Observações
Um LinkLabel controlo não indica automaticamente que um link é um link visitado. Para mostrar o link como um link visitado, pode definir o valor desta propriedade para true num handler de eventos para o evento de clique do LinkLabel. Um link visitado é exibido usando a cor especificada na VisitedLinkColor propriedade do ToolStripLabel controlo.
