As Miro mentioned in his
 last post, with the upcoming 2011 Q1 Beta, we will release a new and improved version of RadSlider. A lot new features are being added and many of the existing hot spots were addressed along the way. One of them - the performance hit when RadSlider has to re-render its ticks. I took the liberty to compare the impact of RadSlider on an application before and after we made the improvements.  
Scenario: Every second, for 60 seconds, generate a new ViewModel and set it as DataContext to RadSlider.  
Goal: See how many times the LayoutUpdated event will be fired. 
Additional Info: The ViewModel has 2 properties (Value and Maximum) which are bound to RadSlider's Value and Maximum. 
Anyway, instead of telling you how great the new Slider is, why don't I show you instead. 
 
 Note: The new Slider is represented in the upper window.
