System.Windows.Forms 1.0.5000.0 2.0.0.0 System.ComponentModel.Component System.ComponentModel.ListBindable(false) System.ComponentModel.ToolboxItemFilter("System.Windows.Forms", System.ComponentModel.ToolboxItemFilterType.Allow) This class is the base class for the , , and classes. You cannot create an instance of this class. The menus for an application consist of objects. These can contain other objects, representing submenu items. The objects can be stored in a for display as an entire menu structure for a form or a that is used to display shortcut menus. This class provides functionality that is common for all the menu classes. Unlike many base classes, the class uses its derived classes to define many of its properties. If you are using your menu in a multiple-document interface (MDI) application, you can use the property to specify a that displays a list of open MDI child forms in your application. The property contains a list of objects stored in the menu class. For a or , this property contains all the objects that are displayed. For a , the property represents the submenu items associated with it. In addition to the properties that are provided for all the derived menu classes, the class also provides methods, such as and , that enable you to create new menus from existing menus, and also merge two menu structures together. The class also defines the nested class . This class defines the collection of objects used by the property. You can use the methods of the class to add and remove menu items from a , , or .

Represents the base functionality for all menus. Although and replace and add functionality to the control of previous versions, is retained for both backward compatibility and future use if you choose.

1.0.5000.0 2.0.0.0 Method System.Windows.Forms.ContextMenu This method allows you to obtain a reference to the that this menu is contained in. This property returns null if the menu is not contained in a . This can occur if the menu is contained in a or , or if the menu is not contained in any menu. You can use this property to determine whether a menu is currently being used, and also to determine where.

You can use this property to obtain the handle to the menu to perform special operations to the menu outside of the functionality provided by this class or its derived classes.

Gets a value representing the window handle for the menu.

1.0.5000.0 2.0.0.0 Property System.ComponentModel.DesignerSerializationVisibility(System.ComponentModel.DesignerSerializationVisibility.Hidden) System.ComponentModel.Browsable(false) System.Boolean To be added. You can use this method to determine whether any objects are assigned to this menu. This is equivalent to checking for null in the property.

Gets a value indicating whether this menu contains any menu items. This property is read-only.

You can use this property to obtain a reference to the list of menu items that are currently stored in the menu. For and objects, the property contains the entire menu structure in the control. For the class, the property contains the list of submenu items associated with the . With the reference to the collection of menu items for the menu (provided by this property), you can add and remove menu items, determine the total number of menu items, and clear the list of menu items from the collection. For more information on maintaining the menu item collection for a menu, see the documentation.

Gets a value indicating the collection of objects associated with the menu.

1.0.5000.0 2.0.0.0 Method System.Void This method merges objects from one menu with the current menu. objects are merged according to the values of the and properties. Menu merging is typically done to merge the menus of a Multiple Document Interface (MDI) parent form with those of its active MDI child form. This is performed automatically by the .NET Framework common language runtime. For example, if an MDI parent form contains a set of menus for handling files and your MDI child form also has file-related menu items, the menu sets will automatically merge into a single file menu set when the child form is displayed in the MDI parent form. You can use the method if you are merging two menu structures that are not part of an MDI application. This implementation can be called by the or classes to merge two or more objects that derive from . To merge two objects use the method.
