New Controls
ColorBox
We could not leave GridViewColorColumn without introducing the respective control. RadColorBox will allow the end-user to pick a color of his choice via the RadColorDialog. Even if the selected color is a custom color, rather than a well-known color, it will be displayed in a easy-to-understand manner thanks to the color square at the left side of the editor.
BrowseEditor
The same here. GridViewBrowseColumn lead to the creation of the RadBrowseEditor. As the name of the control suggests, it is composed of a textbox and a button, and it allows users to select a file or a directory from the file system using OpenFileDialog, FolderBrowserDialog or directly to type the full path to the file.

Panorama
We highly improved RadPanorama design-time support by introducing a Live Tile Editor. This editor will allow you to create tiles that will really vivify you application thanks to the number of animation options available.
Scheduler
RadScheduler got improvements mainly regarding its built-in multi-touch support. Now you can switch between views or navigate in a view with a simple gesture. ((Read More)) http://blogs.telerik.com/winformsteam/posts/11-12-07/the-ultimate-scheduler-touch-experience-for-winforms.aspx

GridView
Q3 2011 brings Excel-like filtering enhancements in RadGridView: Calendar filter popup for date columns, Simple list filter popup, Grouped Date Filter Popup, and Custom Filter Popup. Read more.
Four new highly requested columns allow for representing the underlying data in the appropriate manner. In addition, these columns come with their own editors which allows the end-user edit the values represented in these columns. The columns are: Browser, Calculator, Hyperlink and Color columns. The Browser editor allows the end user to browse using both a textbox and a button, while the Calculator editor allows the user to submit a value resulting from a mathematical calculation. The Hyperlink column represents the given data as a link and when the user clicks that link, he/she is transferred to a specified web page. The Color column employs our RadColorDialog and allows you to pick a color and then display it in RadGridView.

Full Multi-Touch Support
We have wrapped the native touch API of Windows 7 and Windows 8 and exposed a powerful API that will allow you to enhance your Windows Forms application in a way you have never thought of before. To put it simple, you will be notified when pan, zooming and rotating touch operations occur to your RadControls, so that you can handle these notifications and process them accordingly.
