Comentários

Um LinkLabel controle não indica automaticamente que um link é um link visitado. Para exibir o link como um link visitado, você pode definir o valor dessa propriedade como true em um manipulador de eventos para o evento de clique do LinkLabel. Um link visitado é exibido usando a cor especificada na VisitedLinkColor propriedade do ToolStripLabel controle.
