Remarques

La classe DataGridViewImageColumn est un type spécialisé de la classe DataGridViewColumn utilisée pour héberger logiquement des cellules qui affichent des images.The DataGridViewImageColumn class is a specialized type of the DataGridViewColumn class used to logically host cells that display images. Un DataGridViewImageColumn est associé à un DataGridViewImageCell dans chaque DataGridViewRow qui l’croise.A DataGridViewImageColumn has an associated DataGridViewImageCell in every DataGridViewRow that intersects it. Chaque cellule peut contenir une Image ou une Icon, en fonction de la valeur de la propriété DataGridViewImageCell.ValueIsIcon.Each cell is capable of containing an Image or an Icon, depending on the value of the DataGridViewImageCell.ValueIsIcon property. L’affichage des icônes est utile pour gérer les images avec transparence.Displaying icons is useful to accommodate images with transparency.

Par défaut, les cellules vides affichent un graphique d’erreur par défaut.By default, empty cells display a default error graphic. Pour empêcher l’affichage de ce graphique pour des valeurs de cellule égales à null ou DBNull.Value, définissez la propriété DataGridViewCellStyle.NullValue de l’objet de style de cellule retourné par la propriété DefaultCellStyle sur null avant d’ajouter des lignes au contrôle.To prevent this graphic from appearing for cell values equal to null or DBNull.Value, set the DataGridViewCellStyle.NullValue property of the cell style object returned by the DefaultCellStyle property to null before adding rows to the control. Toutefois, cela n’affecte pas la ligne pour les nouveaux enregistrements.This does not affect the row for new records, however. Pour éviter que l’image d’erreur n’apparaisse dans la ligne pour les nouveaux enregistrements lorsque la valeur de propriété du contrôle AllowUserToAddRows est true, vous devez également définir explicitement la valeur de la cellule sur null dans un gestionnaire pour l’événement de RowsAdded de contrôle, ou définir la propriété de CellTemplate de colonne sur une instance d’un type dérivé de DataGridViewImageCellavec une propriété de DefaultNewRowValue substituée qui retourne null.To prevent the error graphic from appearing in the row for new records when the control AllowUserToAddRows property value is true, you must also either explicitly set the cell value to null in a handler for the control RowsAdded event or set the column CellTemplate property to an instance of a DataGridViewImageCell-derived type with an overridden DefaultNewRowValue property that returns null.

Le mode de tri par défaut pour ce type de colonne est NotSortable.The default sort mode for this column type is NotSortable.

Notes pour les héritiers

Quand vous dérivez de DataGridViewImageColumn et ajoutez de nouvelles propriétés à la classe dérivée, veillez à substituer la méthode Clone() pour copier les nouvelles propriétés lors des opérations de clonage.When you derive from DataGridViewImageColumn and add new properties to the derived class, be sure to override the Clone() method to copy the new properties during cloning operations. Vous devez également appeler la méthode Clone() de la classe de base afin que les propriétés de la classe de base soient copiées dans la nouvelle cellule.You should also call the base class's Clone() method so that the properties of the base class are copied to the new cell.
