Give permission to the users

[raghulvarma]

In my module I have different users sush as administrators, managers,users.
I have a menu items displaying the differerent links to diferent pages.
All menu Items should be displayed to the admin, some menu items should be hidden from user and some other menu items should be hidden from mangers,how should it be done?

[joedeene]

either the .visible or .enabled property in most controls, forms, menus, etc ?

the .visible property will pretend like its not even there, its not visible, the .enabled it shows it, but basically, you cant click it, or use its actions...

I am sorry that you did not understand my question, I need the menu Items to be displayed or not at runtime in accordance with the person who has logged into the page.
ie
If a person logs into the page the system has to check whether it he is admin or staff or a manager.and then has to make decision whether to enable all menu items or to hide some items if the person is not a admin
any help?

use a boolean then ? like if an admin logged in...

declare your booleans at the beginning, and once logged in, set a static(shared) boolean to true depending on the user authenticated, lets say a manager...

 
        bool adminauthenticated = false;
        bool managerauthenticated = true;
        bool userauthenticated = false;
//then code to show the page after logging in, then a simple if statement such as...
 
 if (managerauthenticated == true) 
            {
                //enable some...
            }
            else if (adminauthenticated == true)
            {
                //make visible, or enable all controls
 
            }
            else if (userauthenticated == true)
            {
//show the controls you want
            }

is this something useful ?

You can check the user by:

IPrincipal user = Page.User;
 

Then you can check that the user is in a specific group like so:

string strRoleToCheck = "Administrator"; // could be what ever group you need to give permission to.
user.IsInRole(strRoleToCheck)

I think the part that isn't being said is that you have to manually turn each and every menu option on or off. There isn't an 'automatic' way of doing it.

1. The user logs in
2. That loads their permissions from someplace. Might be database, file, registry, whatever you decide.
3. As JoeDeene suggested, hold their permissions in a series of booleans. For example "bShowConfirmDialogs", "bAllowChangeUsers", "bAllowExitApp"
4. Once logged in set all the booleans from their permissions.
5. Go to a method that turns on features and menus according to the booleans.

I usually have a series of statements like this....

closeToolStripMenuItem.Visible = bAllowExitApp;
edituserToolStripMenuItem.Visible = bAllowChangeUser;

Also, don't forget there is more than one way to do many things, like exit an application. Just because you take away the File|Exit choice there is also the big red 'X' button as well as [ALT]+[F4], and closing from the task bar. So you have to make sure you check the bAllowExitApp permission when the application is closing. If there is a way around something, some user will find it. You have to cover all the bases.
