Hello Hvduc,
With the Q2 official release we added a new implementation of the ribbon control in our suite of controls. The new
RadRibbonView control implementation is in the
Telerik.Windows.Controls.RibbonVIew.dll. However, since the
RadRibbonBar and
RadRibbonView controls share the same API, the same classes are defined in the
Telerik.Windows.Controls.RibbonVIew.dll and the
Telerik.Windows.Controls.RibbonBar.dll.
This is why I'd suggest you adding a reference to only one of those assemblies in your solution based on the controls you're using. You can read more information about the differences between the
RadRibbonView and
RadRibbonBar controls
here.
Best wishes,
Tina Stancheva
