I'm in need of a piano roll control with drag&drop editing functionality that is based on WPF.
I saw at the roadmap of NAudio that this is already planed and found the blog post about the WPF based piano roll control (http://mark-dot-net.blogspot.com/2008/06/creating-piano-roll-in-wpf-part-2.html).
Is such a control still planed? If not, how would you guy build such a control (e.g. should one use bindings? how should drag&drop be handled? - I'm a total newbie at WPF)?
