Exemples

L’exemple de code suivant montre comment utiliser cette propriété pour créer un effet comptable dans un contrôle DataGridView.The following code example illustrates how to use this property to create a ledger effect in a DataGridView control.

Remarques

Le contrôle DataGridView affiche ses cellules à l’aide des styles indiqués par la propriété InheritedStyle de la cellule, qui hérite des styles d’autres propriétés de type 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. Pour les cellules de toutes les lignes, à l’exclusion des cellules d’en-tête, les styles spécifiés par le biais de la propriété RowsDefaultCellStyle remplacent les styles spécifiés via les propriétés DefaultCellStyle et DataGridViewColumn.DefaultCellStyle, et sont remplacés par les styles spécifiés par le AlternatingRowsDefaultCellStyle, DataGridViewRow.DefaultCellStyle et DataGridViewCell.Style. sous.For cells in all rows, excluding header cells, the styles specified through the RowsDefaultCellStyle property override the styles specified through the DefaultCellStyle and DataGridViewColumn.DefaultCellStyle properties, and are overridden by the styles specified through the AlternatingRowsDefaultCellStyle, DataGridViewRow.DefaultCellStyle, and DataGridViewCell.Style properties.

Pour plus d’informations, consultez styles de cellule dans le contrôle DataGridView Windows Forms.For more information, see Cell Styles in the Windows Forms DataGridView Control.

Lors de l’obtention de cette propriété, un DataGridViewCellStyle avec des valeurs par défaut est créé si la propriété n’a pas déjà été accédée.When getting this property, a DataGridViewCellStyle with default values will be created if the property has not already been accessed. Cela peut avoir un impact sur les performances lors de l’obtention de cette propriété pour de nombreuses lignes.This can cause a performance impact when getting this property for many rows. Dans la mesure du possible, utilisez une seule DataGridViewCellStyle pour définir cette propriété pour plusieurs lignes.Whenever possible, use a single DataGridViewCellStyle to set this property for multiple rows. Pour plus d'informations, consultez Meilleures pratiques pour la mise à l'échelle du contrôle DataGridView Windows Forms.For more information, see Best Practices for Scaling the Windows Forms DataGridView Control.
