SL 4.0 commanding provides easy and flexible code-less development mechanism. Command is a class that supports the ICommand interface and lets you data bind specific operations in your application. In Silverlight 4, there is a new pair of properties added to the ButtonBase and Hyperlink classes named Command and CommandParameter that lets you do so. I started working on it and in this article; I will be discussing it with you.

Silverlight 4 is now supporting the commanding that we’ve come to love from WPF. Commanding was a foundational feature for MVVM. It’s what enabled us to bind to methods on our view models.

John Papa shares a very simple technique to implement commanding in Silverlight 4.

Implementing ICommand in your Silverlight 4 project only requires a few steps. I have had a dozens of questions about this lately so I decided to share a very simple technique to implement commanding in Silverlight 4.

Introduction

Last month I wrote about how we could take some of the new features of Silverlight 4, Webcam control,  and create a simple application that lets you store captured webcam photos to isolated storage and your file system.

In this article we will take this proof of concept and demonstrate how through the use of commanding and binding we can virtually eliminate all code behind and implement to a strong MVVM architectural pattern.

Getting Started

I think few would argue with the value of a strong separation of concerns within the design of an application.

In this post, Fredrik Normén shows how to reduce the number of ICommand classes.

In my previous post about using Silverlight 4 Commanding, I got a question why I didn’t use delegates etc instead of creating a lot of ICommand classes. In this post I’m going to show how you can reduce the number of ICommand classes.

Whenever a new version of Silverlight is released, I start examining its features from two perspectives: how would my current (and planned) LOB applications benefit from using these new features, and what cool new things can I build to entertain my children.

This article will guide you through the process of creating a doodling application (you know, for kids ;)), while covering some of the most visible (or not) new features, coming with Silverlight 4. But this is not just about new features, it’s about how they are prepared and served.
