    This is the fourth post in my Silverlight Reference Architecture series, so after having covered querying, commanding and the domain model, it is time for discussing some of the Silverlight application details.

    In this article, Michael Washington explains programmatically selecting a Silverlight Tree View Control node using View Model (MVVM).

    When using the Silverlight Tree View Control, you will discover that it is not easy to expand a Tree Node programmatically without using code behind. This article shows how to do that using a Behavior.

  • VMCollectionWrapper - Synchronize a Model collection with a ViewModel collection

    In this article, Brett Balmer discusses VMCollectionWrapper - a class that synchronizes ViewModel collection changes to Model collection changes.

    Source: The <silver/> method

    There has been a lot of debate around what to do with collections of Model objects live under a ViewModel. Consider the situation where a Person has a collection of Nicknames and you have created a PersonViewModel. The debate centers around whether you should expose the Nicknames to binding directly, or if you should create a collection of NicknameViewModels to which binding should occur.

  • Architecting WP7 - Part 3

    In part three of Architecting Windows Phone 7 applications, Shawn Wildermuth wants to talk about locating the View Model.

    The phone is a small platform (no pun intended) so your Silverlight apps may be smaller than you might imagine. In addition, you are tied to the page navigation story (a good thing IMHO) so you may want to look at handling view-models in a different way.

  • Expression Blendable Silverlight View Model Communication

    Michael Washington explains how to easily implement two-way communication between Master and Child View Models that works with Blend.

    Source: The Code Project

    In the Silverlight Debate Forum project, the developers asked for two way communication, and they wanted it to be 'blendable', meaning, they could use Microsoft Expression Blend, to easily select ICommands and set properties in any View Model control, from any View Model control.

    The end result, allows you to call any Master or Child control, from any Master or Child control.

  • Patterns of Windows Phone Architecture Part III

    In part 3 of the "Patterns of Windows Phone Architecture" series James Ashley is talking about the Satellite ViewModel.

    The Anchor ViewModel pattern described in part 2 of this series is especially well adapted to Hub style layouts where related user controls are organized under a common parent. For instance, a Pivot Control can have a MainViewModel object assigned to its DataContext. If the MainViewModel class has properties with additional ViewModels, for example DetailsName, DetailsAddress, and so on, each of these properties can be used as the DataContexts of the Pivot Items contained in it.

  • Silverlight 4 Databound CheckBoxList and RadioButtonList Controls

    In this post, Benjamin Day demonstrates how to databind RadioButtons or Checkbox controls to a ViewModel in Silverlight 4. 

    Last week I needed a CheckBoxList control and a RadioButtonList control for Silverlight 4.  I was surprised that they weren’t already part of the standard controls or the Silverlight Control Toolkit.

  • Basic Silverlight View Model Validation

    Tags: Validation , ViewModels , Michael Washington
    In this post, Michael Washington discusses one of the most basic types of Silverlight Validation - validating that the data entered matches the underlying type.

    We will start of with the Creating Multiple Dynamic View Models using the Tab Control project. We add a DueDate field to the Tasks table that is nullable. We will alter the View so that it has a “Due Date” field and permits these operations:

    • Indicates when a valid date is not entered
    • Allows you to not enter a date at all
  • Silverlight View Model Communication

    0 comments  /  posted by  Silverlight Show  on  Jul 06, 2010 (4 months ago)
    Michael Washington has an example of Silverlight View Model communication between Master and Child View Models.

    With using "View Model Style" programming it may be a little confusing as to how you can communicate between View Models. There are various methods available, but this article explores what I hope to be an easy simple method.

    View Model Style allows a programmer to create an application that has absolutely no UI (user interface). The programmer only creates a View Model and a Model. A designer with no programming ability at all, is then able to start with a blank page and completely create the View (UI) in Microsoft Expression Blend 4 (or higher).

  • RIATasks: A Simple Silverlight CRUD Example (using View Model and Rx Extensions)

    An example of a Silverlight Application that implements Create, Read, Update, and Delete using web services and RX Extensions.

    The reason for this tutorial, is that I have noticed my friends are getting stuck when trying to learn Silverlight. They spend a lot of time "learning about Silverlight" but have a hard time actually getting started.

    I also wanted to show them how to use View Model Style programming because I believe that using View Model, you will write LESS CODE (you probably didn't expect that one!). Don't believe me? Let me show you...
