Summary
Silverlight 4 now came up with the support of Command Binding. Using Command Binding you can easily develop your Silverlight MVVM (Model-View-ViewModel) applications where your view will not know about the data i.e. a full separation of the view from the model. In this article I will describe you how to implement the command binding to load some informations & display it to the UI.
Excerpt
"In earlier version of Silverlight, if you want to load something on the click of a button, you have to register the event in your view and then you had to call the appropriate method to load data. Lets say, as an example I want to load the customer information of my grocery shop when I click on a specific button. How will you implement this in Silverlight? The answer is simple. I will register a Click event of the button and then I will call the CustomerProvider to load the customer information in my view. It’s simple enough but do you agree that this scatters your view with the functionality to load the informations? Yup, this backend related calls are tightly coupled with your view. They know each other and if I want to give the same call from a different button, I have to register the click event for that button and then have to give a call. It looks a bit ugly in normal scenarios."
