A tabela a seguir mostra o valor da propriedade inicial para uma instância do HtmlInputReset .The following table shows the initial property value for an instance of HtmlInputReset.
| PropriedadeProperty | ValorValue |
|---|---|
| HtmlControl.TagName | O valor do type parâmetro.The value of the type parameter. |
Definir o type parâmetro como um valor não reconhecido como um elemento HTML válido <input> resulta em um elemento HTML padrão <input> como um campo de entrada de texto de linha única.Setting the type parameter to a value not recognized as a valid HTML <input> element results in a default HTML <input> element as a single-line text input field.
