virtual property System::String ^ Text { System::String ^ get(); void set(System::String ^ value); };
public virtual string Text { get; set; }
member this.Text : string with get, set
Public Overridable Property Text As String
Valor da propriedade
Uma cadeia de caracteres que contém o rótulo de texto para um verbo. O padrão é uma cadeia de caracteres vazia ("").
Exemplos
O exemplo de código a seguir mostra como substituir a Text propriedade em uma classe derivada herdada de WebPartVerb. Esse código-fonte mostra apenas a parte do código para a zona personalizada e a WebPartVerb classe que substitui a propriedade . O restante do código necessário para executar o exemplo pode ser encontrado na seção Exemplo da visão geral da WebPartVerb classe.
Depois de carregar a página em um navegador, observe que o valor atribuído à Text propriedade no código-fonte aparece no menu de verbos do WebPart controle.

Comentários
Essa propriedade define o texto do rótulo de um WebPartVerb objeto; é o que representa o verbo para os usuários na interface do usuário.
Se os desenvolvedores (opcionalmente) atribuirem um valor à ImageUrl propriedade, uma imagem ou ícone representará o verbo na interface do usuário e, em determinados casos (como quando o verbo normalmente é renderizado por um botão ou hiperlink), a imagem aparecerá em vez do rótulo de texto.
