Wpf binding not updating property - dating with a learning disability

HTML defines the content structure, CSS defines content presentation and Java Script defines how the content interacts and behaves with the user.

Note that the information in this post may also be applied to other controls implementing Items Control. Along the way, I came across a situation where I needed to do some different kinds of binding using Combo Boxes.

Now that we’ve got a decent understanding of the common binding properties of a Selector control (I hope! Given the following classes (only class signatures; the full sample project including source code is attached to this post): Note the use of “Mode=One Way” in my Items Source bindings.

This indicates to the binding that we’re only going to be updating the binding target (the Combo Box’s Items collection in this case).

For those interested, there’s a good article by Martin Fowler which explains the differences in these patterns over here.

XAML enables So C in WPF, Silverlight, Windows Phone, and Windows 8 apps by separating the GUI of the application from the programming logic (coded in C #or VB. Model-View-View Model (MVVM) is a design pattern that addresses So C by allowing separation of your Business logic from the View (UI), which ultimately makes it easier to write unit tests and enables parallel development and design.

We will be exploring how to implement MVVM in WPF applications using the MVVM Light Toolkit by Laurent Bugnion.

The main purpose of the MVVM Light toolkit is to accelerate the creation and development of MVVM applications in WPF, Silverlight, Windows Store (RT) and for Windows Phone The steps explained in this article are targeted specifically towards those who want to start with MVVM development and require a readymade toolkit for developing their WPF applications.This ultimately reduces duplicate code and keeps the modules decoupled from each other, making our application maintainable and manageable.As a very basic example of So C, think about HTML, CSS and Java Script, where all these technologies have a well-defined purpose.It leverages the rich data binding capabilities of the XAML platform to expose the view model to the UI through the view's Data Context property.The business layer is also termed as Model whereas the View Model layer is responsible for exposing data objects from model to the UI using Data Binding.The View Model contains the View display logic where actions on UI can be handled using Commands properties declared in View Model.
