custom menus based on roles in a pivot page application

There is a menu that has all the options. But that needs to be customised based on the role of the use. Like: Student will have access only to the student related stuff Prof will have access to stuff related to him Student + Prof will have access to both of them put together.

Is there some way like I can hide a specific grid item and display the rest of them in windows pho开发者_开发技巧ne 7 pivot pages.

In Silverlight, you can hide elements (such as the contents fo a grid) by setting Visibility to Collapsed.
