Comentários
Use o Insert método para inserir o objeto especificado MenuItemBinding na coleção no índice especificado.
Observação
Você pode adicionar valores nulos e objetos duplicados MenuItemBinding à coleção.
Como alternativa, você pode simplesmente acrescentar um MenuItemBinding objeto ao final da coleção usando o Add método.
Observação
A ordem na qual MenuItemBinding os objetos aparecem na coleção não tem nenhum efeito sobre como esses objetos são aplicados aos itens de menu em um Menu controle.
