HttpCapabilitiesBase.RequiresAttributeColonSubstitution Propiedad

Definición

Obtiene un valor que indica si el explorador requiere que los dos puntos de los valores de atributo de elemento se sustituyan por un carácter diferente.

public:
 virtual property bool RequiresAttributeColonSubstitution { bool get(); };
public virtual bool RequiresAttributeColonSubstitution { get; }
member this.RequiresAttributeColonSubstitution : bool
Public Overridable ReadOnly Property RequiresAttributeColonSubstitution As Boolean

Valor de propiedad

Boolean

Es true si el explorador requiere que los dos puntos de los valores de atributo de elemento se sustituyan por un carácter diferente; de lo contrario, es false. De manera predeterminada, es false.

Ejemplos

En el ejemplo de código siguiente se muestra cómo determinar si el explorador requiere dos puntos en los valores de atributo de elemento que se van a sustituir por un carácter diferente.

Comentarios

Algunos exploradores no reconocen dos puntos en los valores de atributo de elemento. Si truees , se sustituye un carácter diferente en la representación y se devuelve en los datos de postback.
