Wpf dependency property binding not updating

In WPF applications, dependency property is a specific type of property which extends the CLR property. It takes the advantage of specific functionalities available in the WPF property system.

That confirmed my belief that WPF does not forgive any single developer’s mistake.

I have am writing a WPF application, and I have a textbox for the user to enter a frames per second value for video playback.

The value of this textbox is bound to a dependency property in the code behind (trying to follow MVVM like a good designer).

The dependency properties value is changed correctly by the slider, but the textboxes text never updates, unless, of course, i do it manualy using Get Binding Expression(..).

Update Target() which is what I have implemented pending a better solution.
