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.

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...

We are happy to announce the immediate availability of the first service pack for our RadControls for Windows Phone 7 tools. This is mainly a maintenance release with lots of bug fixes (more than 30), performance improvements and several small new features over the existing controls.

Our toolkit is now even more stable and we are aiming high to make it as bug free as possible. A complete list...
