Abstract: The MVVM Light toolkit provides a lot of boiler plate code to implement Model-View-View Model based applications quickly and gives the user the freedom to customize and design the application.This article shows how to get started with MVVM development for WPF applications.For the Selected Item and Selected Value bindings, I do not set a mode – this is because “Mode=Two Way” is the default.Two Way means that we want to update the property on the View Model when the selection changes, and if the property on the View Model changes we want to update the Selected Item/Selected Value on the Combo Box. I've been intrigued by computers since I was 12, staying in at recess to code QBASIC on the old Apple II.

Some examples of where this exist are: in the binding above - that's not going to work when we have a dynamic model.It took a lot of experimentation to make this happen, but the result isn't much more complicated.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.
Also, it can be difficult in WPF to know exactly when the system is finished with an object.
Separation of Concerns (decoupling) or So C is a principle that promotes best practices for software architecture.
A ‘concern’ can be considered as an aspect of software functionality.
A few weeks ago, a friend convinved me to start looking into WPF, XAML and the MVVM pattern. NET Web Forms & MVC2 applications and core system design/development, I haven’t had any exposure to these new(er) technologies, and I thought it might be fun to see what all of the fuss is about. I am using terms in this post in a way which assumes that you are using the MVVM pattern.
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.
HTML defines the content structure, CSS defines content presentation and Java Script defines how the content interacts and behaves with the user.
