silverlight-3.0

Has anyone written an event log that uses Isolated Storage in Silverlight 3? Any suggestions on implementing one? Specific questions: Should I keep a stream writer open, or should I open,write, and close for each entry? How should I remove items from the log atomically? I heard clog from codeplex is pretty good although it targets wcf, i read on codeproject about about a log4net approach that works for silverlight, although both of these log 2 wcf services, im sure with a bit of tweaking you can modify this to write to isolated storage Crypto Logger supports Silverlight apps and libraries and

I have a object that implements the IEditableObject interface exposed on a viewmodel bound to a Silverlight page. How/Where do I call the BeginEdit, CancelEdit and EndEdit methods? How can I constrain only objects implementing this interface to my page? I am NOT using DataGrid or DataForm controls. I am using Label, TextBox and DescriptionViewer controls to display the data for editing. I know this is an old thread (but for the sake of future use...) I do it this way: whenever the current item (for instance of a CollectionViewSource) changes this is done: void View_CurrentChanged(object sender

I am having trouble upgrading my current project to use RIA Services. I added all the necessary web.config changes but still no luck. I everything compiles fine but when I hit the page using the datacontext I get an error. I debugged with fiddler and I'm getting a 404 on one of the request. I am getting back headers in my grid so some communication is happening but no data is actually coming through. Another thing to note is that my MVC is running windows authentication. I do have a clientaccesspolicy.xml as well. Error in Silverlight with Headers but no data, Response from Fiddler:

How would one go about styling a listbox such that the selection has a different text color than the default view? I've looked at this in several ways and because the ContentPresenter lacks a Foreground property. The default control template of the listbox provides several rectangles which one can use to adjust the highlight color. For example, with the default style a rectangle called BGColor3 has its opacity adjusted to get a highlight effect. Here is the bulk of my control template: <Grid> <Rectangle x:Name="BGColor2" Fill="{StaticResource HoverBrush}" Stroke="Black" StrokeThickness="1"

How can you use Dynamic Language Runtime (DLR) or something else to mimic System.Dynamic.DynamicObject in SILVERLIGHT 3 (!) and WP7 (no C# 4.0!).. What I want to do is implement automatic dynamically created properties for databinding. The DLR can be used with WP7. Iron Ruby supports Windows Phone 7 from version 1.1 . DynamicObject was available as an extension prior to .Net 4.0 If you're happy using a language other than C# then this could be an option. There's a good article on using IronRuby on Windows Phone 7 at http://msdn.microsoft.com/en-us/magazine/ff960707.aspx . As an alternative,
