Guidelines for Designing Stylable Controls

Guidelines for Designing Stylable Controls: "Guidelines for Designing Stylable Controls

This document summarizes a set of best practices to consider when designing a control which you intend to be easily stylable and templatable. We came to this set of best practices through a lot of trial and error while working on the theme control styles for the built-in WPF control set. We learned that successful styling is as much a function of a well-designed object model as it is of the style itself. The intended audience for this document is the control author, not the style author.

This topic contains the following sections.

Control Templates
*

Data Templates
