Editor de cuadro de diálogo modal personalizado para la configuración del adaptador
El código del editor personalizado muestra un editor derivado de la clase System.Drawing.Design.UITypeEditor que muestra un cuadro de diálogo emergente modal para escribir una contraseña. La invalidación del método GetEditStyle devuelve UIEditorEditStyle.Modal para indicar un subcontrol de formulario modal. El método de servicio ShowDialog administra el control creado con CreatePassword. ShowDialog devuelve un dialogResult que se controla de la manera habitual (por ejemplo, una instrucción switch) con el valor de cambio de mayúsculas y minúsculas DialogResult.OK .
El código siguiente es la definición de clase del editor modal personalizado:
