Ejemplos

En el ejemplo de código siguiente se muestra el efecto de establecer las propiedades en varios servidores DataGridViewCellStyle objetos.The following code example demonstrates the effect of setting properties on multiple DataGridViewCellStyle objects. Este ejemplo establece el color de fondo de las celdas de la DataGridView estableciendo el BackColor propiedad en el DefaultCellStyle propiedad.This example sets the background color of cells in the DataGridView by setting the BackColor property on the DefaultCellStyle property. El color de fondo se reemplaza en filas alternas porque la BackColor propiedad está establecida en el AlternatingRowsDefaultCellStyle propiedad.The background color is overridden on alternating rows because the BackColor property is set on the AlternatingRowsDefaultCellStyle property. El ejemplo también determina el formato de fechas en la columna denominada Last Prepared estableciendo el Format propiedad en la columna DefaultCellStyle propiedad.The example also determines the format of dates in the column named Last Prepared by setting the Format property on the column's DefaultCellStyle property.

Comentarios

El DataGridViewCellStyle clase le permite compartir información de estilo entre varios DataGridView celdas, filas, columnas y encabezados de fila o columna, evitando los requisitos de memoria de establecer las propiedades de estilo en celdas individuales.The DataGridViewCellStyle class lets you share style information across multiple DataGridView cells, rows, columns, and row or column headers, avoiding the memory requirements of setting style properties on individual cells. Para obtener más información acerca de las clases que tienen una propiedad de tipo DataGridViewCellStyle y cómo se relacionan entre sí, consulte estilos de celda en el DataGridView Control de Windows Forms.For more information about classes that have a property of type DataGridViewCellStyle and how they relate to each other, see Cell Styles in the Windows Forms DataGridView Control.
