Exemples

L’exemple de code suivant illustre l’utilisation de cette propriété dans un contrôle DataGridView, principalement destiné à l’affichage.The following code example illustrates how to use this property in a DataGridView control intended primarily for display. Dans cet exemple, l’apparence visuelle du contrôle est personnalisée de plusieurs façons et le contrôle est configuré pour une interactivité limitée.In this example, the visual appearance of the control is customized in several ways and the control is configured for limited interactivity. Cet exemple fait partie d’un exemple plus complet disponible dans la vue d’ensemble de la classe DataGridViewCellStyle.This example is part of a larger example available in the DataGridViewCellStyle class overview.

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 cette ligne, les styles spécifiés par le biais de la propriété DefaultCellStyle substituent les styles spécifiés via les propriétés DataGridView.DefaultCellStyle, DataGridViewColumn.DefaultCellStyle, DataGridView.RowsDefaultCellStyleet DataGridView.AlternatingRowsDefaultCellStyle, mais sont substitués par les styles spécifiés par le biais de la propriété DataGridViewCell.Style.For cells in this row, the styles specified through the DefaultCellStyle property override the styles specified through the DataGridView.DefaultCellStyle, DataGridViewColumn.DefaultCellStyle, DataGridView.RowsDefaultCellStyle, and DataGridView.AlternatingRowsDefaultCellStyle properties, but are overridden by the styles specified through the DataGridViewCell.Style property.

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.
