La segunda parte del ejemplo de código es la página web. La página contiene un EditorZone control , que hereda de la ToolZone clase . El Button1_Click método de la página establece el valor de propiedad HeaderCloseVerb .

Tenga en cuenta que después de que se cargue la página, debe cambiar la página al modo de edición para ver los efectos del código que usa la HeaderCloseVerb propiedad en el EditorZone control. Al hacer clic en el botón Habilitar o deshabilitar cerrar verbo , el verbo del encabezado de la zona debe estar habilitado y deshabilitado alternativamente.
