I've an N-Tier application using Silverlight for the client. The customer as one particular request - I thought was more than reasonable: all actions – including menu navigation – has to be available through keyboard.
When I tried Silverlight 4 I was surprised not to find any menu control so I downloaded several open source and commercial menu controls. I was very disappointed, after having searched for a couple of hours I didn’t manage to find any control that provide a decent keyboard support. Most controls provide no support or some basic support but not one control enabled to gain focus on the first item through the keyboard. You are able to use the keyboard (arrow keys) but you need first to select the control with the mouse! Not one control provided support for Keyboard shortcuts.

Does anyone know of any Silverlight control providing descent support?
