La IDesigner interfaz proporciona una interfaz a través de la cual puede implementar servicios básicos para un diseñador.The IDesigner interface provides an interface through which you can implement basic services for a designer. Un diseñador puede modificar el comportamiento de un componente en tiempo de diseño y puede proporcionar sus propios servicios y su comportamiento.A designer can modify the behavior of a component at design time, and may provide its own services and behavior. Un diseñador solo está activo en tiempo de diseño y debe estar asociado a un tipo de componente mediante DesignerAttribute para que se pueda cargar cuando se crea un componente del tipo asociado en tiempo de diseño.A designer is only active at design-time, and must be associated with a type of component using a DesignerAttribute in order to be loaded when a component of the associated type is created at design time.

La IDesigner interfaz proporciona métodos y propiedades que se pueden implementar para proporcionar un comportamiento personalizado en tiempo de diseño.The IDesigner interface provides methods and properties that you can implement in order to provide custom behavior at design time.

Implemente Initialize el método de un diseñador para realizar acciones cuando se crea un componente.Implement the Initialize method of a designer to perform actions when a component is created. Esto puede ser útil si un componente debe tener una configuración especial en tiempo de diseño o si su configuración debe cambiar en función de las condiciones que el diseñador pueda determinar.This can be useful if a component should have a special configuration at design-time, or if its configuration should change depending on conditions that the designer can determine.

Un diseñador puede proporcionar comandos de menú en el menú contextual que se muestra cuando un usuario hace clic con el botón secundario en un componente o control en el entorno de tiempo de diseño.A designer can provide menu commands on the shortcut menu that is displayed when a user right-clicks a component or control in the design-time environment. Puede implementar la Verbs propiedad para definir un descriptor de acceso get que devuelve DesignerVerb un DesignerVerbCollection que contiene los objetos para generar comandos de menú.You can implement the Verbs property to define a get accessor that returns a DesignerVerbCollection containing the DesignerVerb objects for generating menu commands.

Un diseñador para un componente que aparece en la bandeja de componentes puede realizar una acción predeterminada cuando se hace doble clic en el componente.A designer for a component that appears in the component tray can perform a default action when the component is double-clicked. Implemente DoDefaultAction el método para especificar el comportamiento que se va a realizar cuando se haga doble clic en el componente.Implement the DoDefaultAction method to specify the behavior to perform when the component is double-clicked.

Un diseñador también puede utilizar los servicios en tiempo de diseño disponibles para realizar una serie de tareas, como la encuesta del entorno en tiempo de diseño actual para los componentes y sus propiedades, leer y establecer los valores de las propiedades de los componentes, administrar el cuadro de herramientas, administrar componentes seleccionados o mostrar una interfaz de usuario que se puede usar para configurar valores o para aplicar más procesamiento.A designer can also use the available design-time services to perform a variety of tasks, including surveying the current design-time environment for components and their properties, reading and setting the values of properties of components, managing the toolbox, managing selected components, or displaying a user interface that can be used to configure values or to apply further processing.

Para implementar un diseñador para un control que se puede colocar en un formulario, puede heredar de la ControlDesigner clase.To implement a designer for a control that can be sited on a form, you can inherit from the ControlDesigner class. Los controles cuyo diseñador asociado no se deriva ControlDesigner de se muestran en la bandeja de componentes.Controls whose associated designer does not derive from ControlDesigner are displayed in the component tray. Las ComponentDesigner clases ControlDesigner y implementan IDesigner la interfaz y proporcionan compatibilidad adicional en tiempo de diseño que puede ser de uso para los autores de diseñadores.The ComponentDesigner and ControlDesigner classes implement the IDesigner interface and provide additional design-time support that may be of use to authors of designers. Para obtener más información, vea la documentación de referencia de estas clases.For more information, see the reference documentation for these classes.

Para obtener información general sobre la creación de componentes de diseño, vea extender la compatibilidad en tiempo de diseño.For an overview of creating design components, please see Extending Design-Time Support.
