ABP Add dynamic Menu

The menudefinition in the ABP encapsulates the properties of the main menu on the navigation bar, and Menuitemdefinition encapsulates the properties of the submenu, which can refer to other submenus to form a menu tree.

The Menudefinitio members are as follows:

 Public ObjectCustomData {Get;Set; }//Custom Data        　　　　  PublicIlocalizablestring DisplayName {Get;Set; }//represents a localized string        　　　　  PublicIlist<menuitemdefinition> Items {Get;Set; }//sub-level menu collection        　　　　  Public stringName {Get; }//Menu Name 　　　　  PublicMenudefinition AddItem (menuitemdefinition menuItem);//submenu Add Method

The menuitemdefinition members are as follows:

 Public ObjectCustomData {Get;Set; }//Custom Data                PublicIlocalizablestring DisplayName {Get;Set; }//represents a localized string               PublicIfeaturedependency Featuredependency {Get;Set; }//Functional Characteristics                Public stringIcon {Get;Set; }//Menu Icon                Public BOOLIsLeaf {Get; }//whether there is a submenu                Public VirtualIlist<menuitemdefinition> Items {Get; }//Sub-menu               Public stringName {Get; }//Menu Name                Public intOrder {Get;Set; }//Sort                Public stringRequiredpermissionname {Get;Set; }//Permission Name                Public BOOLrequiresauthentication {Get;Set; }//permission validation is not visible if this menu is displayed by validation                Public stringURL {Get;Set; }//URL        PublicMenuitemdefinition AddItem (menuitemdefinition menuItem);//Add a sub-menu

With attributes and understanding of its role we can easily customize any menu, in general development we may need to load some dynamic menu from database, XML and other data sources to meet our system requirements, with the above objects we can easily add menu!

The Setup menu code is as follows:

  Public classAppnavigationprovider:navigationprovider { Public Override voidsetnavigation (Inavigationprovidercontext context) {#regionStatic menucontext. Manager.mainmenu. AddItem (Newmenuitemdefinition (AppPageNames.Host.Tenants, L ("Hostdashboardmenu"), URL:"Host_dashboard", Icon:"Menu-icon FA fa-home", RequiredPermissionName:PermissionNames.Pages_Host_Dashboard, order:1                    )                ); #endregion            #regionDynamic Menuvarproject=Newmenuitemdefinition (AppPageNames.Common.Project, L ("Projectmenu"), URL:"Roles", Icon:"Menu-icon FA fa-briefcase", requiredPermissionName:PermissionNames.Pages_Administration_Projects, order: 5                    ); //This simulates loading data from a database             for(inti =1; I <=Ten; i++) {Project. AddItem (NewMenuitemdefinition ("P1", L ("Project"+i), url:"Project", Icon:"Menu-icon FA fa-tasks", RequiredPermissionName:PermissionNames.Pages_Administration_Projects, C            USTOMDATA:I)); } context.            Manager.MainMenu.AddItem (project); #endregion                   }        Private StaticIlocalizablestring L (stringname) {            return Newlocalizablestring (name, datacenterconsts.localizationsourcename); }    }

The effect is as follows
