Don't work in Chrome, don't work in IE 7, but works fine in Firefox.

Silverlight 3? Maybe they should stop producing this bullshit already. Totally useless. In real world no one uses that crap!

Excellent demo! Thanks Brad! Great work! I also liked that you actaully used IE in you demo. Many MS presenters I have seen use firefox which is quite ironic. :) I can't wait to explore SL3/RIA more. few questions ... 1. IS it possible to see dirty flags in master datagrid? I would then know how many records I have changed. Same with the new Employee record or delete employee record. (hopefully different kind of flag for these two). Is that dirty bit display cutomizable? 2. What is the best suggestion to arrange folders/projects in the Silverlight solution? especially folder structure in web project when the project is big. 3. I would also like to see examples of(MVP/MVVM) patterns or any recommended pattern for Silverlight and how it works wih SL 3/RIA. 4. Conflict resolution - any example/demo? Sorry for the long reply, I am just too excited about the product and where it is going. Thanks!

Thank you for creating and adding so much value to Silverlight making our personal investment in learning WPF\SL worth of gold!

Any ideas on when Microsoft is going to ship .NET RIA Services RTM or Beta? I have already prepared a worthy niche for it in my projects.

I'm not a big fan of Virtual Machine-based RIA tecnologies (Silverlight, Flash/Flex, JavaFX, etc), but this started to look interesting. Finally getting beyond the media player functionality. Thanks for the demos.

Nanny says "Silverlight 3? Maybe they should stop producing this bullshit already. Totally useless. In real world no one uses that crap!" Sorry Nanny, if you want to compare "real world" apps that I've seen (the horror, the horror), Silverlight 3 is a pretty viable framework. We have several clients on board, in design phase and SL3 is our target tech. We were looking at Adobe AIR, but SL3 out of browser lets us leverage the client's teams and our firms .NET training (which between development and maintenance is the real story and the real world).

I think nanny is pretty confused about what SL3 is, RIA services will be a reborn of silverlight and by far will more than ever be the option to develop RIA applications for the web, at least a platform that has it all

Is the code for this available for download, it really should be clearly linked from here

A walkthrough and the source code is available at this address: http://blogs.msdn.com/brada/archive/2009/03/17/mix09-building-amazing-business-applications-with-silverlight-3.aspx The blog address is mention at the very end of the video, then you've got to hunt for it, a clear and direct link on this page would have been useful to have to hand while watching the video

Were there breaking changes in the May preview that would affect someone working based on this video? For instance in the video "using MyApp.Web;" is where I am stuck.

Rob — Mon, 20 Jul 2009 02:39:26 GMT

Hello. Great demo, and I love Silverlight 3. I have an existing application with a silverlight (was version 2) gui connecting to WCF services. I was wondering, is there any way to leverage that great filtering/sorting technology without throwing away my entire middle tier and rewriting to use this RIA context-service stuff? Many thanks, Rob

Two questions: 1. At 18 minutes into the video, Brad auto-generates the NorthwindDomainService code, and at 31 minutes, he adds hand-scripted code into the generated file. This is bad. Could this have been done using partial classes? 2. Could the data validation have been done by making the domain class implement IDataErrorInfo rather than using DataAnnotation attributes?

Rashad Rivera — Tue, 11 Aug 2009 19:51:48 GMT

I am trying to walk through the demo with the released version of SL3 and RIA, but I ran into some snags. One, in the video, you call the LoadEmployees() method on the context object to load date into the DataGrid (see video at 22:00), but in my application, there is not code gen LoadEmployees method. Could this be something that changed since this video was published? How does one load the data on the client side now?

RE: Building Amazing Business Centric Applications with Microsoft Silverlight 3

Bogdan — Thu, 13 Aug 2009 12:12:09 GMT

@Rashad Rivera Here's how to get the data with the latest release of RIA Services (July 2009): AdventureworksContext riaContext = new AdventureworksContext (); EntityQuery query = riaContext.GetSalariedEmployeeQuery(); LoadOperation loadOp = riaContext.Load(query); this.dataGrid1.ItemsSource = loadOp.Entities; Read an up-to-date walkthrough about this here: http://code.msdn.microsoft.com/RiaServices/Release/ProjectReleases.aspx?ReleaseId=2387

I am having problems with the DomainDataSource. When I try to use the DomainDataSource nothing is displayed in my data grid, though if I go away from the DomainDataSource and use the context to set my data grid itemsource from my xaml.vb file it seems to work fine. I would really prefer to use the DomainDataSource. Has anyone else had similiar problems and if so can you tell me how you have resolved the problem? Thanks.

RE: Building Amazing Business Centric Applications with Microsoft Silverlight 3

Rashad Rivera — Fri, 14 Aug 2009 18:21:11 GMT

Shawn, Without looking at your code (or knowing how you wired up the controls), I can only speculate as to the cuase of the issue. However, from initial experience, if you don't use the "QueryName" property on your DomainDataSource control, it won't automatically load the data. Here is a "gotcha" for you just in case, the value of the "QueryName" must the name of one of your query methods you defined on the Web side. I *think* you can declare query methods on the client-side code, but I have not researched that as of yet.

Ashish Sayal — Thu, 27 Aug 2009 02:24:41 GMT

Use this code: var ctx = new CountryDomainContext(); DomainDataSource dds=new DomainDataSource(); dds.LoadSize = 20; dds.QueryName = "GetCountryQuery"; dds.AutoLoad = true; dds.DomainContext = ctx; dds.Load(); CountryGrid.ItemsSource = ctx.Countries;

RE: Building Amazing Business Centric Applications with Microsoft Silverlight 3

Ashish Sayal — Thu, 27 Aug 2009 02:28:20 GMT

Very important: DomainDataSource in SL3 RTM version doesn;t have method named "LoadMethodName" and it is replaced by QueryName. Pls see my previous post on it. Very difficult to find info on what got changed from this demo. I request Nikhil/Brad to post changes or update the demos'.

Creating my on example based on this, it works until I try to go to page 3. The activity control shows activity to theserver, but only the first 20 records are again returned. Do I need to adjust my Entity Query to except to data page I want to return? thanks prussell

prussell — Tue, 15 Dec 2009 17:52:02 GMT

Appearantly the DomainDataSource needs to have a SortDescriptor. http://forums.silverlight.net/forums/p/150714/336262.aspx#336262 prussell
