What is new in RadColorPicker for ASP.NET AJAX

Localization for the slider mode UI strings.
CDN support --Starting with the Q3 Service Pack 1 release you will be able to load the control scripts and skins from the Telerik CDN.
New Windows7 skin

New property called Localization which provides the ability to localize the strings in the user interface. The Localization property exposes the following properties:
PickColorText
CurrentColorText
NoColorText
WebPaletteTabText
RGBSlidersTabText
HSBTabText
ApplyButtonText
New server-side property:
OnClientPopUpShow – gets/sets a value indicating the client-side event handler that is called when the pop-up palette of the RadColorPicker (in case ShowIcon=true) shows.
New in client-side API:
add_popUpShow
remove_popUpShow
The default value of the Preset property is set to Default
Added a new property OnClientColorPreview to replace OnClientColorSelecting (which is now obsolete)

New property - KeepInScreenBounds. When set to “false”, the RadColorPicker will not reposition its palette (ShowIcon=true) so that it opens in the visible viewport when necessary. Its default value is “true”.

Added one new property to the RadColorPicker - PaletteModes.
Changed the HTML of the RadColorPicker: create a TabStrip when PaletteModes=All; changed the position and look of the Preview element; changed the position and look of the NoColor button
Total redesign of the skins, which aims for a uniformity of the appearance of all controls in the suite in the cases they are used to build RIAs
Refactoring of the CSS code to achieve better understanding, easier maintenance and handle problems with global styles
Changes to the css classes, so now all controls for ASP.NET AJAX comply with a common naming convention
