Exemples

L’exemple de code suivant crée un Windows Form avec un DataGridView et un ensemble de boutons. Chaque étiquette de bouton décrit une opération liée à une DataGridViewColumn propriété, telle que l’échange de la première et de la dernière colonne (à l’aide de la DisplayIndex propriété) ou la modification du texte d’un en-tête de colonne (à l’aide de la HeaderText propriété ). Cliquer sur un bouton modifie la propriété associée du DataGridViewColumn.

Remarques

La DataGridViewColumn classe représente une colonne logique dans un DataGridView contrôle. Vous pouvez récupérer des colonnes via la Columns collection du contrôle .

Contrairement à un DataGridViewRow, qui contient la collection réelle de cellules d’un DataGridView, DataGridViewColumn est principalement utilisé pour ajuster l’apparence et le comportement de l’interface utilisateur de colonne, comme la largeur de colonne et le style de cellule. Pour plus d’informations sur les styles de cellule, consultez Styles de cellule dans le contrôle DataGridView Windows Forms.

Les types qui dérivent généralement d’initialiser DataGridViewColumn la CellTemplate propriété vers une nouvelle instance d’un type associé dérivé de la DataGridViewCell classe . Toutes les propriétés de colonne qui se rapportent à l’apparence ou au comportement de cellules individuelles sont des wrappers pour les propriétés correspondantes de la cellule de modèle. La modification de l’une de ces propriétés sur la colonne modifie automatiquement la valeur sur le modèle de cellule et sur toutes les cellules de la colonne. Pour remplacer la valeur spécifiée pour les cellules individuelles, définissez les valeurs de cellule après avoir défini la valeur de colonne.

Notes pour les héritiers

Lorsque vous dérivez de DataGridViewColumn et ajoutez de nouvelles propriétés à la classe dérivée, veillez à remplacer la Clone() méthode pour copier les nouvelles propriétés pendant les opérations de clonage. Vous devez également appeler la méthode de la classe de Clone() base afin que les propriétés de la classe de base soient copiées dans la nouvelle cellule.
