Performance Improvements in RadSlider
As Miro mentioned in his last post, with the upcoming 2011 Q1 Beta, we will release a new and improved version of RadSlider.

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...

I’m happy to announce that with the Q1 2011 SP1 release RadTileView will have yet another new and amazing feature – selection. This will allow you to mark, group or highlight your TileViewItems with a single click. The TileView selection supports three modes: Single – this is the default selection mode and it is the simplest one as well. In this mode you select/deselect an item by a single left mouse button click and you can’t have more that one selected item. Multiple – this is similar to the Single mode, the only difference is that you can select more that one item. Extended – this...
