El control DataGridView muestra sus celdas usando los estilos indicados por la propiedad Cell InheritedStyle, que hereda los estilos de otras propiedades de tipo DataGridViewCellStyle.The DataGridView control displays its cells using the styles indicated by the cell InheritedStyle property, which inherits styles from other properties of type DataGridViewCellStyle. En el caso de las celdas de filas con números de índice impares, los estilos especificados mediante la propiedad AlternatingRowsDefaultCellStyle invalidan los estilos especificados mediante los DefaultCellStyle, DataGridViewColumn.DefaultCellStyle y RowsDefaultCellStyle, y se reemplazan por los estilos especificados a través de las propiedades DataGridViewRow.DefaultCellStyle y DataGridViewCell.Style.For cells in rows with odd index numbers, the styles specified through the AlternatingRowsDefaultCellStyle property override the styles specified through the DefaultCellStyle, DataGridViewColumn.DefaultCellStyle, and RowsDefaultCellStyle, and are overridden by the styles specified through the DataGridViewRow.DefaultCellStyle and DataGridViewCell.Style properties.

Al obtener esta propiedad, se creará un DataGridViewCellStyle con valores predeterminados si aún no se ha accedido a la propiedad.When getting this property, a DataGridViewCellStyle with default values will be created if the property has not already been accessed. Esto puede producir un impacto en el rendimiento al obtener esta propiedad para muchas filas.This can cause a performance impact when getting this property for many rows. Siempre que sea posible, use un único DataGridViewCellStyle para establecer esta propiedad para varias filas.Whenever possible, use a single DataGridViewCellStyle to set this property for multiple rows.
