Silverlight 4 in Action
Silverlight 4 in Action (Manning, Pete Brown) – this is second book, which I read about Silverlight. First was Pro Silverlight 3 in C# (Apress, Matthew MacDonald), which helped me when I was need to very quickly know more about Silverlight after WPF. After reading Silverlight 4 in Action I think that this is best book about Silverlight. But maybe I should compare this book with Pro Business Applications with Silverlight. -

Silverlight basics. Validation. Part 1. DataAnnotations & ValidatesOnExceptions
Silverlight 4 has some new ways for validate input values (some new approaches to implement validation in your application). First approach is DataAnnotation. In this case you should describe validation rules with attributes. Two other ways (both of them is came with Silverlight 4) – you should implement one of interfaces for your ViewModel: IDataErrorInfo or INotifyDataErrorInfo. I want to talk about all of these approaches, about pros and cons of using each of them. Goal of this article to get a best way to implement validation of input values in my and your applications. This part of article about DataAnnotations.

RESTful WCF Service – How to get browser version at server code
At our product we have a client Silverlight part and server-code part, which contains a lot of WCF methods. We don’t use ASP.NET Compatible mode, because we want to leave an opportunity to deploy server part to server without web-server role (without IIS). Really, I don’t know why we chose this way, because all of our installations at current moment are on IIS. But we have what we have, so we haven’t ASP.NET Compatible mode, and as an expected result we can’t get HttpContext.Current instance at server WCF methods. One of WCF Service is a RESTful service, which at his methods returns report files, so it can handle GET-queries from browsers. Read more...

Export data to Excel from Silverlight/WPF DataGrid
Data export from DataGrid to Excel is very common task, and it can be solved with different ways, and chosen way depend on kind of app which you are design. If you are developing app for enterprise, and it will be installed on several computes, then you can to advance a claim (system requirements) with which your app will be work for client. Or customer will advance system requirements on which your app should work. In this case you can use COM for export (use infrastructure of Excel or OpenOffice). This approach will give you much more flexibility and give you possibility to use all features of Excel app. About this approach I’ll speak below. Other way – your app is for personal use, it can be installed on any home computer, in this case it is not good to ask user to install MS Office or OpenOffice just for using your app. In this way you can use foreign tools for export, or export to xml/html format which MS Office can read (this approach used by JIRA). But in this case will be more difficult to satisfy user tasks, like create document with landscape rotation and with defined fields for printing.
