It doesn't appear that there will be a color picker control in the upcoming release of Silverlight. Of course, this is just a beta, so things may change. Either way, I've developed a simple color picker for use in your Silverlight applications. My ultimate goal is to make HTML hex color code color selection easier in ASP.NET applications.
Sure, there are various color pickers available for just about every platform, but you really would appreciate how little code it took to get this working. This is really a testament to the excellent architecture of the WPF platform. Each of the artifacts in the screenshot below were created in XAML.
Over the next few days, I will publish a series of posts that describe in more detail the steps taken to build this control. I still have a little clean-up and refactoring to do, but I've already made the first drop of code available. Just follow the link below. Enjoy!
