Hey I found nice solution for slider on stackoverflow: WPF: Slider with an event that triggers after a user drags
The problem is I don't understand why you can use Thumb.DragStarted or Thumb.DragEntered inside a Slider (any control) that has no co-relation with each other?
Is that because Thumb.DragStarted event is implemented that way that it doesn't matter for it what will invoke that function?
