Implementing a Windows Forms owner-drawn trackbar (slider) control in C#.

Sample Image - ColorSlider.gif

Introduction

This article presents owner-drawn trackbar control. Component is written entirely from scratch. All painting events are done by code. It’s got cool, modern look. The best thing is, however, the capability of changing slider’s thumb shape. It is done simply by providing appropriate graphics path.

Background (optional)

I always wanted to have cool slider for my audio player application. The best I could find here was Guinness4Strength's article. Unfortunately, I didn’t find it pretty enough, so I decided to write my own trackbar. Hopefully you like it.
