Build Error on referencing new GridView dll

[AT]

Hi,

I downloaded the latest version of Telerik WPF demo and was trying the Dlls in one of my project. The project already refers to old Telerik dlls. Wanted to replace it with a new ones. Here is the exception I'm getting on referencing the GridView..

Error 36 CA0001 : Could not find type 'Telerik.Windows.Data.IDisplayProvider' in assembly 'Telerik.Windows.Controls.GridView, Version=2011.2.712.35, Culture=neutral, PublicKeyToken=5803cfa389c90ce7'.  

Any idea what dll reference Im missing here? Following are the dlls I added in the project:
Telerik.Windows.Controls
Telerik.Windows.Controls.Docking
Telerik.Windows.Controls.GridView
Telerik.Windows.Controls.Input
Telerik.Windows.Controls.Navigation
Telerik.Windows.Data
