Procedimiento para delimitar y acoplar controles secundarios en un control FlowLayoutPanel

El control FlowLayoutPanel admite las propiedades Anchor y Dock en sus controles secundarios.

Para delimitar y acoplar controles secundarios en un control FlowLayoutPanel

  1. Cree un control FlowLayoutPanel en el formulario.

  2. Establezca el valor de Width del control FlowLayoutPanel en 300 y establezca el valor de FlowDirection en TopDown.

  3. Cree dos controles Button y colóquelos en el control FlowLayoutPanel.

  4. Establezca el valor de Width del primer botón en 200.

  5. Establezca la propiedad Dock del segundo botón en Fill.

    Nota

    El segundo botón toma el mismo ancho que el primer botón. No se ajusta a lo ancho del control FlowLayoutPanel.

  6. Establezca la propiedad Dock del segundo botón en None. Esto hace que el botón tome su ancho original.

  7. Establezca la propiedad Anchor del segundo botón en Left, Right.

    Importante

    El segundo botón toma el mismo ancho que el primer botón. No se ajusta a lo ancho del control FlowLayoutPanel. Esta es la regla general para delimitar y acoplar en el control FlowLayoutPanel: para direcciones de flujo verticales, el control FlowLayoutPanel calcula el ancho de una columna implícita a partir del control secundario más ancho de la columna. Todos los demás controles de esta columna con propiedades Anchor o Dock se alinean o cambian de tamaño para ajustarse a esta columna implícita. El comportamiento funciona de forma similar para las direcciones de flujo horizontales. El control FlowLayoutPanel calcula el alto de una fila implícita a partir del control secundario más alto de la fila, y todos los controles secundarios delimitados o acoplados de esta fila se alinean o cambian de tamaño para ajustarse a la fila implícita.

Ejemplo

La ilustración siguiente muestra cuatro botones que se delimitan y se acoplan con relación al botón azul en un FlowLayoutPanel. El valor de FlowDirection es LeftToRight.

Captura de pantalla del control FlowLayoutPanel horizontal, con cuatro botones anclados y acoplados al botón centrado.

La ilustración siguiente muestra cuatro botones que se delimitan y se acoplan con relación al botón azul en un FlowLayoutPanel. El valor de FlowDirection es TopDown.

Captura de pantalla del control FlowLayoutPanel vertical, con cuatro botones anclados y acoplados al botón centrado.

En el ejemplo de código siguiente se muestran varios valores de propiedad Anchor para un control Button en un control FlowLayoutPanel.
