It's using WCF RIA Services with Entity Framework. But it didn't seem to help me, what am I missing, or why is my scenario different? Note: If I put a TextBox (not inside the UserControl) in my main page, it shows validation error. This is my UserControl code: <UserControl x:Class="TestApp.MyUserControl" xmlns="http:/

Html:- <object ....> <param name="onload

问题 I've come across a weird discrepancy between BigInteger s used by .Net 4.0 and Silverlight 4.0; In .Net, BigInteger has a Parse and TryParse method where as in the Silverlight version, it does not have either of these. If you look at the .Net version of System.Numerics in Reflector, you also see that when you disassemble the code, every single method is just empty, and it lacks the BigIntergerBuilder and friends of the Silverlight version: public static BigInteger Parse(string value) { } What

问题 I am designing a image editor in silverlight 4.0 Looking for typing text along curvature path like circular or arc Something similar to what is available in photoshop http://youtu.be/6L6qAKkBQxc Is there any code snippet available on this?

问题 I'm planning to build a download manager application and would like to be able to launch the application when a user clicks a button the site. The application would obviously already need to be installed on the client machine. There are a few reasons why this needs to be written using Silverlight, but they're not really relevant to the question. I only mention it so that people don't suggest that I use another technology. 回答1: I think that is not possible according to this post post 1 and to

问题 I've spent a good while this afternoon trying to implement the deserialization of JSON within a string, at first I was using DataContractJsonSerializer as my environment is Silverlight however it does not appear to support using a Dictionary out of the box (Raised in many other SO questions).
