Hi,
the following code works fine and bind records with grid.

EmployeeDomainContext employeeDomainContext = new EmployeeDomainContext();
employeeDomainContext .Load(employeeDomainContext .GetEmployeeQuery();
dgrEmployee.ItemsSource = employeeDomainContext.Employees;

But if I want to get records from employeeDomainContext.Employees then I am not be able to get these records, even it shows its count to 0.

Can I get these records in a variable?

Thanks and Best Regards,
Hafiz Muhammad Suleman

Demo won't compile claims it needs system.web.silverlight which does not ship with 3.0.

hi there,

It seems that this article has not included the pre-requisites or requirements in order to run Silverlight 3 + RIA Services on a server. Therefore, I have a couple of things to add and the followings are stuffs that must be installed on the server:

1. .NET3.5 Framework
2. Full Trust mode must be enabled
3. Install the Visual Web Developer 2008 tool
4. Install the Visual Studio 2008 Service Pack 1
5. Run the Silverlight 3 Toolkit
6. Run the RIA Service Installation
7. Silverlight can run on either IIS6 or IIS7

I am currently hosting my Silverlight 3 (+ RIA Service) with ASPHostCentral (http://www.asphostcentral.com/) and so far, everything works smoothly. To be honest, there are so many exciting things about this latest Silverlight 3, with an exceptional extra feature of RIA Services. I am still exploring further features, which include Expression Blend and hopefully, I can see more interesting articles here :)

Thank you for the article! Silverlight and RIA Services are so exciting!!

So far, the one thing I can't find any information about is CRUD to the server file system through RIA Services.

I have a project from a client where the ability to administer a subfolder on the server-side is central (CRUD directories and files within a subfolder in the web app). I'd love to be able to do this project with SL3 and RIA services!

Is this possible at this time? If so, is there any chance someone could share some working examples on how to do this with SL3 and RIA Services?

Thank you so much for your time and sharing your knowledge :-)

Thank you Martin for clarification.

Hi, Sanjay!

Yes, there is a specific reason for this and is related to the DomainDataSource and the paging. The DomainDataSource controls has a LoadSize property, which determines the count of the items loaded. When not set and there is a DataPager control bound to the DomainDataSource, it loads a number of items equal to the page size.

The next article of the series will be focused on the DomainDataSource and we'll take a much closer look at this feature of the control. :)

Thanks Martin for the article. It will be a great start to work on SL3 building LOB apps.I have a question, when nagiating the records using the paging it is taking more time even though the page is already loaded. I went from page 1 to 2 and then when I click back it takes the same time. Any specific reason? Is it the default behavior?
