Can someone please give me an example in C# that creates a menu whose definition (captions, submenus, actions, etc.) is stored in a table?

I have a SYSMENU table with a column, OBJCODE, that specifies if the given row is a menu/submenu or an action to be carried out in the menu item's click method. I'd like to build the menu which may be different based on a user's access rights and roles. In my attempt, I didn't get very far being very new to C#. I created a dataset with all the rows from SYSMENU and then, for each DataRow, I use a switch to determine what type of menuitem I want to create - that's as far as I got. I don't know how to define a variable number of menu items nor do I know how to add a variable menu range for submenus nor define a new click method "on the fly" for menu items that need to perform an action.

Any help is appreciated! Thanks,
Al
