Exemples

L’exemple de code suivant ajuste les bordures de cellule d’un DataGridView afin qu’une double bordure sépare les cellules intérieures et la cellule d’en-tête supérieure gauche à partir des en-têtes de ligne et de colonne. Cet exemple montre comment remplacer les méthodes et AdjustRowHeaderBorderStyleles AdjustColumnHeaderBorderStyleméthodes, ainsi AdjustCellBorderStyle que la AdjustedTopLeftHeaderBorderStyle propriété. Ces membres utilisent des DataGridViewAdvancedBorderStyle objets pour modifier des bordures de cellule individuelles.

Remarques

Le DataGridView contrôle vous permet de personnaliser entièrement son apparence, y compris les bordures des cellules et des en-têtes. Les DataGridView propriétés et RowHeadersBorderStyle les ColumnHeadersBorderStylepropriétés CellBorderStylequi vous permettent de définir l’apparence de la bordure de cellule. Toutefois, si vous devez personnaliser davantage les bordures, la DataGridViewAdvancedBorderStyle classe vous permet de définir le style de la bordure sur les côtés individuels des cellules. Les Leftpropriétés et TopBottom les Rightpropriétés de DataGridViewAdvancedBorderStyle représenter respectivement la bordure gauche, droite, supérieure et inférieure d’une cellule. Vous pouvez définir ces propriétés sur les AdvancedCellBorderStylepropriétés , AdvancedRowHeadersBorderStyle AdvancedColumnHeadersBorderStyleles propriétés du DataGridView pour produire diverses apparences pour les bordures entre les cellules.
