Introduction

WPF provides several ways to customize elements, from simple property changes, through content changes of content controls with data templates, up to using an entirely new control template.

All these options change the way an element appears, but its functionality is unchanged. If a new functionality is desired, a custom element is needed.

In this chapter, we'll take a look at a number of ways of creating custom elements and controls. Some are simple, but lack flexibility, while others are extremely flexible, but require more work.
