I’ve been intending to write a sample using the ComboBox for a while. The more familiar you get with Silverlight, the more you realize the ComboBox causes all sorts of problems. I have mixed feelings about the proliferation of posts I’ve seen on this...

This is an introduction to the Authorization Sample for RIA Services . Authorization is implemented using attached properties. This means you can mark nearly everything in your xaml files with Authorization properties. In most cases, elements will be...

[This sample references out-of-date API. This newer post discusses the updates made for the V1 SP2 Preview and shows how to implement filtering.] There’ve been plenty of talk about an MVVM-friendly DomainDataSource . I’m pretty sure it means completely...

One of the most common tasks when developing a RIA Services application binding to a collection of data. There are some declarative options that include binding directly to your DomainContext or DomainDataSource . These options are great for spinning...

We worked right up to the deadline, but I’m happy to say we got a preview of RIA support for Windows Azure Table Storage into the October Toolkit release (that coincides with the SP1 Beta release ). You could integrate with table storage previously, but...

RIA Services does not support Out-Of-Browser (OOB) Forms authentication using the Client networking stack out of the box. The Client stack is often recommend for OOB scenarios as it provides a greater level of control over requests. The reason authentication...

To correspond to the new RIA Services build we’ve released at Mix, I’ve made some updates to the DomainCollectionView . I updated select API, fixed a few bugs, and updated the sample as well. If you’re not familiar with the DCV , here’s my original post...

I’ve wanted to do a follow up to my original ComboBox post for a while now. I answered a number of the questions throughout the comments, but I thought I’d gather all the answers up and add some nice code samples. Hope this helps. How do I use a ComboBox...

I need to ask a favor of all my regular readers out there (*crickets*). I often hear stories along the lines of “I use the DomainService Wizard to generate my DomainService. Then I make tiny changes to the generated code or metadata and may move it or...

There have been a lot of questions recently about how to write authorization-enabled UI in Silverlight. We’ve always floated suggestions from the RIA Services team, but never put something concrete together. I decided to take some of those ideas and run...

The attached properties described in Authorization 101 will get you going. It may even be a long time before you need more. If you find yourself chafing at the limits, though, then this section is for you. It works through some of first customization...

The Authentication support in RIA Services uses ASP.NET Membership, Roles, and Profile support by default. While this provides a lot of power, flexibility, and interoperability, it may also leave you wondering “How do I use ASP.NET Membership in Silverlight...

I’ve been excited about this CTP for quite a while now and it’s great to finally have a chance to play with it. Way back in early RIA days we had a number of conversations with the TPL (Task Parallel Library) folks to see if we could use Task<T>...

In this thrilling conclusion to my series on unit testing, I’ll show you how to use the DomainServiceTestHost to test your DomainServices. In parts one and two I showed you how to extract external dependencies using the IDomainServiceFactory and how to...

At the Silverlight Firestarter ‘10 , John Papa did a great talk on MVVM Patterns for Silverlight and WP7 that featured WCF RIA Services as the data layer. For that talk, I helped him streamline the service layer abstraction to correctly work with the...

For our WCF RIA Services V1.0 SP1 Beta release we were finally able to improve binding support for EntitySets and EntityCollections . In our V1 release, EntitySet and EntityCollection did not support adding and removing entities through the IEditableCollectionView...

My teammate, Jason Cooke, put together this great article on changing the timeout in RIA Services. Hope you find it helpful. Change Timeouts for WCF RIA Services WCF RIA Services specifies default timeouts for its endpoints, so you can be sure that all...

In Authorization Sample 301 I explained the ins-and-outs of the authorization sample and offered a few hints as to how it could be used. In this post, I will show a specific example where I show how to extend the authorization library to support read...

The question I’ve been fielding most lately is how to write a custom CollectionViewLoader . Once you see it done, it’s a pretty simple task. Without an example it’s hard to know where to start. In a previous post, I discussed how the view, loader, and...

The other day someone asked me how to get a ComboBox working with enums and validation. It turned out to be more tricky than I had anticipated ( there’s a common theme here… ) so I figured I’d put together a quick post on it. Stumbling Points This section...

For this post, I’ll assume you read my intro to Windows Azure Table Storage . If not, take a second to read it. This time around I’m skipping past the contextualizing. In my first entry, I showed how to get a simple entity all the way from Table Storage...

In Authorization Sample 201 , I touched on some of the extensibility options for custom authorization. These include applying custom rules or setting target properties for custom bindings in xaml. I avoided the bigger picture, however, by neglecting to...

Ever since Deepesh posted this awesome article a couple months back, we’ve wanted to give you a template for creating a Silverlight Business Application that looks the Zune client. We started with the Cosmopolitan Theme , applied the tweaks he listed...

Earlier this week it was announced that Windows Azure now supports .NET 4. I figured a few of you would want to know how you could write a RIA Services application that ran on the cloud, so I thought I’d put something simple together to get you started...

The second most requested feature on our WCF RIA Services Wish List is an MVVM-friendly DomainDataSource . The neat part about this request is that it means many different things to many different people. The challenge in addressing it is to figure out...
