or a method to override)... ...

I'm looking for a solution for capturing audio from a user's microphone and posting it (preferably as MP3) to a server. I need something that I can embed in a web page.

However, since the silverlight app ...

How do you determine the width of the text in a WPF TreeViewItem at run time? I need to calculate an offset so I can draw a line from one leaf to the leaf of a different TreeView. All the 'width' properties return a size that is way bigger than the space taken up by the actual text of the node. It must be possible because the Select f...
