Xceed SmartUI version 2.0 only has one new property, although it is a very powerful one:   When you set the XP property to True, your existing SmartUI application will instantly have the same look & feel as Microsoft Office XP.

 

SmartUI.XP = False

SmartUI.XP = True

You can use both version 1.x and 2.0 of SmartUI side by side because they use different GUIDs.   Converting your project to SmartUI 2.0 is easy using the Upgrade Wizard.
