This is the sample corresponding to the CustomControl tutorial.

In contrast with UserControls, that are created by composition of controls, a CustomControl extends an existing control. CustomControls can be styled and it is usually the best approach to build a control library.

Creating a CustomControl is quite simple but the challenge is to do it the right way. So before you start creating a control try to answer the following questions:

• What problem should my control solve?
• Who will use this control? In which context and environment?
• Can I extend or compose existing controls? Have you look at existing controls?
• Should it be possible to style or template my control?
• Is it used in a single project, or part of a reusable library?

This tutorial gives you a step by step walktrough on how to create a custom control to represent Date and Time.
