    In this post, Jeff Handley examines how attributes declared on your model are propagated to the client.

    Source: Jeff Handley's Blog

    Since the beginning of the RIA Services project, a primary tenet was to propagate validation rules defined on the server up to the client, integrating the validation directly into the Silverlight UI. This came to fruition with RIA Services v1.0 and you can in fact apply an attribute to your model on the server and automatically get instant client-side validation of data entry on even the simplest of Textbox controls. In fact, some validation rules are inferred from your data model directly. This is a feat that many other frameworks have attempted to accomplish, but I believe RIA Services has one of the most successful implementations of the concept.

  • RIA Services Validation: Custom Validation Methods and Custom Reusable Validators

    Jeff Handley has two more posts from his series on RIA Services Validation:
    • RIA Services Validation: Custom Validation Methods
    • RIA Services Validation: Custom Reusable Validators 

      We just covered Custom Validation Methods, where we learned how to use CustomValidationAttribute to invoke a static (VB: Shared) method to perform validation. Let’s talk about an alternate approach to custom validation though: creating custom, reusable validators by deriving from ValidationAttribute. While it’s true that the custom validation methods used by [CustomValidation] could certainly be reusable, I tend to think of that approach as a light-weight way to call specific business logic routines for validation. The approach we’re about to see is what I use when I’m creating an inventory of validators to be reused throughout my project(s).

    In this post, Jeff Handley talks about RIA Services Validation and demonstrates how the standard validators work.

    Source: Jeff Handley's Blog

    RIA Services offers powerful features for flowing validation from your entity model all the way up to the Silverlight UI. In fact, flowing your validation rules from the server into your form controls was one of the primary tenets of RIA Services V1, and our team did the work of getting validation integrated deeply into Silverlight, long before RIA Services was released. In this post we’ll take a look at the standard validators that are offered.

    Vincent Leung offers you to download the refreshed Silverlight 4 themes (inlcuding RIA Services templates).

    Source: Vincent Leung .NET Tech Clips

    At the link above you’ll find 3 files to download:

    • README_FIRST.txt – please read this but basically I’m writing the same thing here.
    • SL4Themes-templates.zip – this includes a folder for Expression Blend and Visual Studio templates. The VS folder also has a sub-folder for the RIA Services templates.
    • SL4Themes-rawassets.zip – this is another (optional) zip that includes the resource dictionaries for each template on their own without any Silverlight project.

    Introduction

    In Part 5 I discussed metadata classes and shared code, and one of the example uses of metadata classes I showed was using a [Required] validation attribute to cause some validation on both the client and server side.

    Introduction

    The Model-View-ViewModel pattern (MVVM) is a very popular approach for building more loosely coupled Silverlight and WPF applications.

    In this post, Sergey Barskiy discusses UI testing and test automation with StatLight framework.

    In my last post I am going to cover the last two topics I set out to address.  The first topic is UI testing.  What unit test frameworks lack sometime is the actually UI testing.  What I mean by that is for example, click on a button, then see what happens.  In case of Silverlight, Silverlight framework itself has a number of helper classes to help us achieve this goal.  For example, ButtonAutomationPeer class allows us to drive button actions from within unit tests.  Also, Microsoft Silverlight unit testing framework allows developers to insert UI components onto unit testing surface.
