Syntax:

Let’s create Menu using XAML

Here we will create a menu with menu item File and Edit. In the menu item Header includes the name of the menu item. Edit contains sub menus that are Save As and Delete. Sub menus define using MenuItem tag in the Edit menu item.

Now let’s create a menu at Run-time or using code behind.

When we are creating a menu at run-time it will add the menu dynamically. We have to create an object of a menu item and add a menu item object to the Main menu, and for sub menu add an object of the submenu to the corresponding menu item.

Here we are creating a menu the same as created using XAML.

Here, Object of menu item added to the main menu and objects of submenus of Edit added to the menu item Edit.

In the above code, we have created a menu dynamically. Dynamic means which is not fixed or static.

Example

We are creating one simple WPF application with a dynamic menu in which we will bind menus. Here we have created menu items File, Edit, View, and Tool. All menu items and sub-menu items are bind by MenuItems. File and Edit have sub-menu. The file contains 3 more sub-menus New, Open, and Close. New and Open contains submenus New has Project/Solution and Folder and Open has Project/Solution, Repository, and File. Edit contains more sub-menu Cut, Copy and paste.
