The MenuItemCollectionEditor class provides a user interface for editing the MenuItem elements of the collection that is specified by the Items property within the associated Menu control.

The MenuItemCollectionEditor is invoked by selecting the ellipsis () button on the Items property in the Properties grid of the visual designer, or by choosing Edit Menu Items from the Common Tasks context menu on the control.

The EditValue method edits the values of the menu item collection of the associated Menu control. The GetEditStyle method gets the editing style that is associated with this editor.

The following code example shows how to use the EditorAttribute attribute to associate the MenuItemCollectionEditor and UITypeEditor (the collection editor base class) classes with a property in a custom control, derived from the WebControl class, that gets and sets a MenuItemCollection collection.

private MenuItemCollection menuItems;

// Associate the MenuItemCollectionEditor with the Items. 
[Editor(typeof(System.Web.UI.Design.WebControls.
    MenuItemCollectionEditor),
    typeof(UITypeEditor))]
public MenuItemCollection Items
{
    get
    {
        // If there is no menuItems collection, create it. 
        if (menuItems == null)
            menuItems = new MenuItemCollection();

        return menuItems;
    }
    set { menuItems = value; }
} // Items
