I have added yet another CodeProject article entitled A WPF Short TimeSpan Custom Control that builds up on my previous article that creates a simple spinner control.

The introduction to the article is here, but go to the CodeProject web site for the full article:

Introduction

In my previous two articles, I first described a simple short TimeSpan UserControl that used sliders to pick the hours, minutes, and seconds of a TimeSpan. In my second article I described a custom spinner control that could be used to replace the sliders.

In this third article, I will update the TimeSpan control to use the SpinnerControl, and make the TimeSpan control a custom control, rather than a UserControl (in particular so that we can apply custom themes to it). I refer to this as a ShortTimeSpanControl as it only represents a positive TimeSpan from 00:00:00 to 23:59:59. A full TimeSpan is described here:

A TimeSpan value can be represented as [-]d.hh:mm:ss.ff, where the optional minus sign indicates a negative time interval, the d component is days, hh is hours as measured on a 24-hour clock, mm is minutes, ss is seconds, and ff is fractions of a second. That is, a time interval consists of a positive or negative number of days without a time of day, or a number of days with a time of day, or only a time of day.

With the generic theme supplied, this is a selection control, where the user can choose a TimeSpan. As it is a custom control, you can apply any custom theme you like, and, perhaps, just make it a read-only control (interactively, that is), that updates its Value via data-binding.
