Commenti

Se il valore della proprietà è impostato truesu, il componente a DesignerActionList cui è associato verrà automaticamente espanso e visualizzato il pannello smart tag quando il componente viene creato.If the property value is set to true, the component with which this DesignerActionList is associated will automatically expand and display the smart tag panel when the component is created.

È possibile rifiutare esplicitamente questo comportamento impostando la DesignerOptions.ObjectBoundSmartTagAutoShow proprietà su false.You can opt out of this behavior by setting the DesignerOptions.ObjectBoundSmartTagAutoShow property to false.
