I am happy to inform you that RadRibbonBar
control will be improved and polished for Q3 2009 release of RadControls for WinForms.
Among all other stuff, we have introduced shadow effect under the tabs, separators between the items in a horizontal Button Group (just like in Microsoft Office 2007 Ribbon Bar) and also an improved, and polished shape for the Ribbon Tabs.
Q3 2009 release is scheduled for this fall so you can download and check out what we have to offer. Thanks for your time.
