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.You can read more about the different binding modes here.

At first i like to thank you for this wonderful job.
The main difference is, that the value of a normal .
NET property is read directly from a private member in your class, whereas the value of a Dependency Property is resolved dynamically when calling the method that is inherited from Dependency Object. This baseclass defines a key, value dictionary that contains local values of dependency properties.
If no value is found it takes the default value defined in the property metadata. This wrapper does nothing else than internally getting and setting the value by using the Get Value() and Set Value() Methods inherited from Dependency Object and passing the Dependency Property as key.
This sequence is a bit simplified, but it shows the main concept. Important: Do not add any logic to these properties, because they are only called when you set the property from code.
