ControlBuilder.HasAspCode Propriété

public:
 property bool HasAspCode { bool get(); };

public:
 virtual property bool HasAspCode { bool get(); };

public bool HasAspCode { get; }

public virtual bool HasAspCode { get; }

member this.HasAspCode : bool

Public ReadOnly Property HasAspCode As Boolean

Public Overridable ReadOnly Property HasAspCode As Boolean

Valeur de propriété

Boolean

true si le contrôle contient un ou plusieurs blocs de code ; sinon, false.

Exemples

Cet exemple remplace la OnAppendToParentBuilder méthode pour vérifier la ControlType propriété pour déterminer le type de contrôle auquel ce générateur est appliqué. S’il s’agit d’un CustomTextBox, le générateur vérifie si la valeur de la HasAspCode propriété est incluse dans le contrôle. Si c’est le cas, une exception est levée, sinon la HasBody méthode est appelée.
