Question

I've got the following problem,
My application has a lot of (inheritance)forms, and to navigate those forms, i use one main form with a menustrip, that contains al the links.

And ofcourse this pricilpe principle works fine as long i don't mess with it.

But now the following problem arises, i need to make "users" in my program, that can log in etc.
And of course every "type" of user has rights, to what froms they have exces etc.

But how can i change the menustrip in the "mainform", to reflect te forms that the current user has acces to?

With kind regards,

a troubled guy

(and i know i can make multiple menustrips, and hide the ones not in use, but that, of course, won't do, becouse of the sheer ammount of rights)

instead of multiple menu strips, have multiple validation methods which disable or hide menu elements. Just a suggestion. I am not sure about the complexity of your design

Yes maybe possible but what if other (existing?) code disables/enables the MenuItems for some logical reason, this can be quite messy (see my other comment)

Agreed. Alternatively if those menus are organized/ grouped well then implementing authorization would be easier. May be Original Griff's answer helps if the children from a top menu has different access privileges

I solved a similar problem with a special MenuItem implementation. I just added an Authorization property to the MenuItem to control the enabled/visual states (independend from the logical states, don't make this mistake!). Then I just applied the current authorization information to all controls (kind of recursive). Make it an interface and implement it for all controls you want to protect with rights.

Each menu strip item list can be changed when the user goes to open it: If you handle the ToolStripDropDownItem.DropDownOpening[^] event then you can set the rights dynamically when the user goes to access them. Then just disable or hide the inappropriate main menu list items.

Or add/remove -- big deal. A 5, anyway.
