I have added another article to Code Project: A WPF Spinner Custom Control which describes the process of creating a simple spinner control in WPF using the framework.

This follows up from my previous post where I created a simple UserControl to select a TimeSpan. In the absence of a spinner control I used sliders instead. Writing a spinner control has been an educational experience: whilst I have previously written controls, writing a new one from scratch and adhering to the various framework guidelines and conventions (to a degree) meant that I had to read through much more of the MSDN documentation than I would previously have taken a look at.

What makes the article a little different to some of the others out there, is that I try and mention each part of a custom control: the code, the generic theme, and then applying a custom theme to it.
