I am new to WPF, The scenerio is that i am Developing the application in WPF and i have made the menu.XML file which is a datasource for Ribbon Control. Now i want to hide/Disbale the menu on the basis of user role, User role is defined in Dataabse, Lets if user is Manager then he will only see Requests Tab and similarly if admin has logged in then he might only be able to see requests tab and Admin Tab also.
