Ejemplos

En el ejemplo de código siguiente se muestra cómo utilizar esta propiedad en un control DataGridView diseñado principalmente para la presentación.The following code example illustrates how to use this property in a DataGridView control intended primarily for display. En este ejemplo, la apariencia visual del control se personaliza de varias maneras y el control se configura para una interactividad limitada.In this example, the visual appearance of the control is customized in several ways and the control is configured for limited interactivity. Este ejemplo forma parte de un ejemplo más grande disponible en la información general de la clase DataGridViewCellStyle.This example is part of a larger example available in the DataGridViewCellStyle class overview.

    // limited interactivity.

Comentarios

Utilice esta propiedad para evitar que los usuarios cambien manualmente el alto de las filas.Use this property to prevent users from manually changing row heights. Esto resulta útil, por ejemplo, con controles de solo visualización en los que los datos se cargan una vez y se cambia el tamaño de las filas en ese momento.This is useful, for example, with display-only controls where data is loaded once and rows are resized at that time.

Para que el contenido de la celda se ajuste en varias líneas cuando se cambia el tamaño de una fila, el estilo de celda en vigor para la celda debe tener un valor de propiedad WrapMode de True.For cell contents to wrap onto multiple lines when a row is resized, the cell style in effect for the cell must have a WrapMode property value of True.

Para obtener más información sobre el cambio de tamaño del usuario, consulte Opciones de ajuste de tamaño en el control DataGridView Windows Forms.For more information about user resizing, see Sizing Options in the Windows Forms DataGridView Control.

Nota

El control DataGridView no admite el almacenamiento en búfer doble.The DataGridView control does not support double buffering. Si DoubleBuffered se establece en true en un control derivado de @no__t 2, los usuarios no recibirán comentarios visuales al cambiar el tamaño de filas, columnas o encabezados o al reordenar columnas.If DoubleBuffered is set to true in a derived DataGridView control, users will not receive visual feedback when resizing rows, columns, or headers or when reordering columns.
