Wpf binding not updating property
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.

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.

The project will add necessary libraries and the ‘View Model’ folder with the following two classes: - Main View - This class is inherited from View Model Base class and it provides access to Raised Property Changed method for notifiable properties.
