Thank you for this link but this is not quite what I am looking for. It is suggesting the use of sitemap and bind it to the menu control. I am looking for something that involves database. For example let's assume that there is a master table in the database called roles_mst which has the following data ---

role_name    role_id

------------------------------

admin            1

faculty            2

student           3

This means that users registered with the application can belong to any one of these three roles. For eg let there be a table called users_info containing data like --

user_id              user_fname               user_username                 user_pwd                  user_role.............................................

------------------------------------------------------------------------------------------------------------------------------------------------------

1                      John                          john4ever                          xyz                              2

2                      Lucy                          lucy                                   lucy2121                      1

3                      Max                         Maxlove                               qweasd007                  3

and so on

Now when the user logs in by providing username and password the application will check his role and accordingly present him with the subsequent menu, which will be different for all three roles. How to do this?  

Thanks.
