title: WPF schedule control
body: <p>I'm looking for a very simple schedule control for WPF.
  What I need is something like daypilot or the Outlook scheduler but with minimal functionality.
  I simply want to show a day separated in 24 interval (one for each hour). Inside these 24 hours, the user has to define events/task, non-overlapping each other. That's for theory.
  Practically, I want to write a control where the user can define inside a day and for each day a week, how much a kWh of electricity costs.</p>
  
  <p>I found a lot of samples, but most of them are very complex, or simply doesn't work!</p>
